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 +24V line. (NPN output)
Connecting between the output and 0V line is dangerous because the operation mode is
reversed to "ON when blocked".
Do not short-circuit the output line to the 0V line.
Otherwise, the output is always ON. Also, the +24V 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.
