Once the lifting yoke is securely seated in the lifting
holes, the breaker can be carefully lifted and moved.
Keep in mind, however, the faceplate on all 7.5 or 15 kV.
DHP-VR breakers must be removed to use a lifting yoke.
3-3 STORAGE
If the circuit breaker is to be placed in storage, maxi-
mum protection can be obtained by keeping it in the
original wooden crate. Before placing it in storage,
checks should be made to make sure that the breaker is
free from shipping damage and is in satisfactory
operating condition.
The breaker is shipped with its contacts open and
closing springs discharged. The indicators on the front
panel should confirm this. Insert the maintenance tool in
the manual charge socket opening (Figure
3-2
or
3-4
).
Charge the closing springs by pumping the handle up
and down about 36 times until a crisp metallic
“
click
”
is
heard. This indicates that the closing springs are
charged and is shown by the closing spring
“
charged
”
(yellow) indicator. Remove the maintenance tool. Push
the
“
manual close
”
button. The breaker will close as
shown by the breaker contacts
“
closed
”
(red) indicator.
Push the “manual trip” button. The breaker will trip as
shown by the breaker contacts
“
open
”
(green) indicator.
After completing this initial check, leave the closing
springs
“
discharged
”
and breaker contacts
“
open
”
.
Outdoor storage is
NOT
recommended. If unavoidable,
the outdoor location must be well drained and a
temporary shelter from sun, rain, snow, corrosive fumes,
dust, dirt falling objects, excessive moisture, etc. must be
provided. Containers should be arranged to permit free
circulation of air on all sides and temporary heaters
should be used to minimize condensation. Moisture can
cause rusting of metal parts and deterioration of high
voltage insulation. A heat level of approximately 400
watts for each 100 cubic feet of volume is recommended
with the heaters distributed uniformly throughout the
structure near the floor.
Indoor storage should be in a building with sufficient
heat and circulation to prevent condensation. If the
building is not heated, the same general rule for heat as
for outdoor storage should be applied.
