Wiring Precautions

Apply double or enhanced insulation from hazardous voltage to all input and output lines.
Failure to do so may result in electric shock.
Connect the load between the output and +24 V line (NPN output).
Connecting the load between the output and 0 V line will result in a dangerous condition
because operation is reversed to "ON when blocked".
Do not short-circuit the output line to the 0 V line.
Otherwise, the output is always ON. Also, the +24 V 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-B to a DC power supply higher than 24 V+20%. Also,
do not connect to an AC power supply.
Failure to do so may result in electric shock or breakdown of the device.
