12 Eaton 93PM Emergency Lighting UPS (50 kW, 480V Three and Four-Wire UL 924) Installation and Operation Manual P-164000569—Rev 03
CAUTION
If battery systems are located in the same room as the UPS, the battery manufacturer's environmental
requirements should be followed if they are more stringent than the UPS requirements. Operating
temperatures above the recommended range will result in decreased battery life and performance, and may
reduce or void the battery warranty.
The UPS ventilation requirements are shown in Table 2.
To allow for future power upgrades, Eaton recommends using air conditioning or ventilation sized for the fully
rated UPS kW frame size installed instead of the derated kW ordered. Sizing the site cooling infrastructure to
be capable of cooling the maximum kW frame size will allow a full power rating upgrade without having to
modify the infrastructure.
NOTE The battery system’s capacity must also be considered when planning for future power
upgrades. The battery system must either be sized to the anticipated future rating or
upgraded with the power upgrade. See Table 1 for battery cabinet requirements.

The UPS cabinet uses forced air cooling to regulate internal component temperature. Air inlets are in the front
of the cabinet and outlets are on top or in the back of the cabinet. Allow clearance in front of and on top or in
back of the cabinet for proper air circulation. The clearances required around the UPS cabinet are shown in
Table 4.
