inputs have to be closed as follows:
– Insert the provided sealing plugs into the
unneeded DC plug connectors.
Do not insert the sealing plugs into the DC
inputs on the inverter.
– Insert the DC plug connectors with sealing plugs
into the corresponding DC inputs on the inverter.

• Only connect the Electronic Solar Switch when the lid is closed.
• Only operate the inverter when the lid is closed so that the DC plug connectors
cannot be disconnected easily.
