3.3.1 Preparing the Connection
Take off the case lid of the inverter's lower part. To this end remove the two hexagon
socket screws (M5) accessible from the front.
Inside the lid there is a tab and receptacle connector with a green-
yellow grounding cable (PE). Carefully disconnect this connector. Af-
ter finishing the installation reconnect it.
Make sure the two automatic circuit breakers F1 and F2 are switched off.
After removing the two fastening screws the lower part of the plastic clamp cover can
be removed as well ("lower protective cover").
Always mount this "lower protective cover" again before connecting
any power supply units.
You now have the open part of the inverter in front of you and can familiarize yourself
with the position of relevant components and clamps.
