Warning: Only technicians who have been
trained in High Voltage Awareness are permitted to perform this procedure.
Proper personal protective equipment (PPE) and insulating HV gloves with a
minimum rating of class 00 (500V) must be worn any time a high voltage cable is
handled. Refer to Tech Note TN-15-92-003, "High Voltage Awareness Care Points"
for additional safety information.
-
Turn off the electricity to the Wall Connector at the circuit breaker.
Warning: Electricity must be turned off at the circuit breaker
before continuing this procedure. Failure to follow this requirement
might result in serious injury or death due to exposure to high
voltage.
-
Remove the screws (x2) and washers (x2) that secure the front cover of the
Wall Connector to the casing.
-
Lift the front cover and disconnect the white ribbon cable from the
interior of the Wall Connector.
Caution: When removing the front cover, do not damage the ribbon
cable. Disconnect the ribbon cable before fully releasing the front
cover.
-
Use a properly rated voltmeter or multimeter to check for AC voltage
between terminals L1 and L2.

-
Loosen the screw that secures the yellow/green grounding wire (torque 2.3
Nm). Release the yellow/green grounding wire.
-
Loosen the screws (x2) that secure the red L1 and black L2 wires (torque
17.2 Nm).
Caution: The ferrules
on the ends of the L1 and L2 wires are one-time-use only. The ferrules or the
handle and cable assembly must be replaced if they have been previously
installed.
-
While holding the green terminal block in place with a finger, loosen the
screws (x2) that secure the purple and blue wires (torque 1.1 Nm). Release
the purple and blue wires from the terminal block.
Caution: Make sure to hold the terminal block in place so it
does not bend away from the printed circuit board.
-
Release the red and black L1 and L2 wires.
-
Use a diagonal cutter to cut the pinch clamp away from the cable.
-
Remove the screws (x2) that secure the plastic clamp to the casing.
-
Pull the cable through the bottom of the Wall Connector until the wires are
free.
