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 7).
The Liebert eXL 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.
The Liebert eXL 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.
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 7).
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 to 90 degrees, and interior doors can be removed for 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 UPS weight is within the designated surface weight loading (lb/in2) of any handling
equipment. For weight details, see Table 7.
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

2.0 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.
2.1 External Protective Devices
For safety, circuit breakers must be installed 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 15,16 and 17 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 8 through 11, 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).
When sizing battery cables, a maximum voltage drop of 2VDC is permissible at the current ratings
given in Table 11.
!
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.
!
AVERTISSEMENT
Risque de décharge électrique pouvant causer des blessures graves, voire mortelles.
Le système ASC contient des tensions c.c. et c.a. élevées. Vérifiez les tensions au moyen de
voltmètres c.a. et c.c. avant d’utiliser le système ASC.
Seuls des employés qualifiés et dûment formés portant un casque, des gants, des chaussures

®eXL™
The following are guidelines only and are superseded by local regulations and codes of practice where
applicable:
• 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.
2.3 Sizing the Input Breaker Feeding a Liebert eXL 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.
Maximum input current is controlled by the current limit setting, which is adjustable. Values shown
are for default current limit of 125%. 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 busbars are in the I/O sections (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.
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.
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.
!
AVERTISSEMENT

2.5 Grounding
2.5.1 Three-Wire Input connections
This module must NOT be used when single-phase loads are directly connected to the UPS. 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 and may trip ground fault interrupters (GFI’s), distorting the output voltage
waveform. Proper adjustment of GFI’s 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.
NOTICE
Failure to set the ground fault interrupters properly could cause loss of power to the critical
load.
2.5.2 High Resistance Grounding
Contact your Emerson®representative or the factory to determine whether the Liebert eXL is
compatible with the specific type of HRG system involved.
2.5.3 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.
