Voltage supply
Internal DC voltage supply
The internal voltage is available at terminal X3.1/20 or X3.2/20. It supplies the controller
inhibit (CINH) and the digital inputsE1/E2.

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.
