Connecting the digital inputs

15. Connecting the digital inputs
The management of the digital inputs varies depending on the inverter hardware type.
This chapter explains the requirements and process for connecting the digital input wiring to the unit. Read
carefully before starting the connection process.

15.1. Safety instructions for connecting the digital input

CAUTION
Before you start to make the connections, make sure there is no voltage in the inverter. Verify that the AC
protection of the auxiliary grid/genset and the DC protection of the storage system are open, as well as the PV
array and the consumption grid.
Do not switch on the power to the unit until you have successfully made the rest of the connections and the unit is
closed.
When carrying out the connections, respect the polarities marked on the electronic card.
