
1 Insert the AC connection plug into the device connector on the device.
 NOTE: The AC connection is secure when an audible click is heard.
2 Lay the cables correctly and in accordance with the following rules:
– Lay the cables around the device with a minimum clearance of 20 cm.
– Never lay cables over semiconductors (heat sinks)
- Excessive bending force may negatively impact the protection rating.
Lay the cables with a bending radius of at least four times the cable

Configuring the DC connection

DANGER
Risk of fatal injury due to electric shock!
Coming into contact with live connections can cause serious injury or death. When there is sunlight
present on the PV generator, there is DC voltage on the open ends of the DC cables.
› Make sure PV modules have good insulation against ground.
› On the coldest day based on statistical records, the Max. open-circuit voltage of the PV modules
must not exceed the Max. input voltage of the inverter.
› Check the polarity of DC cables.
› Ensure there is no DC voltage present.
› Do not disconnect DC connectors under load.
