For UPS equipment installed on a raised computer room floor, two floor through-holes
should be provided beneath the enclosure. One is for cabling and the other serves as an
air inlet for the cooling air required by the UPS. See Figure 2–2 or Figure 2–3 for the
location of these holes for your UPS.
NOTES
For nonraised floor installations, the area under the draw-out air filter must be
kept clear of obstructions for filter installation and servicing.
The UPS dissipates heat and exhausts warm air through the top portion of the enclosure.
Refer to Table 2–1 for heat dissipated (Btu/Hr). Air exhaust for models rated 20 and 40
kVA is 1200 cubic feet per minute (CFM). Air exhaust for models rated 60 and 80 kVA is
1600 CFM.
