4.3.2 Voltage supply
•
Internal voltage supply
– If possible, use all devices without external voltage supply because of EMC-relevant
reasons.
•
External voltage supply ( ^ 4-1)
– Absolutely required for 820X controllers.
– If the 2141 fieldbus module is to be able to communicate even if the basic device is switch
off.
•
If the bus system is distributed over several control cabinets, install a separate power supply
in every control cabinet to supply all devices/fieldbus modules.
Install an equipotential bonding conductor between the control cabinets.
Tip!
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 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.
