to the frame ground (F.G.). Failure to do so may cause the product
to malfunction due to noise, resulting in serious injury or death.
The wiring should be done in a metal box connected to the frame
ground (F.G.).
Take countermeasures regarding the system to ensure that
dangerous performance caused by the earth failure cannot occur.
Failure to do so could cause jeopardize the system stop, resulting
in serious bodily injury or death.
Ground the 0V side (PNP output)/24V side (NPN output) to ensure
that the output is not turned ON by accident due to an earth fault
of the control output (OSSD 1, OSSD 2).
When this product is used in a situation where it has to conform
to the Korean S-mark, make sure to ground the 0V side (PNP
output).
Make sure to insulate the ends of the unused lead wires.
Use a safety relay unit or an equivalent safety control circuit as a
