Wiring Precautions

Double or reinforced insulation from hazardous voltage must be applied to all input and output lines.
Failure to do so may result in electric shock.
Connect the load between the output and 0V line. (PNPoutput)
Connecting between the output and +24V line is dangerous because the operation mode is reversed to
"ON when blocked".
Do not short-circuit the output line to the +24V line.
Otherwise, the output is always ON. Also, the 0V of the power supply must be grounded so that output
does not turn ON due to grounding of the output line.
Configure the system by using the optimal number of safety outputs that satisfy the requirements of the
necessary safety category.
Do not connect each line of F3SJ to a DC power supply higher than 24V+20%. Also, do not connect to
an AC power supply.
Failure to do so may result in electric shock.
