Removal

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.

  1. 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.
  2. Remove the screws (x2) and washers (x2) that secure the cover of the Wall Connector to the casing (torque 1.1 Nm).
