Wiring
6.1.1
General wiring guidelines
The wiring is defined in the circuit diagram of the PNOZmulti Configurator.
Please note:
}
}
Use copper wire that can withstand 75° C.
}
External measures must be used to connect the terminal
to the functional earth,
when the mounting rail is
not
connected to the functional earth.
}
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:
}
24 V
terminal: + 24 VDC
}
0 V
terminal: 0 V
}
Protect the supply voltage as follows:
–
Circuit breaker, characteristic C - 6 A
or
–
Blow-out fuse, slow, 6A
