 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) Push the Opening button by a small and flat screw driver to open the desired pin hole.
(3) Insert each pin terminal into its each hole. Release the Opening button to clamp the pin
place.
(4) After inserting all three pins, insert the Power Plug into the Power Connector at PL. Fix
the plug with two(2) minus screws.
• When supplying power to the PL 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 cord 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 PL 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.
• Confirm that all wires are connected correctly.
• The torque required to tighten these screws is 0.5N•m to 0.6N•m.
• To prevent the possibility of a terminal short, use a pin terminal that has
an insulating sleeve.
• The temperature rating of field installed conductors: 75
°C or less.
2 Power Supply Cautions
• Use constant voltage and insulating transformers with capacities
exceeding 200VA.
