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 V
A per Rack. Power consumption varies
with
the system configuration (refer to
3-4-6 Current Consumption
). When pow

is applied, a surge current five 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.
