• When supplying power to the GP
unit, please separate the input/
output and operation unit lines, as
shown.
• To increase the noise resistance
quality of the power cable, 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.
• Connect a lightning surge ab-
sorber, as shown in the diagram,
to deal with power surges.
• To avoid excess noise, make the
power cable as short as possible.
• Be sure to ground the surge
absorber (E1) separately from
the GP unit (E2).
• Select a surge absorber that
has a maximum circuit voltage
greater than that of the peak
voltage of the power supply.
