DANGER
Risk of fatal injury due to electric shock
Severe injury or death will result if the live connections are touched. When there is solar radiation, DC
voltage will be present at the open ends of the DC cables.
›
Do not touch the exposed ends of the cables.
› Avoid short circuits.
Connecting the PV generator
1. Remove protective caps from the DC connection plugs.
2. Connect PV generator to the DC plug connectors on the underside of the housing.
3. Ensure that the unused plug connectors are sealed with protective caps.
» The inverter is connected to the PV generator.
