Shorten L and N by 5 mm each. Thus, the grounding conductor will be released from the connecting terminal plate last when tensile load is applied.
Strip 15 mm of the insulation of L, N and the grounding conductor.

Connect L, N and the grounding conductor to the connecting terminal plate for the AC connection in accordance with the labeling. When doing so, ensure that the conductors are plugged completely into the terminals up to the insulation.

Useful hint: To release the conductors from the terminals, the terminals must be opened. To do this, stick a flat-blade screwdriver (blade width: 3 mm) as far as it can go into the rectangular opening behind the terminal.

Ensure that all terminals are allocated to the correct conductors. Make sure that all conductors are securely in place. 
Plug the connecting terminal plate with the connected conductors for the AC connection into the slot in the inverter until the connecting terminal plate clicks into place.

The battery connection cables must be fitted with the supplied DC connectors. Assemble the DC connectors as described in the following. Be sure to observe the correct polarity. The DC connectors are marked with the symbols "Battery (+)" and "Battery (−)" .

Strip 12 mm of the cable insulation.
Insert the stripped cable into the DC connector up to the stop. When doing so, ensure that the stripped cable and the DC connector are of the same polarity.
Press the clamping bracket down until it audibly snaps into place. 

The inverter is connected. You must now perform data communication and tracking.

Insert the RJ45 plug of the network cable into the network pin connector on the inverter until it snaps into place.
Ensure that the network connector is securely in place by pulling slightly on the network cable.
Connect the other end of the network cable to the local network (e.g. via a router). You can only connect the inverter to other nodes via star topology.
