External voltage supply



Note!

Always use a separate power supply unit in every control cabinet and safely

separate it according to EN 61800-5-1 (”SELV”/”PELV”) in the case of external

voltage supply and larger distances between the control cabinets.

External voltage supply of the communication module is required if communication via the

fieldbus is to be maintained even when the power supply of the standard device fails.



Note!

With external voltage supply of the function module, the active bus

terminating resistor is fed independently of the operation of the standard

device. In this way, the bus system remains active even when the standard

device is switched off or fails.
