Voltage supply
Internal 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 inputs E1/E2.

Note!
In the case of an external voltage supply and for greater distances between the
control cabinets, always use a separate power supply unit (SELV/PELV) that is
safely separated in accordance with EN 61800−5−1 in each control cabinet.
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.
