APPENDIX A:
ITE-HK AIR CIRCUIT BREAKER
A.1 INSERTION PROCEDURE USING THE RPR-2
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.). This is the Test position
for HK breakers.
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 racking the HK air breaker, the racking shaft
interlock must be held aside. Do this by holding the interlock
paddle aside while pressing and holding the RPR-2 Jog button
for the duration of one cycle. (Figure A.1) this will turn the
breakers racking shaft far enough to hold the interlock paddle
aside.
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:

If ao any oimt during oht instroiNn prNctss oht Instro buooNn is
rtltastd, oht oNwtr lighos and ptndano ligho will nNo bt illuminaotd.
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.
m
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.
