Front door

ON/OFF switch

The On/Off switch integrated into the front door disconnects the central
inverter in question from the auxiliary power supply (AC grid). In the
process, activation of the central inverter is interrupted. The central
inverter is isolated from the AC grid and the display switches off. The
central inverter no longer participates in communication with other system
components. If you are using the manufacturer's system monitoring, the
Monitoring Display displays a corresponding message.
If the On/Off switch is switched off, the central inverter is no longer
supplying power. For technical reasons, it may be the case that the device
switches off with a time delay (0.2–2 s).
