I M P O R TA N T: Before installing,

connecting to supply or operating

your Liebert EXS UPS, please

review the Safety and Regulatory

Statements sheet. For detailed

installation, operating, maintenance

and troubleshooting information

visit the EXS product page for the

EXS User Guide available at

www.VertivCo.com.

INSTALLATION

Inspecting the UPS

Inspect the UPS for any signs of

obvious damage. If damage is

visible, do not proceed. File a

damage claim with the carrier

immediately and send a copy to:

Vertiv Corporation

1050 Dearborn Drive

P.O. Box 29186

Columbus OH 43085

Attn. Traic Department

Choosing a location

Install the UPS in a clean, well-

ventilated environment with the

ambient temperature range of 32°F

to 104°F (0°C to 40°C).

For installation and maintenance,

3ft (914mm) clearance is required

in the front and rear of the unit. For

proper ventilation during normal

operation, leave 8in. (203mm)

clearance on the rear. No side

clearance is required for installation

or operation of the UPS.

Handling and unpacking

the unit

The UPS ships on a pallet and is

equipped with casters that permit

two or more people to roll it o the

pallet for installation. Use a forklift

or pallet jack to move the palleted

UPS as close as possible to the

installation location before

removing packing material or

loosening shipping brackets.

1. Remove the protective

packaging, shown in the

illustration at the top-right.

2. Locate the accessories

package on top of the UPS and

set aside.

3. Use a 16-mm (5/8-in.) wrench

or socket to un-bolt the

shipping brackets from the

pallet.

4. Un-bolt the shipping brackets

from the front and rear of the

UPS. Remove the front lower

panel from the UPS to remove

the front bracket.

5. Make sure the leveling feet are

raised so they do not interfere

when rolling the unit on the

casters.

6. Roll the unit down the ramp to

the installation location, see

the illustration above, and

lower the leveling feet to fix the

UPS in the install location.

POWER WIRING AND

CONDUIT

When connecting wiring, follow the

local wiring regulations, and take the

environment situation into account.

NOTE: The conduit size and wiring

method must be in accordance with

all local, regional and national codes

and regulations, including NEC

ANSI/NFPA 70.

The maximum current for operating

modes, the recommended wire

sizes, and the recommended power

cables and plugs are listed in Tables

1 to 3, above, and are based upon

86°F (30°C) ambient temperature.

Lock-out and tag before

you begin

Ensure that the feeder breakers are

open and locked, and tagged to

prevent inadvertent operation by

unauthorized personnel.
