optional lifting yoke described in Step 1
mum protection can be obtained by keeping it packed as
shipped. Before placing it in storage, checks should be
made to make sure that the circuit breaker is free from
shipping damage and is in satisfactory operating
condition.
The circuit 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
3-8).
Charge the closing springs by pumping the handle up
and down approximately 38 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 circuit breaker
will close as shown by the circuit breaker contacts
“closed” (red) indicator. Push the “manual trip” button.
The circuit breaker will trip as shown by the circuit
breaker contacts “open” (green) indicator. After
completing this initial check, leave the closing springs
“discharged” and circuit 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, dirt, falling objects and excessive moisture 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 air circulation to prevent condensation. If the
building is not heated, the same general rule for heat as
for outdoor storage should be applied.
3-5 TOOLS AND ACCESSORIES
Several tools and accessories, both standard and
optional are available for use with the circuit breaker.
Maintenance Tool (Standard):
Used to charge closing
springs.
Lifting Yoke (Optional):
Used to lift circuit breaker with
overhead lifting device.
