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 requirements 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.

Mechancial Components
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 discon-
nect the inverter from the PV generator in order to carry out service.

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 ex-
ample, to signal a fault visually or acoustically.
