1 IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
This manual contains important instructions that should be followed during installation of your Liebert®
EXLS1™ UPS. Read this manual thoroughly, paying special attention to the sections that apply to your
installation, before working with the UPS. Retain this manual for use by installing personnel.
WARNING! Risk of electrical shock. Can cause personal injury or death. This UPS has several
circuits that are energized with high DC as well as AC voltages. Check for voltage with both AC
and DC voltmeters before working within the UPS. Check for voltage with both AC and DC
voltmeters before making contact. 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. When performing maintenance on any part of the
equipment under power, service personnel and test equipment should be standing on rubber
mats. In case of fire involving electrical equipment, use only carbon dioxide fire extinguishers or
those approved for use in fighting electrical fires.
WARNING! Extreme caution is required when performing installation and maintenance. Special
safety precautions are required for procedures involving handling, installation and maintenance
of the UPS system. Observe all safety precautions in this manual before handling or installing
the UPS system. Observe all precautions in the Operation and Maintenance Manual, SL-26090,
before as well as during performance of all maintenance procedures. Observe all DC safety
precautions before working on or near the DC system.
WARNING! Risk of heavy unit falling over. Improper handling can cause equipment damage,
injury or death. Exercise extreme care when handling UPS cabinets to avoid equipment damage
or injury to personnel. Locate the center of gravity symbols and determine the unit’s weight
before handling each cabinet. Test lift and balance the cabinets before transporting them.
Maintain minimum tilt from vertical at all times. Slots at the base of the module cabinets are
intended for forklift use. Base slots will support the unit only if the forks are completely
beneath the unit. Read all of the following instructions before attempting to move, lift or
remove packaging from the unit, or to prepare the unit for installation. The UPS module weighs
up to 4667 lb. (2117 kg).

WARNING! Risk of electrical shock and fire. Can cause equipment damage, personal injury or
death. Only normal safety precautions are necessary under typical operation and with all UPS
doors closed. The area around the UPS system should be kept free of puddles of water, excess
moisture and debris. Only test equipment that is 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 with the UPS or using tools to work on any UPS component.
Dangerously high potential electric charges may exist at the capacitor banks and at the DC
connections even when input power is turned Off. All wiring must be installed by a properly
trained and qualified electrician. All power and control wiring must comply with all applicable
national, state and local codes. 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.

2 MECHANICAL INSTALLATION
2.1 Pre-installation Planning
This section describes the requirements that must be taken into account when planning the positioning
and cabling of the UPS and related equipment.
Installing personnel should observer these general procedures and practices. 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 the batteries are connected
together, the battery-terminal voltage will exceed 400VDC 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
Risk of incorrect input power connection. Can cause equipment damage.
The standard Liebert® EXL S1™ Installer Guide UPS is suitable for connection to 60-Hz,
3-phase, 3-wire-plus-ground input power.
NOTE: Do not apply electrical power to the UPS equipment before the arrival of the commissioning
engineer. Connecting power before the commissioning engineer determines the system is properly
installed may void the warranty.
2.2 Preliminary Checks
Before installing the UPS, carry out the following preliminary checks:
•Visually examine the UPS equipment for transit damage, both internally and externally. Report
any damage to the shipper and to your Vertiv representative immediately.
•Verify that the correct equipment is being installed. The equipment supplied has an
identification tag on the interior doors stating 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.
2.3 Environmental Considerations
2.3.1 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 Table 5.3 on page42).
The UPS is cooled with the aid of internal fans. Do not cover the ventilation openings. Cooling air must
enter and exit the cabinets freely to prevent overheating or malfunctioning.
2 Mechanical Installation 3

The UPS is equipped with air filters behind the front doors. A schedule for inspection of the air filters is
required. The period between inspections will depend upon environmental conditions.
When using bottom-entry, the conduit plate must be installed.
NOTE: The UPS must be installed on concrete or other non-combustible surface.
NOTICE
There is a potential risk to the operational integrity of an installed UPS system by the presence
of foreign material inside or in the vicinity of the UPS module.
This risk is especially high if conductive materials find their way inside the UPS module.
The risk potentially involves damage to the installed UPS equipment and subsequent
degradation or loss of power to the connected critical site load.
Vertiv applies the highest safety standards in equipment design to ensure that no live parts
are exposed to external contact, and also to ensure that the equipment is protected against
the introduction of foreign bodies during operation. However, it is not possible for Vertiv. to
ensure that foreign bodies will not be introduced during on-site installation, or when the UPS
doors and covers are open and the electrical terminals are exposed to allow power line
connections to be made by the electrical contractor/installer.
To prevent major disruption to site operations and risk to property and personnel, including
the possibility of a fatality, each site’s facility manager or construction manager must prevent
foreign bodies from being introduced into the UPS module.
All UPS modules are thoroughly inspected by Vertiv engineers before being placed into service
and testing on-site. However, the person responsible for the site must ensure that the UPS
module and the immediate surroundings are kept clean and free from any possible conductive
material such as metal foil, food wrappers, cable shields, washers and other hardware, scrap
metal and dust.
If the UPS system is shut-down after placement into service and testing are completed, the
UPS room must be kept clean to avoid the possibility (during restart) of the considerable
volume of air-flow produced by UPS operation to dislodge and/or drag any foreign bodies into
the equipment, which would result in system failure and possible supply interruption to the
critical site load, and several hours of downtime resulting from the damage typically associated
with such events.
If the UPS is left running/operational after placement into service and testing, the room must
be kept clean to prevent foreign bodies from entering the UPS module via its forced air-flow.

2.3.2 Storing the UPS and Batteries for Delayed Installation
If the UPS system will not be installed immediately, store it indoors in a clean, dry, and cool location (see
Table 5.3 on page42). If the system includes a battery cabinet, the batteries’ requirements dictate the
storage conditions. Unpacked, install, and charge batteries 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 discharge during storage. Batteries must be recharged as recommended by the
battery manufacturer. A notice of “Charge Before Date” is affixed to each cabinet that has
batteries inside. The “Charge Before Date” is calculated based on storing the batteries at 77°F
(25°C). Storage at a higher temperature will increase the rate of self-discharge, which requires
earlier recharge. Consult the battery manufacturer on how to determine when the batteries
need to be recharged.
2.3.3 Installation Altitude
The maximum operating altitude of the UPS, without derating, is 3300ft(1000m).
2.4 Positioning
The cabinet is structurally designed to permit lifting from the base with a forklift, pallet jack, or similar
equipment.
Access to the power terminals, auxiliary terminal blocks and power switches is from the front and top.
The doors and top low-voltage cover can be opened for access to the power connection bars, auxiliary
terminal blocks and power isolators. The front door can be opened 90 degrees for more flexibility in
installations.
2.4.1 Moving the Cabinets
Plan the travel route between the point of arrival and the unit’s position 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, and so on, are adequate and that there are no impassable corners or changes in the
level of corridors that would prevent passage.
Ensure that the UPS weight is within the designated surface weight loading (kg/cm2) of any handling
equipment. For weight details, see Table 5.2 on page41.
Move the UPS with a forklift or similar equipment to ease the relocation and to reduce unit vibration. The
bottom structure of the UPS will support the unit only if the forks are completely beneath the unit. The
optional battery cabinets also should be moved with a forklift or similar equipment.
Ensure that any equipment used in moving the UPS cabinet has sufficient lifting capacity to transport
the unit. Care must be taken to protect the panels. Do not tilt the UPS or other system cabinet more than
15degrees.
Handling with straps is not authorized.
2 Mechanical Installation 5

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. 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. The UPS module weighs up to 4667 lb. (2117 kg).
2.4.2 Clearances
The UPS has no ventilation grilles at either side or at the rear. Leave a distance of 24in. (610mm) between
the top of the UPS and any overhead obstacles for service and adequate circulation of air from the unit.
Clearance around the front of the equipment should be sufficient to enable free passage of personnel
with the doors fully opened, about 50in. (127cm). In the rare instance of module replacement, 50in.
(127cm) of clearance is required for the Service team to perform module replacement. 50in. (127cm)
allows adequate clearance for both the module and the heavy-duty lift used by Service team to remove
and replace the modules. If 50in. (127cm) is not available, then the Service team will instead replace
components and subassemblies in the modules as part of their repair process.
2.4.3 Raised-Floor Installations
If the equipment will be installed on a raised floor, mount the UPS on a pedestal suitably designed to
accept the equipment-point loading. Refer to the base view to design this pedestal.
2.4.4 Floor Anchors—Optional
For seismic-resistant installations, special floor anchors must be used for the UPS and matching battery
cabinets; see 5on page39.
2.4.5 Kick Plate Installation—Standard
Kick plates must be installed. If the unit will be installed in a position that does not permit access to rear of
the UPS, install the kick plates before the unit is placed in its final position.
2.4.6 Special Considerations for 1+N Parallel Systems
Consider the grounding configuration of your system before finalizing module placement See Configuring
Ground Connections on page 29.
The cabling impedance must be closely matched to ensure proper load-sharing. Mismatched impedance
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. We recommend matching the impedance in the
bypass path of paralleled systems as closely as possible to ensure good bypass current sharing.
The 1+N UPS Bypass Current Sharing Inductor option can be used to minimize the effects of cable
impedance mismatch.
The impedance mismatch can also 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 impedance are closely matched.
