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 cover of the Wall
Connector to the casing (torque 1.1 Nm).
-
Remove the front cover of the Wall Connector; disconnect the white flex cable
from the interior.
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. Ensure that the correct power breaker has been turned off to
de-energize the Wall Connector.
-
Loosen the screw that secures the yellow and green grounding wire (torque 2.3
Nm). Remove the grounding wire.
-
Loosen the screws (x2) that secure the red and black L1 and 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 yellow wires (torque 1.1 Nm) to the block. Remove
the wires.
Note: Make sure to hold the terminal block in place so it does not
bend away from the printed circuit board.
-
Remove the red and black L1 and L2 wires.
-
Remove the screws (x2) that secure the plastic clamp to the casing (torque 3.4
Nm).
-
Use a diagonal cutter to cut the pinch clamp away from the cable.
-
Pull the cable down through the casing until the wires are free.
