2.0 UPS INSTALLATION AND
COMMISSIONING
2.1 Unpacking and Inspection
The Liebert™ EXS™ is shipped on a pallet. The UPS is equipped with casters that permit two or
more people to roll it off the pallet for installation. The Liebert™ EXS™ should be moved as close
as practical to its installation location before its packing is removed or the shipping brackets
loosened.
Inspect the UPS for damage. If any problem is found, file a damage claim with the carrier
immediately and send a copy to Vertiv™ at:
Vertiv™
1050 Dearborn Drive
P.O. Box 29186
Columbus, Ohio 43085 USA
Attn: Traffic Department
Check the accessories and model numbers against the delivery list. If any problem is found,
notify your local Vertiv™ representative immediately.
2.2 Installation Tools
The following tools are required to properly install your UPS:
• Pallet jack / Forklift
• Utility Knife
• 19mm (3/4 in.) open wrench or adjustable wrench (Crescent Wrench)
• 16mm (5/8 in.) wrench or socket
• 14mm (9/16 in.) wrench or socket
• 13mm (1/2 in.) wrench or socket
• #1, #2, and #3 Phillips-head screwdrivers
• Torque wrench
• Torque screwdriver
2.3 Removing the UPS from the shipping pallet:
1. Use a forklift, pallet jack, or other lifting device to move the packaged Liebert™ EXS™ as
close as practical to its intended installation location.
2. Remove the protective packing; see Figure 9.

Vertiv | Liebert®EXS™, 10kVA Quick Start Guide | 5
3. Locate the included accessories from their packing location on top of the UPS and set
them aside.
4. Unbolt the shipping brackets from the pallet with a 14mm (9/16”) wrench or socket and
then unbolt the shipping brackets from the front and rear of the UPS with a 16mm (5/8”)
wrench or socket.
5. Retain the brackets to secure the installed UPS to prevent it from tipping; or to secure it
to the floor Note: this step is not required for a Liebert® EXS™ with more than two
battery strings (wider UPS).
6. Raise the leveling feet so that they will not interfere with the ramp.
7. Place the ramp onto the pallet at the front of the UPS and gently roll the UPS down the
ramp to the floor; refer to Figure 10.

2.4 Installation Preparation
2.4.1 Environmental Requirements
Installation Area
The Liebert® EXS™ is designed for indoor installation in a clean, well-ventilated environment.
Internal fans provide forced-air cooling for the UPS. Cooling air enters through the front panel
and the hot air is exhausted through the back. Per National Electric Code, at least 3 ft. (914mm)
clearance in the front and rear of the Liebert® EXS™ is required for installation and
maintenance (see Figure 11). No side clearance is required. Only 8 inches (203mm) rear
clearance is required during operation.
Figure 11 Installation clearances
Storage
If the Liebert® EXS™ is not installed immediately, it must be stored indoors and protected from
excessive
moisture, heat and other harsh conditions. The batteries must be stored in a dry, well-
ventilated environment
with a temperature range of 68°F ~ 77°F (20°C ~ 25°C).
NOTICE
Risk of failure to properly charge batteries can damage the batteries and void the
warranty.
Batteries will lose charge during storage. Batteries must be recharged as recommended
by the battery manufacturer every 3 to 6 months, depending on storage temperature.
Approximate times to charge stored batteries are:
• 68-77°F (20-25°C): after 6 months in storage
• 78-86°F (26-30°C): after 3 months in storage
• 87°F or higher (31°C or higher): after 1 month in storage.

2.5 Connecting Power Cables
When connecting input and output cables, follow national and local wiring regulations, take the
environment into account and refer to NFPA 70, Table 310-16.
It is recommended to use parity sized ground conductors. Tables 2 and 3 below list the
minimum size cables and recommended overcurrent protection device.
