Wiring
The wiring is defined in the circuit diagram of the PNOZmulti Configurator.
Please note:
}
Information given in the
}
The position of the expansion module is specified in the Hardware configuration of the
PNOZmulti Configurator.
}
Use copper wiring with a temperature stability of 75 °C.
}
The power supplies for the safety system and sensors must comply with the regulations
for low voltages with safe isolation.
}
The cable used to connect the encoders and proximity switches must be shielded (see
connection diagrams in the chapter entitled "EMC-compliant wiring").
}
The shield may only be connected to earth at a single point.
}
Earth loops should be avoided.
}
If possible, the connections for the various earth potentials (GND, A2 ) should not be con-
nected on the PNOZ m EF 1MM but should be connected directly to the GNDs on the
connected units. otherwise noise susceptibility may be increased significantly (conductor
loops are not permitted).
CAUTION!
Only connect and disconnect the expansion module when the supply
voltage is switched off.
