1.3 Environmental Considerations
1.3.1 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
Environmental Parameters in Table 13 ).
The Liebert
®
NXL
™
UPS is cooled with the aid of internal fans. To permit air to enter and exit and
prevent overheating or malfunctioning, do not cover the ventilation openings.
The Liebert
®
NXL
™
UPS is equipped with air filters located behind the front doors. A schedule for
inspection of the air filters is required. The period between inspections will depend upon
environmental conditions.
When bottom entry is used, the conduit plate must be installed.
1.3.2 Storing the UPS and Batteries for Delayed Installation
If the Liebert
®
NXL
™
system will not be installed immediately, it must be stored indoors in a clean,
dry and cool location (see Environmental Parameters in Table 13 ). If the UPS includes batteries,
either internally or in a battery cabinet, the batteries’ requirements will dictate the storage
conditions. Batteries should be unpacked, installed and charged 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 self-discharge during storage. Batteries must be recharged as recommended by the battery
manufacturer.
A notice of “Charge Before Date” is affixed to each unit that has batteries inside. The “Charge Before
Date” is calculated based on the batteries being stored at 77°F (25°C). Storage at a higher temperature
will increase the rate of self-discharge, requiring earlier recharge. Consult the battery manufacturer on
how to determine when the batteries need to be recharged.
1.4 Positioning
The cabinet is structurally designed to handle lifting from the base.
Access to the power terminals, auxiliary terminal blocks and power switches is from the front.
The door can be opened to give access to the power connection bars, auxiliary terminal blocks
and power isolators. Front door can be opened at 180 degrees, and interior doors can be removed
for more flexibility in installations.
NOTE
To ensure proper airflow, the unit must be installed only on a solid surface made of a
noncombustible material, such as concrete.
NOTE
The UPS is suitable for mounting on concrete or other non-combustible surface only.
NOTE
The UPS must be placed a solid surface. There must be no openings in the surface except those
required for conduit landing areas. All provided kick plates must be installed.
