6.3 EMC requirements and electrical safety
} Ensure the wiring and EMC requirements of EN 60204-1 are met.
} UL requirement: The supply voltage to the safety switch must be protected with a quick-
acting fuse (see Technical details [
63]).
} The power supply and the components connected to the PSEN mlm must meet the regu-
lations for extra low voltages with protective electrical separation (SELV, PELV).
} The power supply must have an overvoltage protection of ≤ 35 VDC.
INFORMATION
Only use safety relays with a 24 VDC supply voltage. Safety relays with a
wide-range power supply or in AC device versions have internal potential
isolation and are not suitable as evaluation devices.
