Note When 220 V AC power (200 to 240 V AC) is being supplied, be sure to
remove the jumper bar that shorts the voltage selector terminals. The Unit will
be damaged if 220 V AC is supplied with the jumper bar connected.

Not connected
(OPEN)
CORRECT
Note If 100 to 120 V AC power is supplied but the jumper bar has been removed to
select 200 to 220 V AC, the Unit will not operate because the power supply
voltage will be below the 85% minimum level.
• Do not remove the protective label from the top of the Unit until wiring has
been completed. This label prevents wire strands and other foreign matter
from entering the Unit during wiring procedures.

Voltage selector:
Closed for 110 V AC
Open for 220 V AC
Remove the short bar before applying 200 to 240 V AC.
RUN output
ON when the CPU Unit is in RUN or MONITOR mode.
OFF when the CPU Unit is in PROGRAM mode or when a fatal error has occurred.
Power
supply
Note The RUN output can be used from either the Power Supply Units on the CPU
Rack or the Expansion Racks.
To obtain an output contact equivalent to RUN output when using a Power
Supply Unit without RUN output, use an output contact from the Power Supply
Unit with a constant ON flag as the input condition.
