Connecting the Power Cord
When connecting the DC type power cord, be sure to follow the procedures given below.
(1) Confirm that the power cord is unplugged from the power supply.
(2) Loosen the three screws in the center of the Power Plug.
(3) Strip the membrane of the power cord, twist the wire ends, and connect them to the
Power Plug.
(4) Fix it with screws.
•
When supplying power to the PS-G unit, please separate the input/output and operation unit lines.
•
To increase the noise resistance quality of the power cord, simply twist each power wire before
attaching the Ring Terminal.
•
The power supply cable must not be bundled or positioned close to main circuit lines (high
voltage, high current), or input/output signal lines.
•
To avoid excess noise, make the power cord as short as possible.
•
If the supplied voltage exceeds the PS-G unit’s range, connect a constant voltage transformer.
•
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.
•
Must be used with a Class 2 power supply. (DC24 V)
•
Connect a lightening surge absorber, as shown in the diagram, to deal with power surges.
• The torque required to tighten these screws is 0.5 to 0.6N
•
m.
• Do not solder the cable connection.

Power Supply Cautions
• Use constant voltage and insulating transformers with capacities
exceeding 100VA.
• Be sure to ground the surge absorber (E1) separately from the PS-G unit
(E2).
• Select a surge absorber that has a maximum circuit voltage greater than
that of the peak voltage of the power supply.
