Make sure the + / - wires are connected to the plugs

correctly (male/female) and correctly coded. The ne-
gative connection terminal on the inverter is always
closest to the wall.
If there is an adequate supply of sunlight, the inver-

ters will switch to the 'Stand-by' mode: this is indica-
ted when the LED flashes.
As the mains supply has not yet been connected, the

inverter will not generate an output voltage.
WARNING!
Risk of death by electrocution!
The unit may only be connected to the grid by qualified

personnel in accordance with the regulations of the local
power supply company.
