1. Wire the Power Supply Units so that they can be replaced safely and with-
out interrupt the power supply to other Racks or devices in the event that
a Power Supply Unit fails.
2. Branching wiring at a Power Supply Unit terminal block will create a dan-
gerous situation if a Unit must be replaced. Use relay terminals to branch
wiring and provide a circuit protector (CP) for each Power Supply Unit.
