* GFDI Fuse, 1 A / 600 V / 41,0007,0187 (standard)
The inverter comes with a GFDI fuse
for negatively grounded solar modules
as standard.
CAUTION when using ungrounded sol-
ar modules!
For ungrounded solar modules:
- Remove the GFDI fuse
- Adjust the grounding settings in
the BASIC menu
WARNING!
An electric shock can be fatal.
Danger of residual voltage from capacitors.
When removing the GFDI fuse following commissioning of the inverter, wait until
the capacitors have discharged. Discharge takes 3 minutes.
Fuse holder for solar module ground at the neg-
ative pole
The fuse holder for the grounding of
the solar modules is located on the re-
verse of the inverter.
The inverter may also be operated with solar modules which require grounding on
the positive pole.
IMPORTANT!
The grounding of the solar modules on the positive pole does not
work via the fuse in the inverter, and instead must be carried out via a separate
fuse outside of the inverter. The GFDI monitoring of the inverter remains in
place.
