WARNING
CPU Rack
Expansion CPU Rack
Expansion I/O Rack
Wire the Units so that a Power Supply Unit can be replaced safely and easily
when the power is ON, and so that power will not be interrupted to other Racks.
To prevent danger when branching the wiring to the terminal blocks of the Power
Supply Units when a Unit is replaced, use repeater terminals for branching, and
provide a circuit-breaker for every Power Supply Unit.
Use a commercially available 100 to 120-VAC or 200 to 240-VAC power source
to supply power to the AC Power Supply Unit and a 24-VDC power source for the
DC Power Supply Unit. Expansion I/O Racks and Expansion CPU Racks must
also be connected to a power source via a Power Supply Unit. If possible, use
independent power sources for the Racks, input devices, and output devices.
Supply power to the various parts of the system (power equipment, controls, PC
system, and DC I/O, etc.) via separate power supplies.
Always supply power to the CPU Rack and Expansion CPU Rack from the same
power source. If power is supplied from separate sources or if power is not
supplied to the Expansion CPU Rack, the CPU Unit may not operate.
Turn ON the power to the Expansion I/O Racks before turning ON the power to
the CPU Rack.
