9) Select the correct racking adaptor for the breaker being
inserted. (Figure 3.1) If applicable, 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) 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) 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.)
13) 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:
N
If at any time during the insertion process the Insert button is released,
the tower lights and pendant light will not be illuminated.
14) 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.
15) 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.
