6.1 Wiring
6.1.1 General wiring guidelines
The wiring is defined in the circuit diagram of the PNOZmulti Configurator.
Note:
} Information given in the "Technical details" must be followed.
} 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.
6.1.2 Connecting the supply voltage
Connect the supply voltage to the fieldbus module:
} Terminal 24 V: + 24 V DC
} Terminal 0 V: 0 V
6.1.3 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).
