Important Safety Instructions
IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
This manual contains important instructions that should be followed during installation of your
Liebert NXL Battery Cabinet and accessories. Read this manual thoroughly, paying special attention
to the sections that apply to your installation, before working with the battery system. Retain this
manual for use by installing personnel.
! WARNING
Risk of electrical shock. Can cause personal injury and death.
Special safety precautions are required for procedures involving handling, installation and
maintenance of the UPS system. Only properly trained and qualified personnel wearing
appropriate personal protective equipment should be involved in installing the Liebert NXL
Battery system or preparing the system for installation.
Special care must be taken when working with the batteries associated with this equipment.
When connected together, the battery terminal voltage will exceed 400VDC and is potentially
lethal. Be constantly aware that the battery system contains high DC as well as AC voltages.
Check for voltage with AC and DC voltmeters before making contact.
Observe all DC safety precautions before working on or near the DC system.
Follow all battery safety precautions when installing, charging or servicing batteries. In
addition to the hazard of electric shock, gas produced by batteries can be explosive and
sulfuric acid can cause severe burns.
The following precautions must be observed when working on batteries:
•
•
•
•
•
•
Remove watches, rings and other metal objects.
Use tools with insulated handles.
Wear rubber gloves and boots.
Do not lay tools or metal parts on top of batteries.
Disconnect charging source prior to connecting or disconnecting battery terminals.
Determine whether the battery is grounded. If it is grounded, remove source of ground.
Contact with any part of a grounded battery can result in electrical shock. The likelihood of
such shock will be reduced if such grounds are removed during installation and maintenance.
If a battery leaks electrolyte, or is otherwise physically damaged, it must be replaced, stored
in a container resistant to sulfuric acid and disposed of in accordance with local regulations.
If electrolyte comes into contact with the skin, the affected area should be washed
immediately with water.
! WARNING
Risk of electric shock, explosive reaction, hazardous chemicals and fire. Can cause equipment
damage, personal injury and death.
Lead-acid batteries contain hazardous materials. Batteries must be handled, transported and
recycled or discarded in accordance with federal, state and local regulations. Because lead is a
toxic substance, lead-acid batteries must be recycled rather than discarded.
Do not dispose of a battery in a fire. The battery may explode.
Do not open or mutilate the battery or batteries. Released electrolyte is harmful to the skin
and eyes. It is toxic.
! WARNING
Risk of electric shock. Can cause personal injury and death.
In case of fire involving electrical equipment, use only carbon dioxide fire extinguishers or
those approved for use in fighting electrical fires.

Important Safety Instructions
! WARNING
Risk of heavy unit falling over. Can cause equipment damage, injury and death.
Exercise extreme care when handling battery cabinets to avoid equipment damage or injury
to personnel. The battery system cabinets weigh from 3760 to 8990 lb. (1706 to 4078kg).
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.
Slots at the base of the cabinets are intended for forklift use. Base slots will support the unit
only if the forks are completely beneath the unit.
! WARNING
Risk of electric shock. Can cause equipment damage, personal injury and death.
The area around the battery system must be kept free of puddles of water, excess moisture
and debris.
Observe all precautions in the Operation and Maintenance Manual, SL 25425, before as well
as during all installation and maintenance procedures. Observe all battery safety precautions
before working on or near the battery.
This equipment contains several circuits that are energized with high voltage. Only test
equipment designed for troubleshooting should be used. This is particularly true for
oscilloscopes. Always check with an AC and DC voltmeter to ensure safety before making
contact or using tools. Even when the power is turned Off, dangerously high potential electric
charges may exist at the capacitor banks and at the batteries.
All power and control wiring must be installed by a properly trained and qualified electrician.
All power and control wiring must comply with the NEC and applicable local codes.
When performing maintenance with any part of the equipment under power, service
personnel and test equipment must be standing on rubber mats. The service personnel must
wear insulating shoes for isolation from direct contact with the floor (earth ground).
One person should never work alone, even if all power is disconnected from the equipment. A
second person should be standing by to assist and to summon help in case of an accident.
NOTE
Materials sold hereunder cannot be used in the patient vicinity (e.g., use where UL, cUL or IEC
60601-1 is required). Medical applications such as invasive procedures and electrical life
support equipment are subject to additional terms and conditions.
NOTICE
This unit complies with the limits for a Class A digital device, pursuant to Part 15 Subpart J
of the FCC rules. These limits provide reasonable protection against harmful interference in a
commercial environment. This unit generates, uses and radiates radio frequency energy and,
if not installed and used in accordance with this instruction manual, may cause harmful
interference to radio communications. Operation of this unit in a residential area may cause
harmful interference that the user must correct at his own expense.

Preliminary Checks
Before installing the battery equipment, please carry out the following preliminary checks:
• Visually examine the 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 inside the main door.
• Verify that the battery 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
Battery Room
Batteries should be mounted in an environment where the temperature is consistent and even over
the whole battery. Temperature is a major factor in determining the battery life and capacity. Typical
battery manufacturer performance data are quoted for an operating temperature between 68 and
77°F (20 and 25°C). Operating above this range will reduce the battery life while operation below this
range will reduce the battery capacity.
Battery Temperature
In a normal installation, the battery temperature should be kept between 59 and 77°F (15°C and
25°C).
NOTE
Keep batteries away from main heat sources, main air inlets, etc.
1.3.2
Storage
Should the equipment not be installed immediately, it must be stored in a room for protection against
excessive humidity and heat sources (see Table 17).
NOTICE
Risk of deep discharge can cause permanent damage to batteries.
An unused battery must be recharged periodically as recommended by the battery
manufacturer.

1.4
Positioning
The cabinet is structurally designed to handle lifting from the base.
Power terminals, auxiliary terminals blocks and power switches are accessed from the front and top.
Removable panels on the top are secured to the chassis by screws. The door can be opened to give
access to the power connections bars, auxiliary terminal blocks and power isolators. The front door
can be opened 180° for easier service and more flexibility in installation.
1.4.1
Moving the Cabinets
The route to be travelled between the point of arrival and the unit’s installation location 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 cabinet weight is within the designated surface weight loading (kg/cm2) of any
handling equipment. See Table 17 for weight details.
Ensure that any lifting equipment used to move the battery equipment has sufficient lifting capacity.
Battery system equipment can be handled by a forklift or similar equipment.
Because the weight distribution in the cabinet is not symmetrical, use extreme care during handling
and transporting.
When moving the unit by forklift, care must be taken to protect the panels. Do not exceed a 15° tilt
with the forklift. Bottom structure will support the unit only if the forks are completely beneath the
unit.
Handling the unit with straps is not authorized.
! WARNING
Risk of heavy unit falling over. Can cause equipment damage, injury and death.
Exercise extreme care when handling battery cabinets. The battery system cabinets weigh
from 3760 to 8990 lb. (1706 to 4078kg).
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.
Slots at the base of the cabinets are intended for forklift use. Base slots will support the unit
only if the forks are completely beneath the unit.
The cabinet with top terminal batteries ships with extra bolts installed on the interior doors. Once the
cabinet is in the final position, these bolts can be removed. See Figure 1

1.4.2
Clearances
Liebert NXL has no ventilation grilles at either side or at the rear of the battery system equipment.
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 24" (610mm) between the top of the
cabinet and the ceiling of the room in which it is installed to permit adequate circulation of air coming
out of the unit and for service access.
1.4.3
Raised Floor Mounting
If the equipment is to be placed 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.
1.5
System Composition
A battery system can consist of a number of equipment cabinets, depending on the individual system
design requirements, e.g., Battery Cabinet, Junction Cabinet. Refer to 3.0 - Installation Drawings
for the positioning of the cabinets described below.

BATTERY INSTALLATION
2.1
Safety
Special care should be taken when working with the batteries associated with the Liebert NXL
Battery System equipment. When all the cells are connected together, the battery terminal voltage
will exceed 400V and is potentially lethal. A primary safety consideration is to install the battery
equipment in an isolated area, accessible only to properly trained and qualified maintenance
personnel.
! WARNING
Risk of electric shock. Can cause equipment damage, personal injury and death.
Hazardous battery voltage present behind covers. No user-serviceable parts are located
behind covers that require a tool for removal. Only properly trained and qualified service
personnel are authorized to remove such covers or perform installation or maintenance.
The following general battery safety precautions and warnings must be observed at all times:
• A battery can present risk of electric shock or burn from high short circuit currents.
• When connected in a string, the voltage will exceed 400VDC. This voltage is potentially
lethal. Always observe high-voltage precautions.
• Eye protection must be worn to prevent injury from accidental electrical arcs.
• Remove rings, watches, necklaces, bracelets and all other metal objects.
• Use only tools with insulated handles.
• Wear appropriate personal protective equipment when handling batteries.
• If a battery leaks electrolyte or is otherwise physically damaged, it should be placed in a
container resistant to wire and disposed of in accordance with local regulations.
• If electrolyte comes into contact with the skin, the affected area should be washed immediately with plenty of clean water.
• Batteries must always be disposed of according to local environmental laws.
• When replacing batteries, use the same number and type that were originally fitted.
• Disconnect charging source prior to connecting or disconnecting battery terminals.
• Determine if the battery is grounded. If it is grounded, remove source of ground. Contact
with any part of a grounded battery can result in electrical shock.
• Battery support tray must be used whenever a battery tray is being pulled out.
2.2

Liebert® NXL™ Battery System
Battery Installation
2.6
Alber Monitoring System—Optional
The Liebert matching battery cabinet allows installing an optional Alber battery monitoring system
in the cabinet. The Alber battery monitoring continuously checks all critical battery parameters, such
as cell voltage, overall string voltage, current and temperature. Automatic periodic tests of internal
resistance of each battery will verify the battery’s operating integrity. Additional capabilities include
automatic internal DC resistance tests and trend analysis providing the ability to analyze
performance and aid in troubleshooting.
The Alber monitoring system is installed inside the battery cabinet (see Figure 37). The monitoring
system requires approximately 0.5A, single-phase power.
This power can come from the output of the UPS the battery cabinet is suppling (see Figure 37).
The Alber monitoring system consists of a Controller Module and Data Collector Module (see
Figure 35). One Controller Module can monitor up to six battery cabinets with a Data Collector
Module installed. The battery cabinet with the Controller Module (Battery Cabinet #1) must be
installed in the position closest to the UPS.
For details about operating the Alber system, see the Alber Monitoring System manual, available at
the Liebert Web Site, www.liebert.com
2.7
External Battery Room Temperature Sensor—Optional
For systems that do not use Liebert NXL Battery Cabinets, an optional temperature sensor can be
installed to monitor the ambient room temperature. This sensor is connected to the BIB board (see
Figure 7). This sensor will allow the Liebert NXL UPS to perform temperature compensation
charging.
