The LV enclosures and the MVM enclosure are equipped with fan units. The fan units suction cooling air to the HiP-
perGuard MV UPS major components with the objective of transfer the internally generated heat to the outside of
the enclosures.
The air enters the HiPerGuard 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 HiPerGuard MV UPS
is operating. Figures 3.29 and 3.30 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.
