DANGER!
Danger to life as a result of electric shock!
Danger to life as a result of high voltages in the inverter!
Before you open the inverter, pay attention to the following points:
- Ensure that the AC side is dead.
- Ensure that the DC side is dead and without current.
- Switch off the miniature circuit-breaker and ensure that it cannot be unintentionally or accidentally reconnected.
- SB 1600TL/2100TL; SB 2500/3000: If an external DC switch-disconnector is available, please disconnect it.
- Pull the Electronic Solar Switch downward, slightly toward the wall.
- 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.
- Pull out the AC connector.
- Check whether all LEDs and the display have gone out.
There are residual voltages in the inverter. Wait 15 minutes before opening the inverter.
Ensure that the DC plugs on the inverter are dead. If there is measurable voltage, check the installation.
Now loosen all encasement screws and remove the lid by pulling it forward uniformly.
NOTICE!
Damage to the inverter as a result of electrostatic discharge.
Ground yourself before touching a component.
Release the protective conductor (PE) connection locking mechanism on the lid.
After this last step, your inverter is now open and dead.
