! DANGER
To ensure maximum protection against hazardous contact
voltages while assembling photovoltaic installations, both
the positive and the negative leads must be strictly isolated
electrically from the ground potential (GP).
! CAUTION
Risk of damage.
Be sure that the polarity is correct when you make the connec-
tion. Connecting it wrongly will cause damage to the inverter.
The positive or negative connection of the PV genera-
tor must be grounded. To find out which way is correct,
ask the module manufacturer. If there is no preferred
grounded connection by the module manufacturer we
recommend grounding the Negative as this is the most
common method.
Connect three strings to the three PV+ clamps (Figure
5.7)
Connect three strings to the three PV- clamps (Figure
5.8)
Clamp the enclosed cable bridge in the upper GFDI ter-
minal and the DC+( Figure 5.7) or DC-connection (Figure
5.8. Consult the module manufacturer for information
on which generator pole should be earthed.
Negative Grounded System (Factory Default)
NOTE
In this configuration the Negative of the PV generator
is grounded through the GFDI fuse.
