Introduction
This section describes the requirements that must be taken into account when planning the
positioning and cabling of the Liebert NXL uninterruptible power supply and related equipment.
This chapter is a guide to general procedures and practices that should be observed by the installing
personnel. The particular conditions of each site will determine the applicability of such procedures.
! WARNING
Risk of electrical shock. Can cause injury or death.
Special care must be taken when working with the batteries associated with this equipment.
When they are connected together, the battery terminal voltage will exceed 400VDC and is
potentially lethal.
NOTE
All equipment not referred to in this manual is shipped with details of its own mechanical and
electrical installation.
NOTICE
Three-phase input supply required.
The standard Liebert NXL UPS is suitable for connection to three-phase, four-wire (+ Earth)
TN-C, TN-S, IT-G or IT-IG, or three-phase, three-wire plus ground IT-UG.
If the unit is used with an IT power system, a 4-pole disconnect device must be included as
part of building installation.
NOTICE
Do not apply electrical power to the UPS equipment before the arrival of the commissioning
engineer.
1.2
Preliminary Checks
Before installing the UPS, please carry out the following preliminary checks:
• Visually examine the UPS equipment for transit damage, both internally and externally. Report
any damage to the shipper immediately.
• Verify that the correct equipment is being installed. The equipment supplied has an identification
tag on the interior doors reporting the type, size and main calibration parameters of the UPS.
• Verify that the UPS room satisfies the environmental conditions stipulated in the equipment
specification, paying particular attention to the ambient temperature and air exchange system.
1.3
Environmental Considerations
1.3.1
UPS Room
The UPS module is intended for indoor installation and should be located in a cool, dry, clean-air
environment with adequate ventilation to keep the ambient temperature within the specified
operating range (see Environmental Parameters in Table 15).
The Liebert NXL UPS is cooled with the aid of internal fans. To permit air to enter and exit and
prevent overheating or malfunctioning, do not cover the ventilation openings.
NOTE
To ensure proper airflow, the unit must be installed only on a solid surface made of a
non-combustible material, such as concrete.
The Liebert NXL UPS is equipped with air filters located behind the front doors. A schedule for
inspection of the air filters is required. The period between inspections will depend upon
environmental conditions.
When bottom entry is used, the conduit plate must be installed.
NOTE
The UPS is suitable for mounting on concrete or other non-combustible surface only.

Liebert® NXL™
Mechanical Installation
1.3.2
Storage
Should the equipment not be installed immediately, it must be stored in a room for protection against
excessive humidity and/or heat sources (see Environmental Parameters in Table 15).
1.4
Positioning
The cabinet is structurally designed to handle lifting from the base.
Access to the power terminals, auxiliary terminal blocks and power switches is from the front.
The door can be opened to give access to the power connection bars, auxiliary terminal blocks and
power isolators. Front door can be opened at 180 degrees, and interior doors can be removed for more
flexibility in installations.
NOTE
The UPS must be placed a solid surface. There must be no openings in the surface except those
required for conduit landing areas. All provided kick plates must be installed.
1.4.1
Moving the Cabinets
The route to be travelled between the point of arrival and the unit’s position must be planned to make
sure that all passages are wide enough for the unit and that floors are capable of supporting its
weight (for instance, check that doorways, lifts, ramps, etc. are adequate and that there are no
impassable corners or changes in the level of corridors).
Ensure that the UPS weight is within the designated surface weight loading (kg/cm2) of any handling
equipment. For weight details, see Table 15.
The UPS can be handled with a forklift or similar equipment. Ensure any lifting equipment used in
moving the UPS cabinet has sufficient lifting capacity. When moving the unit by forklift, care must be
taken to protect the panels. Do not exceed a 15-degree tilt with the forklift. Bottom structure will
support the unit only if the forks are completely beneath the unit.
Handling with straps is not authorized.
! WARNING
Risk of heavy unit falling over. Improper handling can cause equipment damage, injury or
death.
Because the weight distribution in the cabinet is uneven, use extreme care while handling
and transporting. Take extreme care when handling UPS cabinets to avoid equipment
damage or injury to personnel.
The UPS module weight is up to 23,000lb (10,433kg).
Locate center of gravity symbols
and determine unit weight before handling each
cabinet. Test lift and balance the cabinets before transporting. Maintain minimum tilt from
vertical at all times.
NOTICE
Risk of improper lifting. Can cause damage to front and rear panels.
Remove the front and rear panels before lifting the 1100-1125kVA Liebert NXL unit. Failure
to remove these panels may cause them to be damaged when the UPS is lifted.
1.4.2
Clearances
The Liebert NXL has no ventilation grilles at either side or at the rear of the UPS. Clearance around
the front of the equipment should be sufficient to enable free passage of personnel with the doors fully
opened. It is important to leave a distance of 24in (610mm) between the top of the UPS and any
overhead obstacles to allow the module to be serviced and to permit adequate circulation of air coming
out of the unit.
Liebert® NXL™

Mechanical Installation
1.4.3
Raised-Floor Installations
If the equipment is to be located on a raised floor, it should be mounted on a pedestal suitably
designed to accept the equipment point loading. Refer to the base view to design this pedestal. The top
of the pedestal must be solid.
NOTE
The UPS must be placed on a solid surface. There must be no openings in the surface except
those required for conduit landing areas. All provided kick plates must be installed.
1.4.4
Kick Plate Installation
Kick plates must be installed. If the unit is to be installed in a position that does not permit access to
rear kick plates, then the kick plates must be installed before the unit is placed in its final position.
1.4.5
Special Considerations for 1+N Parallel Systems
Consider the grounding configuration of your system before finalizing module placement See 2.6 Configuring Neutral and Ground Connections.
Emerson Network Power recommends matching the impedance in the bypass path of paralleled
systems as closely as possible.
The impedance mismatch can be minimized by controlling the wiring length of each unit. The design
and the layout of the UPS system and associated panels and cabling should be examined closely to
ensure that cable lengths and impedances are closely matched. The Liebert 1+N UPS module is
supplied with a sharing reactor to minimize the impact of cable impedance mismatch.
The cabling impedance must be carefully controlled to ensure good bypass current sharing.
For Liebert NXL Systems, the cabling impedances must be within 10% from maximum to minimum.
If the cabling impedances need to be greater than 10%, contact your Emerson representative to
calculate whether the system will result in an overload condition when operating on bypass.
When bringing the 1+N system online for the first time or after removing one unit, Emerson
recommends checking the bypass current mismatch. To check the bypass current mismatch:
1. Place a load on the bypass of each UPS module.
2. View the output current of each unit.
The accuracy of the currents displayed on the UPS module is sufficient for this check. If the
mismatch is greater than 10%, the bypass impedances must be balanced or the load must be
limited to less than the maximum rating.
1.5
System Composition
A UPS system can comprise a number of equipment cabinets, depending on the individual system
design requirements: e.g., UPS cabinet, battery cabinet, maintenance bypass cabinet. In general, all
the cabinets used in a particular installation are of the same height. Refer to the drawings provided in
4.0 - Installation Drawings for the positioning of the cabinets as shown in Figure 1.

UPS ELECTRICAL INSTALLATION
This chapter provides guidelines for qualified installers who must have knowledge of local wiring
practices pertaining to the equipment to be installed.
! WARNING
Risk of electrical shock. Can cause injury or death.
The UPS contains high DC as well as AC voltages. Check for voltage with both AC and DC
voltmeters before working within the UPS.
Only properly trained and qualified personnel wearing appropriate safety headgear, gloves,
shoes and glasses should be involved in installing the UPS or preparing the UPS for
installation.
2.1
External Protective Devices
For safety, it is necessary to install circuit breakers in the input AC supply and external battery
system. Given that every installation has its own characteristics, this section provides guidelines for
qualified installation personnel with knowledge of operating practices, regulatory standards and the
equipment to be installed.
External overcurrent protection must be provided. See Figures 66, 67 and 68 for overload capacity.
2.2
Power Cables
The UPS requires both power and control cabling. All control cables, whether shielded or not, should
be run separately from the power cables in metal conduits or metal ducts that are electrically bonded
to the metalwork of the cabinets to which they are connected.
The cable design must comply with the voltages and currents in Tables 16 through 19, follow local
wiring practices and take into consideration the environmental conditions (temperature and physical
support media), room temperature and conditions of installation of the cable and system’s overload
capacity (see 5.0 - Specifications).
! WARNING
Risk of electrical shock. Can cause injury or death.
Before cabling the UPS, ensure that you are aware of the location and operation of the
external isolators that connect the UPS input/bypass supply to the power distribution panel.
Check that these supplies are electrically isolated, and post any necessary warning signs to
prevent their inadvertent operation.
When sizing battery cables, a maximum volt drop of 2VDC is permissible at the current ratings given
in Table 19.
The following are guidelines only and are superseded by local regulations and codes of practice where
applicable:
• Take special care when determining the size of the neutral cable (grounded conductor), because
current circulating on the neutral cable may be greater than nominal current in the case of nonlinear loads. Refer to the values in Table 15.
• The grounding conductor should be sized according to the fault rating, cable lengths, type of protection, etc. The grounding cable connecting the UPS to the main ground system must follow the
most direct route possible.
• Consideration should be given to the use of paralleled smaller cables for heavy currents, as this
can ease installation considerably.
• AC and DC cables must be run in conduits according to local codes, national codes and standard
best practices. This will prevent creation of excess EMI fields.

UPS Electrical Installation
2.3
Sizing the Input Breaker feeding a Liebert NXL UPS
Nominal input current (considered continuous) is based on full-rated output load. Maximum current
includes nominal input current and maximum battery recharge current (considered noncontinuous).
Continuous and noncontinuous current are defined in the NEC. The Rectifier Input Feed Breaker
must be set to withstand the Liebert NXL transformer inrush of up to eight times the nominal
current.
Maximum input current is controlled by the current limit setting, which is adjustable. Values shown
are for maximum current limit. If a smaller input feed breaker is used, the input current limit can be
adjusted; see your Emerson representative for more information. The input current limit should not
be set less than 105% of the current needed to support the inverter at full load for normal operation.
This results in sufficient power to recharge the battery in a reasonable time and to operate over the
published input voltage range.
2.3.1
Power Cable Connection Procedure
The rectifier input, bypass, output and battery power cables (all require lug-type terminations) are
connected to busbars in the I/O sections (refer to 4.0 - Installation Drawings).
Equipment Ground
The equipment ground busbar is in the I/O sections as shown in (refer to 4.0 - Installation
Drawings). The grounding conductor must be connected to the ground busbar and bonded to each
cabinet in the system.
All cabinets and cabling should be grounded in accordance with local regulations.
NOTE
Proper grounding reduces problems in systems caused by electromagnetic interference.
! WARNING
Failure to follow adequate grounding procedures can result in electric shock hazard to
personnel, or the risk of fire, should a ground fault occur.
All operations described in this section must be performed by properly trained and qualified
electricians or technical personnel. If any difficulties are encountered, contact Emerson
Network Power. See the back page of this manual for contact information.
The grounding and neutral bonding arrangement must be in accordance with local and
national codes of practice.
Once the equipment has been positioned and secured, connect the power cables as described below
(refer to the appropriate cable connection drawing in 4.0 - Installation Drawings):
1. Verify that the UPS equipment is isolated from its external power source and all the UPS power
isolators are open. Check that these supplies are electrically isolated and post any necessary
warning signs to prevent their inadvertent operation.
2. Open exterior and interior panels on the front of the I/O sections.
3. Connect the ground and any necessary main bonding jumper to the equipment ground busbar
located in the I/O sections.
4. Make power connections and tighten the connections to the proper torque.
Ensure correct phase rotation.
! WARNING
Risk of electrical shock. Can cause injury or death.
If the load equipment will not be ready to accept power on the arrival of the commissioning
engineer, ensure that the system output cables are safely isolated at their termination.
! WARNING
Risk of electrical shock. Can cause injury or death.
When connecting the cables between the battery extremities to the circuit breaker, always
connect the circuit breaker end of the cable first.

Belden 810x or Belden 89901 cables are the only approved cables.
Belden 89901 cable can be used for underground installations.
If using multiple parallel cables for each run, all cables must be run in the same conduit.
Each cable group should be run in a separate grounded conduit to ensure redundancy.
The maximum lengths must include all the parallel cables from the first module to the last module. The primary and redundant
cable lengths can be counted separately.
6. The ground pins on the Inter-Module Communication Board (Pins 7 and 14) are connected together on the board. If using
cable with only one (1) drain wire, then connect to the ground to Pin 7.
7. Care must be taken so drain wire does not touch any other component in module.
8. Attach control wires to side of control door where Inter-Module Board (IMC) is attached. Do not run wires across IMC board.

Configuring Neutral and Ground Connections
Improper grounding is the largest single cause of UPS installation and startup problems. Grounding
techniques vary significantly from site to site, depending on several factors.
Proper grounding should be based on the appropriate NEC sections, but safe and proper equipment
operation requires further enhancements. The following pages detail recommendations for grounding
various system configurations to ensure optimal UPS system performance.
NOTE
These UPS modules are equipped with input isolation transformers. However, these
transformers have no effect upon any system grounding considerations. These modules will be
grounded exactly as shown in Figures 10 through 13.
! CAUTION
The UPS ground lug must be solidly connected to the service entrance ground by an
appropriately sized wire conductor per the NEC. Each conduit or raceway containing phase
conductors must also contain a ground wire, both for UPS input and output, which are solidly
connected to the ground terminal at each termination point. Conduit-based grounding
systems tend to degrade over time. Therefore, using conduit as a grounding conductor for UPS
applications may degrade UPS performance and cause improper UPS operation.
2.6.1
Four-Wire Input connections
The UPS module bypass input is connected to a solidly grounded source. In this configuration, the
UPS module is not considered a separately derived source. The UPS module output neutral is solidly
connected to the bypass source neutral, which is bonded to the grounding conductor at the source
equipment.

Three-Wire Input connections
This configuration must NOT be used when single-phase loads are directly connected to the UPS. The
UPS output is considered a separately derived source. The UPS module neutral is bonded to the UPS
ground and connected to a local grounding electrode in accordance with the NEC. Please note that
whenever the UPS module transfers to or from bypass, two AC sources (UPS output and bypass) are
briefly connected together and circulating current must flow. In this configuration, the current flows
through the ground path, possibly tripping ground fault interrupters (GFIs) and distorting the output
voltage waveform. Proper adjustment of ground fault interrupters is necessary to avoid unwanted
tripping. The time delay should be set to at least 0.2 seconds to prevent tripping when the UPS
performs a transfer or retransfer operation.
CAUTION
Failure to set the ground fault interrupters properly could cause loss of power to the critical
load.

Preferred Grounding Configuration, Battery Systems
Open-rack battery systems, depending on local code requirements and customer preference, are
normally:
• Floating (ungrounded)
OR
• Center-tapped and floating
Battery cabinet systems must be connected as floating (ungrounded) systems.
Center-tapped or grounded battery systems are not possible with battery cabinet systems.
Whether the battery system is open-rack or cabinet, the metal rack parts or cabinet must be grounded
to the UPS module ground bus.
2.6.4
Multi-Module Systems
For both N+1 and 1+N systems, the neutrals of all UPS modules in the system must be connected
together inside the switchgear or parallel cabinet. The neutral conductors must be rated for 20% of
phase conductor current minimum. Site and load conditions will determine if larger neutrals are
required.
For Multi-Module systems using a 3-wire bypass, the Neutral-Ground bond must be made at the
common neutral connection point in the switchgear or parallel cabinet.
2.6.5
High-Resistance Ground Systems
The Liebert NXL is compatible with high-resistance ground systems. See your local Emerson
representative for details.

Notes on Tables
1. Nominal input current (considered continuous) is based on full-rated output load. Maximum
current includes nominal input current and maximum battery recharge current (considered
noncontinuous). Continuous and noncontinuous current are defined in NEC 100.
2. Maximum input current is controlled by the current limit setting, which is adjustable. Values
shown are for maximum current limit. If a smaller input feed breaker is used, the input current
limit can be adjusted; see your Emerson representative for more information.
3. The Rectifier Input Feed Breaker must be set to withstand the Liebert NXL transformer inrush of
up to eight times the nominal current.
4. For breaker coordination while the module is overloaded, see the current versus time values on
the overload curves.
5. Nominal battery voltage is shown at 2.0 volts/cell.

1. Recommended cable sizes are 167°F (75°C) (THW) wire at 86°F (30°C) ambient. Unless otherwise noted, use copper or aluminum
conductors suitable for at least 75°C.
2. For continuous operation not at 86°F (30°C), Emerson recommends that the site planner choose the appropriate cable type based on
the particular installation requirements.
3. Conduit size is based on FMC type conduit with 2 neutral conductors rated at 200% of phase.
