Description of the device

3.1

Mode of operation

The device converts the DC voltage generated by the PV-modules into AC voltage and feeds this into the power grid. The
starting procedure begins when there is sufficient sunlight and a specific minimum voltage is present in the device. The
feed-in process begins once the PV generator has passed the insulation test and the grid parameters are within the re-
quirements imposed by the grid operator for a specific monitoring time. If, as it gets dark, the voltage drops below the
minimum voltage value, feed-in mode ends and the device switches off.

3.2.1 Mechanische Komponenten
DC isolator switch (not present in S version)
The DC isolator switch is located on the housing door. of the device. The DC isolator switch is used to disconnect the in-
verter from the PV generator in order to carry out service.
Disconnecting the device from the PV generator
F Switch the DC isolator switches from 1 (ON) to 0 (OFF).
Connecting the device to the PV generator
F Switch the DC isolator switches from 0 (OFF) to 1 (ON).
3.2.2 Electrical functions
A potential-free relay contact is integrated into the device. Use this contact for one of the following functions:
Potential-free relay
The potential-free relay contact closes as soon as there is a fault during operation. You use this function, for example, to
signal a fault visually or acoustically.
