15. Connecting the digital inputs
These units feature a DRM0 input required to comply with Australian regulation AS4777.2, and two digital inputs
that are configurable for different purposes.
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. Check that the
protections for the grid/genset, critical loads, storage system and PV array are open.
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.
