Installation & Operation
f. Depress the push-to-trip button and
slide the racking shaft shutter covering
the racking shaft to the left (Figure 3).
This trips the circuit breaker if it is closed
and holds it open during the racking
process.
g. Open the upper door on the cubicle.
The electric racking device is designed
to hang from the bottom flange of the
upper compartment (Figure 4). Note
the hanger is equipment with slotted
holes for adjustment (Figure 1, a) in
order to fit on standard and arc resistant
equipment. The device might need
adjustment to achieve alignment.
Lower the device over the flange and
position the drive socket on the electric
racking device over the levering-in shaft
(Figure 4). Turn the red knob on the
back of the electric racking device until
the socket engages the racking shaft.
Close and latch the upper compartment
door and latch it to capture the hanger
bracket.
h. Insert the cylindrical plug into the
remote racking device outlet (Figure 6).
Lock the plug by turning it clockwise.
i. Ensure the control box power switch is
in the “OFF” position.
j. Connect the device to a 120VAC power
source.
k. Move the power switch to the “ON”
position.
l. Move the selector switch on the push
button to the “IN” position.
Note:
The housing on the push button is a
switch, and can be rotated to either
the “IN” or “OUT” positions.
m. Physically move the motor control
box to a remote area and operate the
electric racking device.
n. To begin racking the circuit breaker into
the compartment, depress the push
button on the control box (Figure 7).
Note:
If the push button is released during
operation the motor will stop.
o. When the push button is depressed, the
“IN” indicating light (Figure 2, b) will be
energized and illuminated.
p. When the circuit breaker is fully racked
IN, the remote racking device torque
limiter will begin to slip and there will
be a clear clicking sound along with a
vibration of the racking device. At this
point, release the push button. The
breaker position indicator will read
“Connect” (Figure 9).
q. Disconnect the 120VAC source and
remove the remote racking device.
r. Slide the racking shaft shutter to the
right.
