SECTION 4: RACKING PROCEDURES

REFER TO THE APPENDIX FOR ADDITIONAL BREAKER SPECIFIC
RACKING PROCEDURES.
4.1 INSERTING POWER CIRCUIT BREAKERS
1) Follow all procedures defined by company’s Personal Protective
Equipment and Safety policy. Follow all precautions and
requirements listed in the circuit breaker IB for racking the
breaker.
2) Move the RPR-2 unit in front of the switchgear cell. Open
the cell door to allow for access to the rotary type racking
mechanism of the breaker. If the cell has closed door racking
capability, insert the racking adaptor through the provided
opening with the cell door closed.
3) Verify that the power circuit breaker is open and ready to be
racked in from the correct position. The position depends
on what type of power circuit breaker is being inserted.
This position is determined by the ability to rack in the given
power circuit breaker from the position that it can be racked
completely into the Connected position without needing any
adjustments (foot pedal pressed etc.). In most cases this is the
Test position in the cell. This can be confirmed by referring to
the breaker’s Instruction Book.
6) Turn on the power to the Power Module with the Power
Switch. (Figure 3.6)
7) The choice of the perf-a-torque will be dependent on the
breaker that is being racked. The PT-50 will be used on all
medium voltage circuit breakers and the PT-30 will be used on
all the low voltage circuit breakers.
For changing the perf-a-torque:
A 1/8” allen wrench is required to loosen the setscrew. Once the
attached perf-a-torque has been removed, replace with the desired
perf-a-torque model as indicated above. Using the 1/8” allen wrench,
secure the perf-a-torque to the racking shaft.
Setscrew Tightness:
After the RPR-2 has been used to rack several breakers, check that
the perf-a-torque is tight on the racking shaft. Tighten as needed.
4) If engaged, release the Transport Latch to allow for vertical
movement of the Power Module. (Figure 3.3)
5) Turn on the Powerware UPS for the RPR-2 by pressing the
On button for approximately five seconds and allow for the
unit to initialize. (Figure 4.5) For all other menu settings and
features, please refer to the UPS instruction CD.
