Note!
Internal voltage supply of the fieldbus module connected to a 8200 vector
Controllers with an extended AIF interface (front of the 8200 vector) can be internally supplied. The
part of the drawing highlighted with grey shows the jumper position.
In Lenze setting, the fieldbus module is not internally supplied.
For internal voltage supply, put the jumper in the position indicated below.

4.4 Wiring to a host
This chapter informs you about networking the 2102 fieldbus module using the bus systems RS232
(LECOM-A), RS485 (LECOM-B) or optical fibres (LECOM-LI).
The accessories requires are listed in chapter 8.1.
Danger!
•
An additional electrical isolation is required if
– a 820X, 821X or 8200 vector controller will be connected to a host
– a safe electrical isolation (double basic insulation) to VDE 0160 is required.
•
Please observe the following:
– RS232:
The electrical isolation of the RS232 interface (LECOM-A) can be achieved by two 2101IB
level converters or another RS232 electrical isolation.
– RS485:
With RS485 (LECOM-B), the 2101IB level converter should be installed to the host if it is
not equipped with an appropriately isolated interface.
– Optical fibres:
If two controllers are connected via optical fibres (LECOM-LI) they are always isolated.
•
For wiring, the electrical isolation of the supply voltage must be taken into account.
The controllers 822X and 93XX are equipped with a double basic insulation to VDE 0160, additional
electrical isolation is therefore not necessary.
