8 Disconnecting the Sunny Island from Voltage Sources
1. Switch the system off (see Section4.4, page18).
2. Disconnect the circuit breakers and the load-break switches in the sub-distributions and secure against reconnection.
3. Open the load-break switch in the DC cable and secure against reconnection.
5. Loosen all screws of the enclosure lid and remove the enclosure lid.
6. Ensure that the DC terminal is disconnected from voltage sources.
7. Ensure that the terminals AC1 Loads/SunnyBoys, AC2 Gen/
Grid and ExtVtg (position A) are disconnected from voltage
sources.
8. Ensure that the terminals Relay1 and Relay2 (position A) are
disconnected from voltage sources.
9. Ground and short-circuit the AC power cables outside the Sunny Island.
10. Cover or shield any adjacent live components.
