6.1
General wiring guidelines
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.
}
External measures must be used to connect the
terminal to the function earth (e.g.
mounting rail).
}
Always connect the mounting rail to the protective earth via an earthing terminal. This
will be used to dissipate hazardous voltages in the case of a fault.
}
The power supply must meet the regulations for extra low voltages with protective sep
aration.
6.2
Connecting the supply voltage
Connect the supply voltage to the fieldbus module:
}
Terminal
24 V
: + 24 V DC
}
Terminal
0 V
: 0 V
6.3
PROFIBUS DP interface
It is possible to define which outputs on the control system will communicate with
PROFIBUSDP. The connection to PROFIBUSDP is made via a female 9pin DSub con
nector in accordance with the guidelines of the PROFIBUS User Group (PNO).

Setting the station address
The station address of the expansion module PNOZ mmc3p is set between 0 ... 99
(decimal) via two rotary switches x1 and x10.
