NOTE! Connecting the DC wiring
with the wrong polarity may cause
damage to the inverter. Check
both the polarity and the open cir-
cuit voltage.
WARNING! An electric shock can be fatal. Danger due to DC voltage from solar
modules.
Once a solar module string is connected, the lower clip of the respective fuse
holder is energized (even with the DC main switch in the off position).
Before commissioning the inverter insert metal slulgs or correctly sized fuses with
fuse covers into the respective fuse holder.
CAUTION! Danger of damaging the inverter by overload.
- Only connect a maximum of 20 A to an individual DC terminal.
- Connect the DC+ and DC- cables to the correct DC+ and DC- terminals on-
the inverter.
