nput connection to PV generator (DC side)
When the photovoltaic panels are exposed to sunlight they provide continuous DC voltage to
the inverter. To avoid risks of electrical shock, all wiring operations must be carried out with
the DC disconnect switch (internal or external to the inverter) off.
STANDARD AND -FS VERSION
Once preliminary checks have been carried out and no problems found
with the photovoltaic system, and the channel configuration has been se-
lected (parallel or independent) you may connect the inputs to the inverter.
To connect the strings, you will need the quick fit connectors (Weidmüller
or Multi-Contact) located on the lower part of the mechanics.
The number of quick fit connectors varies according to the version of the
inverters.
