to a PLC to which is mounted a non-insulated Unit (CS1W-CLK12/15(-V1),
CS1W-CLK13/53, or CS1W-ETN01) connected to an external power supply.
A short-circuit will be created if the 24 V side of the external power supply is
grounded and the 0 V side of the peripheral device is grounded. When con-
necting a peripheral device to this type of PLC, either ground the 0 V side of
the external power supply or do not ground the external power supply at all.

Note 1. To prevent damage, be sure that the jumper bar on the voltage selector ter-
minals has been removed before applying 220 V AC power.
2. If a Power Supply Unit without a RUN output is being used, an output that
acts as a RUN output can be created by programming the Always ON Flag
(A1) as the execution condition for an output from an Output Unit.
• Supply 100 to 120 V AC or 200 to 240 V AC.
• The C200HW-PA204/PA204R/PA204C supplies 100 to 240 V AC (allow-
able voltage fluctuation range: 85 to 264 V AC). The C200HW-PA204/
PA204R/PA204C has a wide-range supply voltage (100 to 240 V AC), so
voltage selector terminals are not provided.
