DANGER!
Danger to life as a result of high voltages in the inverter!
Before opening the inverter, please pay attention to the following points:
- Switch off the miniature circuit-breaker and ensure that it cannot be unintentionally or accidentally reconnected.
- If there is a multi-function relay connected, switch off the supply voltage to the multi-function relay and ensure it cannot be unintentionally or accidentally reconnected.
- Disconnect the Electronic Solar Switch (ESS).
- Using a current clamp, ensure that no current is present at any of the DC lines. If current is present, please check the installation.
- Unlock all connected DC connectors using a screwdriver. For this purpose, use a screwdriver with a blade width of 3.5 mm.
- Insert a screwdriver in one of the side slots and remove all connectors one after the other.
There are residual voltages in the inverter. Wait at least 5 minutes until all LEDs, the display and, if applicable, the fault indicator have gone out.
Ensure that there is no voltage to the DC plugs on the inverter. If there is measurable voltage, check the installation.
Unlock the AC connector with a screwdriver and pull it off.
After this last step, your inverter is now dead.
