L BA2141 EN 1.0

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.
