support lock pin (Figure 10, b) , raise the
racking device slide assembly
(Figure 12, a) . Position the racking
device close to the cell door, and lower
the slide assembly to engage the
racking device support hanger.
To avoid damage to equipment, and ensure
proper racking operation, the circuit breaker
racking mechanism must be engaged by the
racking socket before the remote racking
device is operated.

11. With the racking device installed on the
compartment door, turn the adjustment
knob until it engages the drive socket
with the circuit breaker racking shaft
(Figure 13, a) .
12. Physically move the motor control box
to a distant area to operate the remote
racking device.
The remote racking device is positioned
on the switchgear compartment door
(Figure 13) for racking out the circuit
breaker.
Note: For racking out procedures, see
Ch 5 Operation, B. Installing and

1. Plug the motor control box power cord
into a 110VAC 15A receptacle.
2. On the motor control box, move the
power switch to the
ON
position
(Figure 14, d) .
3. On the motor control box, turn the
racking direction selector to OUT
position (Figure 14, c) .
4. Depress the black push button on the
racking direction selector and the green
OUT
indicator lamp comes on
(Figure 14, b) . The remote racking device
proceeds to rack out the circuit breaker
and will vibrate slightly.
5. When racking out of the circuit breaker
is complete, the remote racking device
motor will clutch out. As clutch out
occurs, there will be a loud popping
noise, and the racking device will
vibrate strongly. At this point, release
the black push button.
