The CPU Power Supply is mounted to the rightmost slot of the CPU Rack. Three
models of Power Supplies are available: 100 to 120 VAC, 200 to 240 VAC, and
24 VDC. Any one of the three models can be used in the C1000H or C2000H
Simplex Systems: however, the 3G2A5-PS221-E/PS211-E Power Supplies
cannot be used in the C2000H Duplex System. The table below summarizes the
output capacity of the three models and the current available for I/O Units
mounted on the CPU Rack.

Note Be sure to keep the total power consumed by all the Units mounted on a Rack
within the value stated in the table above. For example, do not mount I/O Units
with a total current consumption of 5 A to a Rack supplied by a 4 A Power Supply.
As shown in the table above, the available current for I/O Units is only 5 A. For
details concerning current consumption, refer to Section 4 System Connections
This Power Supply is used in C1000H and C2000H Simplex Systems.

Connect a 100 to 120 VAC or 200 to
240 VAC power source.
Short these terminals to select 100 to
120 VAC. Open them to select 200 to
240 VAC.
Ground this terminal at a resistance of
less than 100 W to improve noise
immunity or prevent electric shock.
Ground this terminal at a resistance
of less than 100 W to prevent electric
shock.
Use these terminals to supply power
to DC Input Units. Use a separate
Power Supply if the I/O Unit requires
more than 0.8 A. If a current higher
than 0.8 A is output, the PC stops.
These terminals are short-circuited as
a factory-set condition. Remove the
short-circuit bracket to start or stop
the PC with an external signal. Nor-
mally, leave them short-circuited.
These terminals are turned ON dur-
ing RUN operation.
