6.1 Wiring
The wiring is defined in the circuit diagram of the PNOZmulti Configurator.
Please note:
} Information given in the "Technical details" must be followed.
} Use copper wire that can withstand 75°C.
} The cable used to connect the rotary encoders and the proximity switches must be
shielded (see connection diagrams in the chapter entitled "EMC­compliant 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 ( ) should not be connected
on the PNOZ m EF 2MM but should be connected directly to the GNDs on the connec­
ted 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.
