General wiring guidelines

The wiring is defined in the circuit diagram of the PNOZmulti Configurator.
Please note:
Information given in the
}
Use copper wire that can withstand 75° C.
}
The power supply must meet the regulations for extra low voltages with protective sep-
}
aration.
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.
6.2

Connecting the supply voltage

Connect the supply voltage to the base unit:
Terminal 24 V and A1 (+): + 24 VDC
}
Terminal 0 V and A2 (-): 0 V
}
6.3

DeviceNet interface

It is possible to define which outputs on the control system will communicate with Devi-
ceNet. The connection to DeviceNet is made via a 5-pin screw connector.

Termination DeviceNet
To minimise cable reflection and to guarantee a defined rest signal on the transmission line,
DeviceNetmust be terminated at both ends.
