DANGER
Risk of fatal injury due to electric shock
Severe injury or death will result if the live connections are touched. When there is sunlight present
on the PV modules, there is DC voltage on the open ends of the DC cables.
› Do not touch the exposed ends of the cables.
› Avoid short circuits.
Connecting the PV generator
. Remove protective caps from the DC connection plugs.
. Connect PV generator to the DC plug connectors on the underside of the housing.
. Meet the requirements of protection rating IP by closing the unused plug connectors with protective caps.
» The inverter is connected to the PV generator.
. Generator grounding (optional)
Some module manufacturers stipulate that the solar modules must be grounded at the generator (especially when
applied to thin- lm modules). An optional grounding kit for use on galvanically isolated Powador inverters is availa-
ble for this purpose.
NOTE
When grounding the generator poles, heed the information provided by the module manufacturer.
Installing the grounding kit
. Remove the fuse holder cover with a screwdriver
. Attach fuse holder using the available screws
. Connect black cable in the DC terminal with the label "GFDI" (below)
. Install green/yellow PE cable to the provided PCB attachment using the cable lug
. For Powador - Plug PE cable with wire sleeve into PE terminal
. Clamp accompanying cable link into upper GFDI terminal to DC+ or DC-
. Activate grounding monitoring in the parameter menu. (See Section . on page )
