}
Ensure the wiring and EMC requirements of EN 60204-1 are met.
}
Refer to the notes on wiring in EN 60079-14.
}
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.
}
Ensure that the safety switch's electrical connections cannot work loose.
}
Protect the safety switch's electrical connections from corrosion.
}
The safety contacts are not short circuit-proof.
}
UL requirement: the supply voltage must be provided via a Class 2 power supply.
WARNING!
Ignition in a potentially explosive area!
Unintentionally removing the connector while voltage is applied may trigger
an explosion, causing serious injury and death.
– Switch off the supply voltage before removing the connector.
– Protect the connector from being removed unintentionally.
