APPENDIX D:
WESTINGHOUSE DH AIR CIRCUIT BREAKERS
D.1 INSERTION PROCEDURE USING THE RPR-2
Refer to the installation manual provided with each DH air breaker
racking adapter kit.
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.
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.
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.
6) Turn on the power to the Power Module with the Power
Switch. (Figure 3.6)
7) Select the correct breaker program on the Power Module by
pressing and releasing the Breaker Select Button until the
desired program is displayed on the Fusion Controller. (Figure
4.1)
8) Select the INSERT direction with the Insert/Remove switch.
(Figure 4.1)
9) Select the correct racking adaptor for the breaker being
inserted. (Figure 3.1) Place the racking adaptor on the breaker’s
racking mechanism shaft. Position the RPR-2 shaft with the
racking adaptor. Turn the Insertion Shaft Lock to Unlatched
position to allow for connection the RPR-2 into the racking
adaptor on the power circuit breaker. (Figure 3.6) An extension
can be used if a longer length is needed. If necessary, the Jog
button (Figure 3.6) can be pressed to rotate the shaft for correct
alignment (amber pendant and tower light will illuminate).
Horizontal alignment can be achieved with the casters and
vertical alignment by raising or lowering the Power Module.
(Figure 4.2)
10) Once the RPR-2 is connected, properly adjust the unit toward
the cell to insure the proper amount of travel is available for
the power circuit breaker insertion process. When an adequate
amount of travel distance is achieved, the green tower light will
illuminate.
11) Engage the foot brake on the RPR-2 truck by stepping down
on the lever. (Figure 4.6) Verify that the correct power circuit
breaker program and the Insert direction are selected by
viewing the LCD screen on the Fusion Controller (Figure 4.1).

WARNING
SELECTION OF THE INCORRECT POWER CIRCUIT BREAKER PROGRAM MAY
RESULT IN THE RPR-2 UNIT SIGNALING COMPLETION OF THE INSERTION
CYCLE WITH THE POWER CIRCUIT BREAKER ONLY PARTIALLY INSERTED.
12) In order to start the racking process for the Westinghouse DH
Air breaker the installed Push Handle will need to be pushed in
to rack the breaker. The Push Handle will be in this position for
the entire racking process. (Figure D.1)
13) Take the Pendant and move a safe distance away from
front of the power circuit breaker. (The distance should be
predetermined through Arc Flash calculations.)
14) When area is clear, depress and hold the Insert button (white
with black arrow) on the pendant. (Figure 4.3) This will initiate
the insertion process on the RPR-2 unit. The amber light on the
pendant and on the tower light will illuminate while the power
circuit breaker is in the insertion process.
Note:

15) When the power circuit breaker is in the Connected position,
the red tower light will illuminate and the amber light on the
pendant will turn off. This indicates that it is now safe to
approach the power circuit breaker.

WARNING
IF AT ANY TIME DURING THE INSERTION PROCESS AN OVER-TORQUE
OCCURS THE AMBER LIGHT ON THE PENDANT AND TOWER WILL FLASH.
(THE AUTO REVERSE SELECTION IS NOTED ON THE NAMEPLATE OF THE
RPR-2 UNIT.)
• IF THE AUTO-REVERSE FUNCTION IS SELECTED IN THIS SITUATION
THE RPR-2 WILL THEN INITIALIZE THE REMOVAL PROCESS. ONCE THIS
PROCESS IS COMPLETED THE GREEN AND AMBER LIGHTS ON THE
LIGHT TOWER WILL FLASH AND THE AMBER LIGHT ON THE PENDANT
WILL TURN OFF INDICATING IT IS SAFE TO APPROACH THE POWER
CIRCUIT BREAKER.
• IF THE AUTO-REVERSE FUNCTION IS NOT SELECTED, PRESS AND HOLD
THE REMOVE BUTTON (BLACK WITH WHITE ARROW) ON THE PENDANT.
WHEN THE POWER CIRCUIT BREAKER IS COMPLETELY REMOVED, THE
AMBER LIGHT ON THE PENDANT WILL TURN OFF AND THE GREEN
AND AMBER TOWER LIGHTS WILL FLASH INDICATING IT IS SAFE TO
APPROACH THE POWER CIRCUIT BREAKER.
16) When the Red indicator light is illuminated the Push Handle
will need to be released to operate the breaker. By lifting up
the Operator Lock the Push Handle can be disengaged and
released
17) To disconnect the RPR-2 unit, push the unit toward the
switchgear cell to disengage the brakes. Lift the brake lever up
to engage the holding magnet.
18) Turn the Insertion Shaft Lock to the Latched position. Push the
unit forward until the insertion shaft latches.
