Connection of accessories
Once the hole has been opened, insert the packing gland. Secure it to the housing with its nut.
8.3. Wiring process
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
figure above on the electronic circuit board, and use them to insert the card of the accessory.
After connecting the card or the corresponding connectors, insert the cable necessary for its proper installation into
the unit through the packing glands shown in the previous figure.
To ensure the protection rating of the unit, the cabling used must have a diameter of between 4.5 and 10 mm.
After connecting the optional accessories, and if you are not going to modify the ground connection,
close the unit housing (see the figure in chapter "7.3. Opening the housing").
The torque for these front screws is 6 Nm.
8.4. 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 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.
