6. Connection of communications

This chapter explains the process for wiring the connections through the combiner box.
Optionally, a communication system can be installed in the inverter in order to establish a connection with the unit
to monitor and configure it, either locally or remotely, depending on the type of communication chosen and the
needs of the installation.
The INGECON SUN 3Play TL U M have local serial communication via RS-485. In addition there is the option
of establishing connections using other technology types. Connection via RS-485 is specified in this section, in
addition to routing the modem antenna cable in the event it is installed.
See the corresponding communication accessories manual and the inverter installation and operation
manual for further information.
Read carefully before starting the connection process.

6.1. Safety instructions for connecting communications

Consult section "Important Safety Instructions" and the following instructions before working on the
unit.
Make sure there is no voltage present on the unit before starting the connection. Do not switch on the
power to the unit until you have successfully made the rest of the connections and the unit is closed.
Ingeteam accepts no liability for any damages caused by incorrect connection.
