INFORMATION
Only use safety relays with a 24 VDC supply voltage. Safety relays with uni-
versal power supply or in AC device versions have internal potential isola-
tion and are not suitable as evaluation devices.
CAUTION!
Do not connect the signal output to 0 V!
If the signal output Y32 is connected to 0 V, the safety switch may be dam-
aged as a result. Connect the signal output Y32 to a consumer, e.g. to the
input on a control system, or leave the signal output unconnected.
}
The supply voltage to the safety switch must be protected with a 2 A to 4 A quick-acting
fuse.
}
Ensure the EMC requirements of IEC 60204-1 are met.
}
When connecting in series, make sure you comply with the wiring technology require-
ments (DIN EN 60204-1) and manipulation protection requirements (EN ISO 14119).
