Connecting the Power Cord
(1) Confirm that the power is not supplied to
the PL unit.
(2) Push the Opening button with a small
slot 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 minus screws.
• Confirm that all wires are connected
correctly.
• The torque required to tighten these
screws is 0.5 to 0.6 N•m.
• To prevent the possibility of a terminal
short, use a pin terminal that has an
insulating sleeve.
2. Power Supply Cautions
• Input and Output signal lines must be sepa-
rated from the power control cables for
operational circuits.
• To improve the noise resistance, be sure to
twist the ends of the power cord wires
before connecting them to the Power con-
nector (Plug).
• The PL unit’s power supply cord should
not be bundled with or kept close to main
circuit lines (high voltage, high current), or
input/output signal lines.
• To reduce noise, make the power cord as
short as possible.
• If the supplied voltage exceeds the PL
unit’s range, connect a voltage transformer.
• Between the line and ground, select a
power supply that is low in noise. If there
is an excess amount of noise, connect an
insulating transformer.
• The temperature rating of field installed
conductors: 75
°C only.
• Use constant voltage and insulating
transformers with capacities exceeding
Power Consumption value.
• Connect a surge absorber to handle
power surges.
• Be sure to ground the surge absorber
(E1) separately from the PL unit (E2).
Select a surge absorber that has a maxi-
mum circuit voltage greater than that of
the peak voltage of the power supply.
3. Grounding Cautions
• Be sure to create an exclusive ground for the
Power Cord’s FG terminal. Use a grounding
resistance of 100
Ω, a wire of 2mm 2
or thicker,
or your country’s applicable standard.
• The SG (signal ground) and FG (frame
ground) terminals are connected internally
in the PL unit.
