Voltage supply
External supply of the fieldbus module
Stop!
The Specifications for the communication profile DeviceNet describe the voltage supply in detail.
These values must be observed!
The corresponding Specifications can be obtained from, for instance, Allen-Bradley.
These Operating Instructions do not inform about technical data.
Note!
Internal voltage supply of the fieldbus module connected to a 8200 vector
(only applies to controllers as of nameplate data 82EV 1x 1x)
Controllers with an extended AIF interface (front of the 8200 vector) can be internally supplied. The
part of the drawing highlighted in grey shows the jumper position.
With Lenze setting, the fieldbus module is not internally supplied.
For internal voltage supply, put the jumper in the position indicated below.

Wiring to a host
Warning!
An additional electrical isolation is required if
•
a 820X or 821X controller is connected to a host and
•
a safe electrical isolation (double basic insulation) to VDE 0160 is required.
For this, you can use an interface module for the host with an additional electrical isolation (see the
corresponding manufacturer’s information).
For wiring, the electrical isolation of the supply voltage must be taken into account. The supply
voltage is assigned to the same potential as the data bus.
