5.1.1 Housing

The HV unit housing is a stainless steel enclosure
with a removable bottom cover. This housing is
provided with legs for safe transportation and
storage. However, these legs are not intended to
be used for mounting the recloser on its structure.
The HV unit has a dedicated name plate, showing
important rating information, serial number and
manufacturing year, mounted on the front side
of the HV cabinet. The ON/OFF position indicator
is also on the front side and is visible from ground.
A 50 W heater is provided in the HV cabinet
to prevent condensation. The heater must
be energized at all times.
