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.
}
The supply voltage to the safety switch must be protected with a 2 A to 4 A quick-acting
fuse.
}
Ensure the wiring and EMC requirements of EN 60204-1 are met.
