Delivery and transportation
Delivery arrangements
Delivery within the United States or Canada is by air-ride truck with custom-designed
shipping material, crate, and pallet. International delivery normally involves air freight.
Unless otherwise instructed, the EMC Traffic Department arranges for delivery directly to
the customer’s computer room. To ensure successful delivery of the system, EMC has
formed partnerships with specially selected moving companies. These companies have
moving professionals trained in the proper handling of large, sensitive equipment. These
companies provide the appropriate personnel, floor layments, and any ancillary moving
equipment required to facilitate delivery. Moving companies should check general
guidelines, weights, and dimensions.
NOTICE
Inform EMC of any labor union-based restrictions or security clearance requirements prior
to delivery.
Pre-delivery considerations
Take into account the following considerations prior to the delivery at your site:
l
Weight capacities of the loading dock, tailgate, and service elevator if delivery is to a
floor other than the receiving floor.
l
Length and thickness of covering required for floor protection.
l
Equipment ramp needed if the receiving floor is not level with computer room floor.
Moving up and down inclines
To prevent tipping when moving up and down inclines, the following guidelines are
recommended:
l
When moving cabinets, all doors/drawers should be closed.
l
When moving the cabinet down an incline, the front of the cabinet must go first.
l
When moving the cabinet up an incline, the rear of the bay goes last.
All portions of the bay will clear ramp and threshold slopes up to 1:10 (rise to run ratio),
per Code of Federal Regulations — ADA Standards for Accessible Design, 28 CFR Part 36.

Specifications
Radio frequency interference
Electro-magnetic fields, which include radio frequencies can interfere with the operation
of electronic equipment. EMC Corporation products have been certified to withstand
radio frequency interference (RFI) in accordance with standard EN61000-4-3. In Data
Centers that employ intentional radiators, such as cell phone repeaters, the maximum
ambient RF field strength should not exceed 3 Volts /meter.
The field measurements should be taken at multiple points in close proximity to EMC
Corporation equipment. It is recommended to consult with an expert prior to installing
any emitting device in the Data Center. In addition, it may be necessary to contract an
environmental consultant to perform the evaluation of RFI field strength and address the
mitigation efforts if high levels of RFI are suspected.
The ambient RFI field strength is inversely proportional to the distance and power level of
the emitting device.
Recommended minimum distance from RF emitting device
The following table provides the recommended minimum distances between EMC arrays
and RFI emitting equipment. Use these guidelines to verify that cell phone repeaters or
other intentional radiator devices are at a safe distance from the EMC Corporation
equipment.

Power consumption and heat dissipation
EMC provides the EMC Power Calculator to refine the power and heat figures to more
closely match your array. Contact your EMC Sales Representative or use the EMC Power
Calculator for specific supported configurations. The following table provides calculations
of maximum power and heat dissipation.
NOTICE
Power consumption and heat dissipation details vary based on the number of system and
storage bays. Ensure that the installation site meets these worst case requirements.

within their enclosures. Based on ambient temperature and internal activity, they set the
cooling fan speeds. The power values above are for a standard data center environment.
Adaptive cooling will increase the power dissipation over these numbers if the ambient
temperature exceeds 35°C. If the temperature of the local environment reaches or
exceeds 35°C, each DAE and engine in the array increases power and heat dissipation by
the following values:
l
DAE120 (2.5 Drives) = 305VA - 1024 BTU/hr
l
DAE60 (3.5 Drives) = 265VA - 904 BTU/hr

Airflow
VMAX3 systems are designed for typical hot aisle/cold aisle data center cooling
environments and installation:
l
On raised or nonraised floors.
l
In hot aisle/cold aisle arrangements.
The airflow provides less mixing of hot and cold air, which can result in a higher return
temperature to the computer room air conditioner (CRAC). This promotes better heat
transfer outside the building and achieves higher energy efficiency and lower Power
Usage Effectiveness (PUE). Additional efficiency can be achieved by sequestering the
exhaust air completely and ducting directly to a CRAC unit or to the outside.
EMC recommends the placement of a perforated floor tile in front of each bay to allow
adequate cooling air supply when installing on a raised floor. The following figure shows
typical airflow in a hot aisle/ cold aisle environment.

Air quality requirements
VMAX3 arrays are designed to be consistent with the requirements of the American
Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) Environmental
Standard Handbook and the most current revision of Thermal Guidelines for Data
Processing Environments, ASHRAE TC 9.9 2011.
The VMAX3 arrays are best suited for Class 1A Datacom environments, which consist of
tightly controlled environmental parameters, including temperature, dew point, relative
humidity and air quality. These facilities house mission critical equipment and are
typically fault tolerant, including the air conditioners. In a data center environment, if the
air conditioning fails and the temperature is lost, a vault may occur to protect data.
The data center should maintain a cleanliness level as identified in ISO 14664-1, class 8
for particulate dust and pollution control. The air entering the data center should be
filtered with a MERV 11 filter or better. The air within the data center should be
continuously filtered with a MERV 8 or better filtration system. In addition, efforts should
be maintained to prevent conductive particles, such as zinc whiskers, from entering the
facility.
The allowable relative humidity level is 20–80% non condensing, however, the
recommended operating environment range is 40–55%. For data centers with gaseous
contamination, such as high sulfur content, lower temperatures and humidity are
recommended to minimize the risk of hardware corrosion and degradation. In general,
the humidity fluctuations within the data center should be minimized. It is also
recommended that the data center be positively pressured and have air curtains on entry
ways to prevent outside air contaminants and humidity from entering the facility.
For facilities below 40% relative humidity (RH), EMC recommends using grounding straps
when contacting the equipment to avoid the risk of electrostatic discharge (ESD), which
can harm electronic equipment.
Note
As part of an ongoing monitoring process for the corrosiveness of the environment, EMC
recommends placing copper and silver coupons (per ISA 71.04-1985, Section 6.1
Reactivity) in airstreams representative of those in the data center. The monthly reactivity
rate of the coupons should be less than 300 Angstroms. When monitored reactivity rate
is exceeded, the coupon should be analyzed for material species and a corrective
mitigation process emplaced.

Data center safety and remote support
Fire suppressant disclaimer
Always install fire prevention equipment in the computer room as an added safety
measure. A fire suppression system is the responsibility of the customer. When selecting
appropriate fire suppression equipment and agents for their data center, choose
carefully. Your insurance underwriter, local fire marshal, and local building inspector are
all parties that you should consult during the selection a fire suppression system that
provides the correct level of coverage and protection.
EMC designs and manufactures equipment to internal and external standards that
require certain environments for reliable operation. EMC does not make compatibility
claims of any kind nor does EMC provide recommendations on fire suppression systems.
EMC does recommend that you do not position storage equipment directly in the path of
high pressure gas discharge streams or loud fire sirens so as to minimize the forces and
vibration adverse to system integrity.
Note
The previous information is provided on an “as is” basis and provides no
representations, warranties, guarantees or obligations on the part of EMC Corporation.
This information does not modify the scope of any warranty set forth in the terms and
conditions of the basic purchasing agreement between the customer and EMC
Corporation.
Remote support
EMC Secure Remote Support (ESRS) is an IP-based, automated, connect home and
remote support solution. ESRS is the preferred method of connectivity. EMC recommends
using two connections with ESRS for connection to the redundant management module
control station (MMCS).
ESRS customers must provide the following:
l
An IP network with Internet connectivity.
l
Capability to add Gateway Client servers and Policy Manager servers to the customer
network.
l
Network connectivity between the servers and EMC devices to be managed by ESRS
l
Internet connectivity to EMC’s ESRS infrastructure by using outbound ports.
l
Network connectivity between ESRS Client(s) and Policy Manager.
Once installed, ESRS monitors the array and automatically notifies EMC Customer Service
in the event of a problem. If an error is detected, an EMC support professional utilizes the
secure connection to establish a remote support session to diagnose, and if necessary,
perform a repair.
EMC Customer Service can use ESRS to:
l
Perform downloads of updated software in lieu of a site visit.
l
Deliver license entitlements directly to the array.

Floor load-bearing capacity
VMAX3 arrays can be installed on raised floors. Customers must be aware that the loadbearing capacity of the data center floor is not readily available through a visual
inspection of the floor. The only definitive way to ensure that the floor is capable of
supporting the load associated with the array is to have a certified architect or the data
center design consultant inspect the specifications of the floor to ensure that the floor is
capable of supporting the VMAX3 array weight.
CAUTION
l
Customers are ultimately responsible for ensuring that the floor of the data center
on which the VMAX3 array is to be configured is capable of supporting the array
weight, whether the array is configured directly on the data center floor or on a
raised floor supported by the data center floor.
l
Failure to comply with these floor loading requirements could result in severe
damage to the VMAX3 array, the raised floor, subfloor, site floor and the surrounding
infrastructure should the raised floor, subfloor or site floor fail.
l
Notwithstanding anything to the contrary in any agreement between EMC and
customer, EMC fully disclaims any and all liability for any damage or injury resulting
from customer’s failure to ensure that the raised floor, subfloor and/or site floor are
capable of supporting the VMAX3 array weight. The customer assumes all risk and
liability associated with such failure.
Raised floor requirements
EMC recommends the use of 24 x 24 inch heavy-duty, concrete-filled steel floor tiles. If a
different size or type of tile is used, the customer must ensure that the tiles have a
minimum load rating that is sufficient for supporting the VMAX3 array weight. Ensure
proper physical support of the system by following requirements that are based on the
use of 24 x 24 in. (61 x 61 cm) heavy-duty, concrete-filled steel floor tiles.
Raised floors must meet the following requirements:
l
Floor must be level.
l
Floor tiles and stringers must be rated to withstand concentrated loads of two casters
each that weigh up to 700 lb (317.5 kg).
Note
Caster weights are measured on a level floor. The front of the VMAX3 array weighs more
than the rear of the configuration.
38
l
Floor tiles and stringers must be rated for a minimum static ultimate load of 3,000 lb
(1,360.8 kg).
l
Floor tiles must be rated for a minimum of 1,000 lb (453.6 kg) on rolling load.
l
For floor tiles that do not meet the minimum rolling load rate, EMC recommends the
use of coverings, such as plywood, to protect floors during system roll.
l
Floor tile cutouts weaken the tile. EMC recommends an additional pedestal mount
adjacent to the cutout of a tile. The number and placement of additional pedestal
mounts relative to a cutout are to be in accordance with the tile manufacturer’s
Site Planning Guide VMAX 100K, VMAX 200K, VMAX 400K, with HYPERMAX OS
Physical weight and space
recommendations. Floor tile deflection should be minimized with additional pedestal
mounts.
l
Take care when positioning the bays to make sure that a caster is not moved into a
cutout. Cutting tiles per specifications ensures the proper caster placement.
l
Use or create no more than one floor tile cutout that is no more than 8 in. (20 cm)
wide by 6 in. (15 cm) deep in each 24 x 24 in. (61 x 61 cm) floor tile.
l
Ensure that the weight of any other objects in the data center does not compromise
the structural integrity of the raised floor or the subfloor (nonraised floor) of the data
center.

System bay layouts
The number of bays and the system layout depend on the array model, the customer
requirements, and the space and organization of the customer data center.
VMAX3 Family arrays can be placed in the following layouts:
l
Adjacent — all bays are positioned side-by-side.
l
Dispersed — dispersed layouts are provided with longer fabric and Ethernet cable
bundles that allow 82 ft (25 m) of separation between system bay 1 and system bays
2 through 8.
Dispersed system bays require dispersed cable and optics kits and one set of side
skins for each dispersed system bay in the configuration.
Note
l
n
The routing strategy (beneath raised floor or overhead), site requirements, and the
use of GridRunners (optional) or cable troughs can cause the actual distances to
vary.
n
GridRunners are used to create a strain relief for all dispersed, under the floor,
cable bundles. GridRunners are installed in the locations where the cable bundle
enters and exits the area under the raised floor.
Adjacent and dispersed bays (mixed) layouts — allow both adjacent and dispersed
layout of either single or dual-engine arrays with adjacent and dispersed bays.
Note
Single and dual-engine arrays cannot be mixed.

Caster and leveler dimensions
The bay(s) bottom includes four caster wheels. The front wheels are fixed; the two rear
casters swivel in a 1.75-in. diameter. Swivel position of the caster wheels determines the
load-bearing points on your site floor, but does not affect the cabinet footprint. Once you
have positioned, leveled, and stabilized the bay(s), the four leveling feet determine the
final load-bearing points on your site floor.
The following figure shows caster and leveler dimensions.

Power distribution unit
The VMAX3 array is powered by two redundant power distribution units (PDUs), one PDU
for each power zone.
Both PDUs are mechanically connected together, including mounting brackets, to create
a single 2U structure, as shown in the following figures. The PDUs are integrated to
support AC-line input connectivity and provide outlets for every component in the bay.
The PDU is available in three wiring configurations that include:
l
Single-phase
l
Three-phase Delta
l
Three-phase Wye
Note
The PDU AC power cords (single-phase and three-phase) extend 74" (188cm) from the
PDU chassis and are designed to reach to the bay floor egress for connection to the
customer power supply. 15' (4.57m) extension cables are provided.
Each PDU provides the following components:
l
A total of 24 power outlets for field replaceable units (FRUs). The outlets are divided
into six banks with each bank consisting of four IEC 60320 C13 individual AC outlets.
l
Each bank of outlets is connected to individual branch circuits that are protected by a
single two pole 20 Amp circuit breaker.
l
Depending on which PDU option selected there is a different input connector for each
PDU.
If the customer requires power to be supplied from overhead, EMC recommends replacing
the rear top cover of the bay with the ceiling routing top cover, described in Overhead
routing kit on page 84, which allows the power cables inside the machine to be routed
out through the top.
A second option is to "drop" the power cables down the hinge side, to the bottom, and
route them inside the machine. The cables should be dressed to allow all doors to open
freely and space should be provisioned accordingly to accommodate an adjacent
cabinet.

Power cabling, cords and connectors
Each VMAX3 bay in a system configuration contains a complete 2U PDU assembly. The
PDU assembly is constructed with two electrically individual PDUs.
NOTICE
Customers are responsible for meeting all local electrical safety requirements.
Customer input power cabling
Before the array is delivered, the customer must supply and install the required
receptacles on the customer’s PDUs for zone A and zone B power for the system bay.
NOTICE
EMC recommends that the customer's electrician be present at installation time to work
with the EMC Customer Engineer to verify power redundancy.
Refer to the EMC VMAX Best Practices Guide for AC Power Connections for required items at
the customer site.
Best practices: Power configuration guidelines
The following section provides best practice guidelines for evaluating and connecting
power, as well as for choosing a UPS component.
Uptime Institute best practices
Follow these best practice guidelines when connecting AC power to the VMAX3 array:
l
The EMC customer engineer (CE) should discuss with the customer the need for
validating AC power redundancy at each bay. If the power redundancy requirements
are not met in each EMC bay, a Data Unavailable (DU) event could occur.
l
The customer should complete power provisioning with the data center prior to
connecting power to the VMAX3 array.
l
The customer‘s electrician or facilities representative must verify that the AC voltage
is within specification at each of the power drops being fed to each EMC product bay.
l
All of the power drops should be labeled to indicate the source of power (PDU) and
the specific circuit breakers utilized within each PDU:
l
n
Color code the power cables to help achieve redundancy.
n
Clearly label the equipment served by each circuit breaker within the customer
PDU.
The electrician or facilities representative must verify that there are two power drops
fed from separate redundant PDUs prior to turning on the VMAX3 array:
n
If both power drops to a bay are connected to the same PDU incorrectly, a DU
event will result during normal data center maintenance when the PDU is switched
off. The label on the power cables depicts the correct connection.
l
The electrician should pay particular attention to how each PDU receives power from
each UPS within the data center because it is possible to create a scenario where
turning off a UPS for maintenance could cause both power feeds to a single bay to be
turned off, creating a DU event.
l
The customer’s electrician should perform an AC verification test by turning off the
individual circuit breakers feeding each power zone within the bay, while the
Customer Engineer monitors the LED on the SPS modules to verify that power
redundancy has been achieved in each bay.
Customer input power cabling
59
Power cabling, cords and connectors
One PDU should never supply both power zone feeds to any one rack of equipment.
Power extension cords, connectors, and wiring
The following section illustrates a variety of extension cords that offer different interface
connector options. The selected cords are used to interface between the customer’s
power source and each EMC PDU connection.
The amount of cords needed is determined by the number of bays in the array and the
type of input power source used (single-phase or three-phase).

l
To ensure integrity of cables and connections, do not move racks that are secured
(bolted) together after installation.
l
A minimum of 42 inches (107 cm) front and 30 inches (76 cm) rear clearance is
required to provide adequate airflow and to allow for system service.
Site Planning Guide VMAX 100K, VMAX 200K, VMAX 400K, with HYPERMAX OS
Third party racking option
Customer rack requirements
The VMAX3 Family array components are shipped in a fully tested EMC rack and are
installed into the customer-supplied rack by EMC customer support engineers only. The
original shipping rack, when empty, is returned to EMC after the installation is complete.
To ensure successful installation and secure component placement, customer racks must
conform to the following requirements:
l
National Electrical Manufacturers Association (NEMA) standard for 19-inch cabinets.
l
Individual racks must be empty at the time of installation.
l
Threaded hole racks are not supported.
l
The cabinet must be in its final location with stabilizing (anti-tip) brackets installed.
l
A separate rack that supports a minimum 2000 lb/907 kg of weight must be provided
for each system bay.
Note
The customer must ensure floor load bearing requirements are met.
l
Components and cables installed in customer racks must conform to these
configuration rules:
n
Components and cables within a system bay can not be moved to available space
in different bay, or to a different location within the same bay.
n
System must be properly positioned in accordance with physical placement rules.
l
Internal depth of at least 43 inches (109 cm) with the front and rear doors closed.
This measurement is from the front surface of the NEMA rail to the rear door.
l
Round or square channel openings must support M5 screws that secure EMC rails
and components. Clip nuts are provided by EMC as required.
l
Non-dispersed rack-to-rack pass-through cable access at least 3 inches (7.6 cm) in
diameter must be available via side panels or horizontal through openings.
l
To ensure proper clearance and air flow to the array components, customer supplied
front doors and standard bezels, if used, must include a minimum of 2.5 inch (6.3
cm) clearance between the back surface of the door to the front surface of the vertical
NEMA rails.
Front and rear doors must also provide:
n
A minimum of 60% (evenly distributed) air perforation openings.
n
Appropriate access for service personnel, with no items that prevent front or rear
access to EMC components.
n
Exterior visibility of system LEDs.

Third party racking option
Third party racks with vertical PDUs— RPQ Required
Each VMAX3 Family system bay is powered by two redundant power distribution units
(PDUs), one PDU for each power zone. Rather than use the standard EMC horizontal PDU,
the customer can use vertical PDUs via RPQ. The general requirements for third party
racks with rear-facing or inward-facing PDUs are listed below.
l
Requirements for third party racks with vertical PDUs (inward-facing) on page 80
l
Requirements for third party racks with vertical PDUs (rear-facing) on page 78
General requirements for vertical PDUs within third party racks
In addition to meeting standard VMAX3 Family array power requirements, vertical PDUs
should abide by the following:
l
Both PDUs support AC-line input connectivity and provide outlets for every
component in the bay.
l
The PDU must be available in the wiring configuration that matches the customer
power supply.
Options include:
l
n
Single-phase
n
Three-phase Delta
n
Three-phase Wye
Each PDU should meet the following requirements:
n
At a minimum, a total of 24 power outlets must be provided.
The outlets are divided into six banks with each bank consisting of four IEC 60320
C13 individual AC outlets.
n
Each bank of outlets is connected to individual branch circuits that are protected
by a single two pole 20 Amp circuit breaker.
n
The PDU capacity should exceed the power requirements shown in the Power
Calculator for the specific max configuration.
If the customer requires power to be supplied from overhead, EMC recommends one of
the following:
l
Option 1: Replace the rear top cover of the bay with the ceiling routing top cover,
described in Overhead routing kit on page 84, which allows the power cables inside
the machine to be routed out through the top.
l
Option 2: "Drop" the power cables down the hinge side, to the bottom, and route
them inside the machine.
The cables should be dressed to allow all doors to open freely, minimize cable
congestion, and provide access to components within the system.

Best Practices AC power connections
Best practices overview for AC power connections
To assure fault tolerant power, external AC power must be supplied from independent,
customer-supplied, power distribution units (PDUs) as shown in Figure 29 on page 88.
NOTICE
For systems operating from three phase AC power, two independent and isolated AC
power sources are recommended for the two individual power zones in each rack of the
system. This provides for the highest level of redundancy and system availability. If
independent AC power is not available, there is a higher risk of data unavailability should
a power failure occur, including individual phase loss occurring in both power zones.
NOTICE
Before connecting external AC power to EMC bays, verify that the bays have been placed
in their final position as explained in the installation guide.

Selecting the proper AC power connection procedure
The EMC Customer Engineer must select the proper AC power connection procedure
There are three possible scenarios at the installation site regarding the connection of
customer AC power to the EMC array. The EMC Customer Engineer (CE) must select the
proper AC power connection procedure for the scenario.
1. Refer to table below which summarizes the three possible scenarios at the
installation site when you are about to connect external AC power to the EMC array.
2. Select the procedure that applies to your situation and follow the instructions for that
procedure.

Best Practices AC power connections
Procedure A, Task-3: Customer's electrician
NOTICE
This task is performed by the customer's electrician.
Procedure
1. Working with the EMC Customer Engineer, turn ON all the relevant circuit breakers in
customer-supplied PDU 2.
Verify that only power supply and/or SPS LEDs in power zone A are ON or flashing
green in every bay in the array.
Note
If all power supply and/or SPS LEDs in a bay are ON or flashing green, the bay is
incorrectly wired because the AC power to both EMC power zones is supplied by a
single PDU, that is, customer-supplied PDU 2. Wiring must be corrected before moving
on to the next step.
2. Turn OFF the relevant circuit breakers in customer-supplied PDU 2.
Verify that the power supply and/or SPS LEDs that turned green in the previous step
changed from green to OFF and/or flashing yellow. The yellow SPS lights flash for a
maximum of 5 minutes.
Note
Note that power supplies connected to an SPS continue to have green lights ON while
the SPS yellow light continues to flash indicating the SPS is providing on-battery
power.
3. Repeat step 1 and step 2 for power zone B and customer-supplied PDU 1.
4. Turn ON all the relevant circuit breakers in customer-supplied PDU 1 and customersupplied PDU 2.
5. Label the PDUs as described in PDU labels on page 98.

Procedure B: Verify and connect
Perform this procedure if the two conditions listed below are true:
l
Access to customer-supplied, labeled, power cables (beneath raised floor or
overhead).
l
The customer's electrician is not available at the installation site.
This procedure requires the EMC Customer Engineer to verify that the customer's
electrician has complied with power specifications. Once verified, the EMC Customer
Engineer makes the required power connections overhead or under the floor.
Procedure
1. Have the customer verify that their electrician has complied with power specifications
for voltage levels and redundancy. If the customer cannot verify this, provide them a
copy of Procedure A: Working with customer's electrician onsite on page 90. Inform
the customer that their array may prematurely shut down in the event of a site power
issue.
2. Access the labeled, power cables (beneath raised floor or overhead) to verify that the
customer-supplied power cables are properly labeled as shown in Figure 31 on page
91 and described in step 1 of Procedure A: Task-2: EMC Customer Engineer (CE) on
page 92.
3. Compare the numbers on the customer-supplied power cables for each EMC bay to
verify that power zone A and power zone B are powered by a different customersupplied PDU.
4. If power extension cables are required, connect them to power zone A and power zone
B in each bay.
5. Connect the customer-supplied power cables to EMC power zones as described in
step 3 of Procedure A: Task-2: EMC Customer Engineer (CE) on page 92.
6. Record the customer-supplied PDU information as described in step 1 of Procedure A:
Task-2: EMC Customer Engineer (CE) on page 92.
7. Label the PDUs as described in PDU labels on page 98.
Procedure B: Verify and connect
97
Best Practices AC power connections
Procedure C: Obtain customer verification
Perform this procedure if the three conditions listed below are true:
l
The customer-supplied PDU source cables are already plugged into the EMC PDU.
l
You have no access to the area below the raised floor.
l
The customer's electrician is not available at the installation site.
Procedure
1. Have the customer verify that their electrician has complied with power specifications
for voltage levels and redundancy. If the customer cannot verify this, provide them a
copy of Procedure A: Working with customer's electrician onsite on page 90. Inform
the customer that their array may prematurely shut down in the event of a site power
issue.
2. Record the customer-supplied PDU information (AC source voltage) as described in
step 1 of Procedure A: Task-1: Customer's electrician on page 91 and label the PDUs
as described in PDU labels on page 98.
PDU labels
Before applying labels to the PDUs, one of the following procedures must have been
completed:
l
Procedure A: Working with customer's electrician onsite on page 90
l
Procedure B: Verify and connect on page 97
l
Procedure C: Obtain customer verification on page 98
If necessary, see Selecting the proper AC power connection procedure on page 89 to
select the correct procedure.
