Rear Door Ventilation

After the primary and secondary wiring has been installed
within the cable compartments of the switchgear assembly
and prior to energization of the equipment, the shipping wire,
on each rear door ventilation, must be removed (Figure 4.25).
Each rear door has a ventilation opening near the top and
bottom of the door and each ventilation opening flap must
free moving for proper ventilation of the equipment during
normal operation.
Each ventilation flap can be freed by cutting the retaining
wire holding the system in the closed position. The notice
placard and shipping wire can be discarded after removal.
NOTICE: Ensure the vent covers are operating freely prior
to the energizing the equipment. Failure to do so will
prohibit proper ventilation of the equipment during normal
operation.
WARNING: The rear compartment door must be closed
and bolted to maintain the integrity of the arc resistant
enclosure. The rear compartment door should not be
opened when the when the equipment is energized.
