Installation and Wiring
Connect the FP power cable as follows:
!
Check to make sure the FP's power cord is disconnected.
#
Remove the plastic terminal cover.
"
Remove the screws from the 3 middle terminals, align the power wire
connectors and re-insert the screws. (Check each wire to make sure it is
securely connected)
Use no more than 0.5~0.6N•m of torque to tighten the screws.
3-2-2 Precautions: 100V FP-570-TC11 Power Supply
Please pay special attention to the following points when connecting the power
cable to the Power Terminal Block at the back of the 100V FP-570-TC11 unit.
•
For between the line and ground,
select a power supply that is low
in noise. If there is an excess
amount of noise, connect a noise
reducing transformer.
Use Voltage and Noise Reduc-
ing transformers that have ca-
pacities that exceed 100VA.
•
When supplying power to the FP
unit, please separate the input/out-
put and operation unit lines as
shown in the figure.

•
If the supplied voltage exceeds the
FP unit's range, connect a voltage
transformer.
Chapter 2, "Specifica-
tions", for the allowable voltage
range.
•
To increase the noise quality, sim-
ply twist the power cable before
connecting it to the FP unit.
•
The power supply cable must not
be bundled or kept close to main
circuit lines (high voltage, high cur-
rent), or input/output signal lines.
•
Connect a surge absorber, as shown
in the diagram, to deal with power
surges.
•
To avoid excess noise, make the
power cable as short as possible.
