Wiring Power Supply Units
Note
The RUN output function is provided only for the CJ1W-PA205R Power Sup-
ply Unit. It is not provided on the CJ1W-PA202 Power Supply Unit.
AC Power Source
• Supply 100 to 240 V AC.
• Keep the voltage fluctuations within the specified range.
• If one power supply phase of the equipment is grounded, connect the
grounded phase side to the L2/N terminal.
Isolation Transformer
The FQM1's internal noise isolation circuits are sufficient to control typical
noise in power supply lines, but noise between the FQM1 and ground can be
significantly reduced by connecting a 1-to-1 isolation transformer. Do not
ground the secondary coil of the transformer.
Power Supply Capacity
The power consumption will be 100 VA max. for the CJ1W-PA205R and 50 VA
for the CJ1W-PA202, but there will be a surge current of at least 5 times the
max. current when the power is turned ON.
