Connection Of Accessories For Communicating With The Wattmeter In The Instantaneous Self-Consumption; Connecting The Potential-Free Auxiliary Relay - Ingeteam INGECON SUN 10TL Manual De Instalacion Y Uso

Connection of accessories
7.5. 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.
INFO
For more information on installing this element, see the instantaneous self-consumption manual.

7.6. 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 0.25 and 2.5 mm
least two poles.
To insert the cable into the unit, use one of the precut holes protected with a cap. Remove the cap and fit the
corresponding packing gland.
To ensure the unit's level of protection, follow the permitted diameter range indicated in section "2.9. Description
of cable inlets".
Once the packing glands have been fitted, insert the cable and connect it to the corresponding terminal. Use the
terminals marked OD1A and OD1B. As it is a potential-free relay, there is no polarity.
