CAUTION
HAZARD OF CABLE MOVEMENT IN SHORT CIRCUIT CONDITIONS
In systems over 35 kAIC it is mandatory to restrain the power cables:
  • Use 10 mm nylon rope or rope with a minimum tensile strength of 1000 kg (2204.62 lbs).
Failure to follow these instructions can result in injury or equipment damage.
  1. Route the power cables through the top or bottom of the maintenance bypass cabinet.
  2. Connect the EGC (Equipment Grounding Conductor), input cables, bypass cables (in dual mains systems), load cables, and DC cables. Assemble the cable lugs to the busbars as shown.
