Caution
The following diagrams show the proper way to connect the power supply to the
Power Supply Unit. The terminals marked “NC” are not connected internally.
Wire the Power Supply Unit only to the specified AC voltage. Wiring to the wrong
voltage can cause fires.
Do not touch any of the terminals or terminal blocks while power is being
supplied. Doing either of these may result in electric shock.
Tighten the screws on the terminal block for AC power supply to a torque of
0.8 N•m. Loose screws may result in short-circuits, malfunctions, or burning.
Abide by the following precautions when wiring the Power Supply Units. Failure
to abide by these precautions may cause malfunctions or damage to the Unit.
• Be sure that no wire clippings or other foreign materials enter the Units when
• Provide circuit breakers and other protective devices to protect the system
• Check and recheck all wiring before supplying power to the system.
A CVM1D PC consumes up to 200 VA per Rack. Power consumption varies with
the system configuration (refer to 3-6-10 Current Consumption). When power is
applied, a surge current five times the steady-state current will flow to the PC.

Isolation Transformer
• Noise between the PC and ground can be
significantly reduced by connecting an
isolation transformer. Do not ground the
secondary coil of the transformer.
