11. Push the fuse holders back into position.
12. Repeat steps 7 to 11 for all string inputs in use.
13. Reconnect all DC cables to the corresponding inputs on the inverter.
14. Replace the front and bottom covers. See section Removing and replacing the
front cover and bottom cover on page 51 .
15. Perform the following applicable actions:
- Switch on all disconnecting switches and circuit breakers on the DC side.
- Switch ON the DC switch of the inverter.
16. Check that the inverter resumes normal operation.
17. Monitor the inverter for a few days to ensure that it is working correctly.
Replacing the surge protection device
The surge protection device has 3 cartridges which are consumable parts. When a
DC side voltage surge occurs, for example because of a thunderstorm in the area,
the SPD cartridge might wear out. The indicator on a worn out cartridge will turn from
green to red and the inverter shall give warning code 1001. A cartridge with a red
condition indicator must be replaced to ensure that surge protection is functioning
correctly. For the correct SPD cartridge type see
DC Input data and solar array
requirements on page 113 .
1. Turn the inverter’s DC switch to ‘0’.
2. Remove the front cover. See section Removing and replacing the front cover and
bottom cover on page 51 .
3. Check the condition of cartridges. See Layout drawing on page 25 . Is the indicator
green or red?
4. Replace cartridges which have a red indicator with new ones of the same type.
5. Replace the front cover. See section Removing and replacing the front cover and
bottom cover on page 51 .
6. Turn inverter’s DC switch to ‘1’.
7. Reset the active ‘Replace SPD’ warning. See section Generic actions to perform
if there is an active fault message on page 101 .
8. Check that the inverter resumes normal operation.
9. Monitor the inverter for a few days to ensure that it is working correctly.
