11. REMOVAL OF INVERTER
If it is necessary to remove the inverter proceed as follows:
1. Open the AC breaker contacts to disconnect the electricity.
2. Isolate the power feed from the photovoltaic field
3. Use a suitable meter to verify the absence of AC and DC voltages.
4. Remove the AC connections immediately
5. Remove the DC connections to isolate the PV field.
6. Remove the RS485 communication module with the computer connection.
Once these steps have been completed remove the inverter.
