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 an
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.
