5. 5 COMMISSIONING
5.1 Safety Instructions
1. Measure the frequency and voltage of grid connection and make sure they follow the
inverter’s grid connection specifications.
2. An external circuit-breaker on the AC side (or a fuse) at 1.25*AC rated current is
strongly recommended.
3. Reliability of all earth connections must be tested and valid.
4. Before commissioning, disconnect the inverter and the circuit-breaker or fuse, and
prevent accidental reconnection.
