| Liebert® EXL™ 625-1100kVA Installation Manual | Rev. 3 | 02/17 5
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 13).
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 Storing the UPS and Batteries for Delayed Installation
If the Liebert EXL system will not be installed immediately, it must be stored indoors in a clean, dry and cool
location (see Environmental Parameters in Table 13). If the UPS includes batteries, either internally or in a
battery cabinet, the batteries’ requirements will dictate the storage conditions. Batteries should be unpacked,
installed and charged as soon as possible after delivery.
NOTICE
Risk of failure to properly charge batteries. Can cause permanent damage to batteries and void the warranty.
Batteries will self-discharge during storage. Batteries must be recharged as recommended by the battery manufacturer.
A notice of “Charge Before Date” is affixed to each unit that has batteries inside. The “Charge Before Date” is calculated
based on the batteries being stored at 77°F (25°C). Storage at a higher temperature will increase the rate of self-discharge,
requiring earlier recharge. Consult the battery manufacturer on how to determine when the batteries need to be
recharged.
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.
NOTE
The UPS is suitable for mounting on concrete or other non-combustible surface only.
NOTE
The UPS must be placed on a non-combustible surface suitable to support the weight of the unit.
Vertiv
| Liebert® EXL™ 625-1100kVA Installation Manual | Rev. 3 | 02/17 6
1.4.1 Moving the Cabinets
The route to be traveled 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/in
2
) of any handling equipment.
For weight details, see Table 13.
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.
1.4.2 Clearances
The Liebert EXL 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 permit 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.
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 Figure 20 to design this pedestal.
1.4.4 Kick Plate Installation
If the unit is to be installed in a position that does not permit access to rear kick plates, then the kick plates
should be installed before the unit is placed in its final position.
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 weighs up to 8095 lb. (3672 kg).
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.
AVERTISSEMENT
Le centre de gravité élevé de l’appareil présente un risque de renversement. Une mauvaise manutention
peut entraîner des dommages matériels, des blessures et même la mort.
En raison de la distribution inégale du poids de l’armoire, vous devez faire preuve d’extrême prudence lors
de sa manipulation et de son transport. Faites preuve d’une extrême prudence lors de la manutention des
armoires ASC afin d’éviter de les endommager ou de blesser le personnel.
Le module ASC pèse jusqu’à 3 672 kg (8 095 lb).
Identifiez les symboles de centre de gravité et déterminez le poids de l’appareil avant de manipuler
chaque armoire. Testez le levage et l’équilibre les armoires avant de transporter l’appareil. Maintenez en
tout temps l'inclinaison verticale minimale.

1.4.5 Special Considerations for 1+N Parallel Systems
Design the grounding configuration of the system before finalizing module placement See 2.7 - Grounding.
The cabling impedance must be carefully controlled to ensure good load-sharing. Impedance mismatch may
cause an overload on one module in a 1+N system, triggering a shutdown and loss of power to the connected
load. Mismatched cable impedance is amplified when a 1+N system is operating on bypass because the power on
the bypass path is not controlled.
The Liebert 1+N UPS module is supplied with a sharing inductor to minimize the impact of cable impedance
mismatch. An impedance mismatch may be further minimized by controlling the wiring length of each unit. The
design and the layout of the UPS system and associated panels and cabling must be designed to ensure that
cable lengths and impedances are closely matched.
Table 1 shows bypass load sharing when the cabling length is varied for three 800kVA UPS modules powering
the load via their static bypass switches.
For further information about matching cable impedances or refer to “Performance Improvements with Sharing
Inductors in Distributed Static Switch UPS Systems” found at the Liebert EXL section of Liebert’s Web site,
www.liebert.com; or contact Vertiv

1.4.6 Special Considerations for Remote Breaker
The voltage sense cable for the rectifier input breaker must accommodate the pre-charge circuit for the UPS,
sized to 60A fuses at the sense location (see Figure 11). Breakers must be sized appropriately for the overload
curves as shown in the operation and maintenance manual, SL-26030, available at Lieberts Web site,
www.liebert.com
1.5 SYSTEM COMPOSITION
A UPS system can include a number of equipment cabinets, depending on the system design: (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 Figures 1 through 6.
1.6 CABLE ENTRY
Cables can enter the UPS cabinet from bottom or top into the Input/Output (I/O) of the unit; see the figures in
4.0 - Installation Drawings.
1.7 CABLE ROUTING
Per NEC 300.20 (NEC 2014 or equivalent), all phase conductors and ground conductors must be grouped
together when they are installed in ferrous enclosures or go through ferrous material. This is to avoid heating
from induction currents.

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 31, 32 and 33 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 14 through 17, 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.
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 et des
lunettes de sécurité adéquats doivent se charger d’installer le système ASC ou de le préparer pour
l’installation.
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 voltage drop of 2VDC is permissible at the current ratings given in
Table 17.
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
Vertiv 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.
AVERTISSEMENT
Risque de décharge électrique pouvant causer des blessures graves, voire mortelles.
Avant de procéder au câblage du système ASC, assurez-vous que vous êtes au courant de l’emplacement
et du fonctionnement des isolateurs externes qui raccordent l’alimentation d’entrée ou de dérivation au
panneau de distribution électrique.
Vérifiez que ces raccords sont isolés électriquement et installez tous les panneaux d’avertissement
nécessaires pour empêcher leur utilisation accidentelle.
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 Vertiv. See the back page of this
manual for contact information.
