Table 3-2. Ups Cabinet Clearances; Table 3-3. 93E Required Clearance - Eaton 93E UPS Installation And Operation Manual

The UPS cabinet uses forced air cooling to regulate internal component temperature. Air inlets are in the front
of the cabinet and outlets are in the back of the cabinet. Allow clearance in front of and in back of the cabinet
for proper air circulation. The clearances required around the UPS cabinet are shown in Table 3-2.
