Connection Of Accessories For Communicating With The Wattmeter In The Instantaneous Self-Consumption; Connecting The Potential-Free Auxiliary Relay - Ingeteam INGECON SUN 40TL U M480 Manual De Instalacion Y Uso

Connection of accessories
7.7. Connection of accessories for communicating with the
wattmeter in the instantaneous self-consumption
To communicate between the inverter and wattmeter in an instantaneous self-consumption system, you need to
install a communications card.
For more information on installing this element, see the instantaneous self-consumption manual.

7.8. 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.
To connect the volt-free relay, keep in mind the relay´s characteristics:
The section of cables used must be between 24 AWG and 14 AWG. This device is connected using a conduit with
at least two poles.
To ensure the unit's level of protection, follow the permitted diameter range indicated in section "2.10. Description
of cable inlets".
After making the wiring connections, it will leave the unit via a coupling installed in the precut hole for the
accessories.
