F3SJ-B
User’s Manual
Perform an inspection for all F3SJ-B as described in "Chapter 5 Checklists".
For wiring
Connect the load between the output and 0 V line (PNP output). Connecting the load between
the output and +24 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 +24 V line. Otherwise, the output is always ON. Also,
the 0 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 of more than 24 VDC+20%. Also, do
not connect to an AC power supply. Failure to do so may result in electric shock or breakdown of
the device.
Make sure to perform wiring while the power supply is OFF.
Do not use the auxiliary output for safety applications. Human body may not be detected when
F3SJ-B fails, resulting in serious injury.
For the F3SJ-B to comply with IEC 61496-1 and UL 508, the DC power supply unit must satisfy
all of the following conditions:
• Must be within the rated power voltage (24 VDC
±
20%)
• Must have tolerance against the total rated current of devices if it is connected to multiple
devices
• Must comply with EMC directives (industrial environment)
• Double or reinforced insulation must be applied between the primary and secondary circuits
• Automatic recovery of overcurrent protection characteristics
• Output holding time must be 20 ms or longer
• Must satisfy output characteristic requirements for class 2 circuit or limited voltage current
circuit defined by UL 508. Refer to p.63 for details.
• Must comply with laws and regulations, regarding EMC and electrical equipment safety, of the
country or region where the F3SJ-B is used (Ex: In EU, the power supply must comply with the
EMC Directive and the Low Voltage Directive.)
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.
Extension of the cable must be within a specified length. If it isn't, safety function may not work
properly, resulting in danger.
