}
Ensure the wiring and EMC requirements of EN 60204-1 are met.
}
Depending on which evaluation device is used, the overall cable resistance must be
checked; before commissioning it may also be necessary to check the cross circuit detec-
tion function.
}
Make sure that the safety switch cable extends from the EX area into the non-Ex area
and that the cable connection is within the non-Ex area.
}
Protect the safety switch's electrical connections from corrosion.
}
The safety contacts are not short circuit-proof.
