Because of the danger of electric shocks, be sure the power cable is
not connected when wiring the unit.

When changing the backlight, there is a danger of electric shocks
or burns, so be sure to turn the unit OFF and wear gloves.

This section assumes that the FP is the cause of a problem, not the
host (PLC). When the host is the problem, please refer to its
corresponding manual.
