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.
