1.0 MECHANICAL INSTALLATION
1.1 Introduction
This following section describes the requirements that must be taken into account when planning the
positioning and cabling of the Liebert NXL battery equipment.
This chapter is a guide to general procedures and practices that should be observed by the installing
engineer. The particular conditions of each site will determine the applicability of such procedures.
NOTICE
Do not apply electrical power to the UPS equipment before the arrival of the commissioning
engineer.
1.2 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 on the back of 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.
Mechanical Installation
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 20 and
25°C (68 and 77°F). 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 15°C and 25°C
(59 and 77°F).
NOTE
Keep batteries away from main heat sources or 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 or heat sources (see Table 7).
NOTICE
An unused battery must be recharged periodically as recommended by the battery
manufacturer.
3
1.4 Positioning
The cabinet is structurally designed to handle lifting from the base.
Access to the power terminals, auxiliary terminals blocks and power switches is 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 at 180° for better service and more flexibility in installations.
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 cabinet weight is within the designated surface weight loading (kg/cm
dling equipment. See Table 4 for weight details.
Ensure any lifting equipment used in moving the battery equipment has sufficient lifting capacity.
Battery system equipment can be handled by means of a forklift or similar equipment.
Because the weight distribution in the cabinet is uneven, use extreme care during handling and
transporting.
Mechanical Installation

2.4 Power Connection
Depending on the site layout, the Battery cabinets can be cabled several ways. See Figures 2
through 8.
2.4.1 Connected System
For cabinets that have been ordered as connected (battery cabinets will bolt to each other), the positive and negative busbars can be bolted together using the supplied bus bar connector extensions. See
Figure 24
2.4.2 Stand-Alone System
For cabinets that are ordered as stand-alone, customer must supply all the interconnecting cables
and hardware. See Table 15 for current ratings and recommended cable sizes.
2.4.3 Attached/Detached System
For battery cabinets that are connecting to a Liebert NXL UPS, Liebert NXL MBD cabinet or Liebert
NXL Junction cabinet (see Figures 2 through 6), cables will run from the positive and negative busbars of the adjacent battery cabinet to the positive and negative DC connections of UPS, MBD or
Junction cabinet.
For attached systems (the cabinets bolt to each other) the cables can run internal to the cabinets and
will be supplied.
For detached systems (the cabinets do not bolt to each other), the cables must be run outside the cabinets. The customer must supply all the interconnecting cables and hardware. See Table 15 for current ratings and recommended cable sizes.
10
2.4.4 MBD voltage sense leads
For ease of installation, the power cables from the battery cabinets can be installed on either the top
or bottom breaker busbars (depending if top or bottom entry is used). The voltage sense leads need to
be connected to the busbars on the input of the circuit breaker (busbars that have the cables from the
battery system connected.) See Figure 22.
WARNING
!
Risk of electric shock. Can cause equipment damage, personal injury or death.
Hazardous battery voltage may be present on busbar. Install battery voltage sense leads
before connecting the positive and negative power cables.
2.4.5 Grounding
For cabinets that have been ordered as connected or attached, the ground cables and hardware will be
supplied. See Figure 25 for location of cabinet-to-cabinet grounding.
For cabinets ordered as detached or stand-alone, customer must supply the cables and hardware. See
Table 15 for current ratings and recommended cable sizes.
2.5 Control Connection
Each Liebert NXL Battery Cabinet and Liebert NXL Module Battery Disconnect (MBD) contains a
Battery Interface Board (BIB). See 3.0 - Installation Drawings. All cabinets in a system must have
their Battery Interface boards connected in series. See Figure 14 for battery cabinet details and
Figure 16 for MBD details.
Battery Installation
NOTE
Care must be taken to route the control cables away from high voltage cables or busbars.

NOTICE
Risk of improper installation. Can cause equipment damage.
During system commissioning, Liebert Services will set the jumpers on the EIB and the BIB.
If another battery cabinet is added to the system after commissioning, it is imperative that
Liebert Services reset the jumpers on the EIB board and the BIB board.
13
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 33). 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 33).
The Alber monitoring system consists of a Controller Module and Data Collector Module (see
Figure 31). One Controller Module can monitor up to six (6) battery cabinets with a Data Collector
Module installed. The Battery cabinet with the Controller Module (battery cabinet #1) must be install
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, but have an MBD connected to a battery
string, an optional temperature sensor can be installed to monitor the ambient room temperature.
This sensor is connected to the BIB in the MBD cabinet (see Figure 11). This sensor will allow the
Liebert NXL UPS to perform temperature compensation charging.

The recommendations in this table are guidelines only and are superseded by local regulations and codes of practice where applicable:
1. Take special care when determining the size of the neutral cable, because current circulating on the neutral cable may be greater than
2. The ground conductor should be sized according to the fault rating, cable lengths, type of protection, etc. The ground cable connecting
3. Consideration should be given to the use of paralleled smaller cables for heavy currents, as this can ease installation considerably.
4. When laying the power cables, do not form coils. Coiling power cables increases the likelihood of electromagnetic interference.
