Feedback Cabinet
The feedback cabinet has the same dimensions at the 400 kVA cabinet that is shown in Illustration 4.Cabinet Position in Room
To ensure correct ventilation, do not place anything on top of the UPS cabinet. Leave 1 m (3 ft) of free space in front of the UPS in order to allow the door to be opened. The cabinet rests on four cylindrical feet that are 60 mm (2.3 inch) in diameter. The cabinet feet are positioned at the four corners of the cabinet. Six feet are used for the 500 kVA UPS.The UPS can operate correctly with the back of the unit placed against a wall, however, space may be provided to allow for maintenance purposes. The distance between the bottom panel and the floor must be less than 10 mm (0.4 inch).Note: Abnormal temperature rise may occur if 500 mm (19.7 inch) or more of free space is not maintained above the UPS.UPS Cabinet

The optimum operating temperature range is 20° C (68° F) to 25° C (77° F). An operating temperature of 35° C (95° F) is possible, however battery life will be greatly reduced. Size the ventilation system taking into account the values in the table below.
