Depending on the type of accessory to install you must use the connector INGECON Connect or those marked as
INGECON Comm of the inverter power card.
If the accessory must be connected in the INGECON Connect, you must install the two vertical guides shown in the

After connecting the card or the corresponding connectors, insert the cable necessary for its proper installation into
the unit, using a coupling, through the precut hole for the communication accessories.

7.3. 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 estimated power of the PV array exceeds the load power. When this mode is
selected, the user will also have to enter another configuration parameter: the load power.
The gage of the cables used must be between 0.00039 in
connected using a conduit with at least two poles.
Insert the cable into the unit, using a coupling, through the precut hole for the communication accessories.
