}
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.
}
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.
}
Connect the metal housing of the safety switch to the equipotential bonding system.
}
The supply voltage for the auxiliary contact must be provided via a Class III power supply.
}
Limit the current for the auxiliary contact to 7 mA.
}
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.
Pin assignment
The safety switch is shown in an unoperated condition.
