Cooling system

The LV enclosures and the MVM enclosure are equipped with fan units. The fan units' intake cooling air
to the HiPerGuard MV UPS major components with the objective of transfer the internally generated
heat to the outside of the enclosures.
The air enters the MV UPS enclosures through the louver panels at the front and exits through the air
outlet at the top (except for the APS enclosure where the outlet is located on the front door).
The air intakes, including the louvers and filters, must be maintained unobstructed when the MV UPS is
operating. Figures 3.26 and 3.27 illustrate the air intake (blue arrows) and air out (red arrows).
Please refer to the Installation Manual for more information about the minimum recommended
clearances for operation and maintenance purposes.
