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 0 (1000V) must be worn
at all times a high voltage cable, busbar, or fitting is handled. Refer to Tech
Note TN-15-92-003, "High Voltage Awareness Care Points" for additional safety
