The UPS cabinets use forced air cooling to regulate internal component temperature. Air inlets are in the front of the cabinet and outlets are in the top.You must allow clearance in front of and above each cabinet for proper air circulation.The clearances required around the UPS cabinet are shown inTable 2-2.

From top of cabinet	Minimum clearance over the UPS cabinet is 458 mm for ventilation
From front of cabinet	915 mm working space
From back of cabinet	None required
From right side of cabinet	None required, but for easier service 500 mm is recommended.
