9 Disconnecting the Multicluster System from
Voltage Sources
1. Switch off all loads.
2. Stop the multicluster system at the master of the main cluster (see Sunny Island documentation).
3. Switch all Sunny Island inverters off (see Sunny Island documentation).
4. Disconnect the PV main distribution board and secure against reconnection.
5. Shut down the generator and secure against reconnection.
6. Open the Multicluster Box.
7. In the Multicluster Box open all Sunny Island circuit breakers.
9. Remove the contact hazard protection cover (see Section 7.3, page 23).
10. Ensure that no voltage is present in the Multicluster Box.
11. Ground the PV main distribution board outside the Multicluster Box, and short-circuit.
12. Ground the generator outside the Multicluster Box, and short-circuit.
13. Cover and isolate any adjacent live components.
8.
Risk of burns
Busbars and terminals in the Multicluster Box can get hot during operation.
• Do not touch busbars or terminals.
