DANGER!
Danger to life as a result of high voltages in the inverter!
Before opening the inverter, switch off the circuit breaker and ensure that it cannot be unintentionally or accidentally reconnected.
- Disconnect the Electronic Solar Switch (ESS).
- Remove all DC connectors.
- Check whether all LEDs and the display have gone out.
There are residual voltages in the inverter. Wait 15 minutes before opening the inverter.
Open 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.
Ensure that there is no voltage to the protective conductor on the AC terminal. If there is measurable voltage, check the installation.
After this last step, your inverter is now open and dead.
