Power Supply Units
Section 3-4
Caution Abide by the following precautions when wiring the Power Supply Units. Failure
!
to abide by these precautions my cause faulty operation or damage to the Unit.
• Be sure that no wire clippings or other foreign materials enter the Units when
wiring.
• Provide circuit breakers and other protective devices to protect the system
again external short circuits.
• Check and recheck all wiring before supplying power to the system.
• After wiring the terminals check the terminal block to be sure it is firmly locked
in place.
Power Requirements
A
CV-series PC consumes up to 200 VA per Rack. Power consumption varies
with the system configuration (refer to 3-4-6 Current Consumption). When pow
-
er is applied, a surge current five times the steady-state current will flow to the
PC.

Power Requirements
A
CV-series PC can consume up to 100 W of power per Rack. Power consump

tion varies depending on the system configuration (refer to 3-4-6 Current Con
sumption). When power is applied, a surge current several times the
steady-state current will flow to the PC.
Internal Fuse
Do not turn on power to the DV Power Supply Unit while the 5-V output terminals
are closed. If power is supplied when the 5-V output terminals are closed, the
internal fuse may blow.
