Installation manual

5.5. Equipment configuration

Once the unit has been mounted in its final position and has been solidly secured, ensure that the inverter is properly
set up.
The units always come with factory settings, but when one of the inverters of the units is replaced or repositioned,
the inverter in question must be set up.
Care must be taken to ensure the equipment is not live when accessing its interior.

Note that in case of inverter change, the inverters come with default factory settings.
Once the unit is properly wired and before connecting it to the network and the PV array:
1. Press the emergency stop button.
2. Disconnect optical fibre cable from the inverter to be replaced.
3. Open Q4 circuit breaker on the power module controlling the inverter.

cables. Alarm 1000 will remain.
