8 Disconnecting the Sunny String-Monitor
1. If there is a DC circuit breaker on the Sunny String-Monitor, disconnect it. This ensures that there
is no current flowing through the Sunny-String-Monitor.
2. If there is no DC circuit breaker, disconnect the Sunny Central (see the installation guide for the
Sunny Central).
3. If there are fuses in the Sunny Central, remove them. Use an LV/HRC fuse handle to do this.
4. If there are no fuses in the Sunny Central, remove the fuses in the DC main distributor.
6. Disconnect all the DC plug connectors.
