Load voltage supply

Notice

Fuse protection of the load voltage

The electrical fuse protection of the load voltage must be selected in such a way that the maximum current flowing is limited to 3 times the nominal current (max. 1 second)!

WARNING

Load voltage supply

The device requires an additional load voltage of e.g. 48 V DC for operation.
In order to avoid equalizing currents on the protective conductor during operation, EN 60204-1:2018 provides for the possibility that the negative pole of the load voltage does not necessarily have to be connected to the protective conductor system (SELV).
For this reason, the load voltage supply should be designed as a SELV supply.

Control voltage US

The following sub-functions are supplied from control voltage US:

Peripheral voltage UP

For EtherCAT devices with load connection and digital inputs and outputs, the load connection and digital outputs are typically supplied from the peripheral voltage UP. UP must be provided separately. If UP is switched off, the fieldbus function, the function of the inputs, and the supply of the sensors are maintained.
