To ensure the unit's level of protection, follow the permitted diameter range indicated in section "2.10. Description
of wiring inlets".
7.4. Connecting the potential-free auxiliary relay
These inverters have a potential-free output which can have several functions:
•
Closing the relay in the event of an insulation fault (default option).
•
Closing the relay in the event of a grid, voltage or frequency out of range alarm.
•
Closing the relay in the event of any alarm in the inverter.
•
Closing the relay upon connection of the inverter to the grid.
•
Closing the relay if the power sent to the grid by the inverter exceeds the power setpoint parameter. The
relay can act so that a specific charge is sent to the grid.
To connect the volt-free relay, keep in mind the relay's characteristics:
This device is connected using a conduit with at least two poles.
After making the connections in the connector indicated in the previous figure, the necessary wiring for its proper
installation will leave the unit through the cable gland installed in the dedicated wiring access.
To ensure the unit's level of protection, follow the permitted diameter range indicated in section "2.10. Description
of wiring inlets".
