Wiring
The wiring is defined in the circuit diagram of the PNOZmulti Configurator.
Please note:
}
Information given in the
Technical details [

must be followed.
}
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
connected on the PNOZ m EF 2MM but should be connected directly to the GNDs on
the connected units. otherwise noise susceptibility may be increased significantly (con-
ductor loops are not permitted).
CAUTION!
Only connect and disconnect the expansion module when the supply
voltage is switched off.
