Illustration 2.8: Parallel Configuration
The inverter runs an automatic PV configuration test just after connection to grid. During this test
the configuration of the PV modules is determined. The status of the test and the result can be
found in menu B in the display. The inverter will always run according to the configuration of the
PV modules.

Check that cores are connected properly.
Slide the cap over the bush insert until locking catch is in correct position.
Now slide seal ring into the cap, and tighten the pressure screw.
