5.3.6 Mains connection
The inverter’s metal parts (unit ground) are electrically connected to the ground pin in the grid connection quick
connector.
To ensure the safety of personnel, this terminal must be connected to the installation’s ground.
Connection of network neutral, three phases and ground to the inverter is via a bayonet connector with five terminals.
The AC bayonet connector is suitable for cables from 13 to 20 mm diameter.
The following sequences must be followed during installation:
1. Cut and strip the cables as shown in the figure.
Note
For cables from 16 to 20 mm, cut the inside of the internal ring in the sealing gasket.
2. Install as shown in the figure.
3. Connect the cable ends to the connector terminals according to the pins shown in the figure. Tightening torque:
0.7 Nm.

PRECAUTION
Observe the pin assignations on the AC bayonet connector. Applying the wrong pins
could lead to the destruction of the equipment. The diagram shows the connections
inside the AC connector.
4. Screw the housing to the connector by pushing the outside ring on the connector towards the housing. Tighten-
ing torque: 1-2 Nm.
5. Tighten the screw. Tightening torque for cables from 13 to 20 mm: 6-8 Nm.
If the inverter and the grid connection point are far enough apart to require the use of cables of a greater section,
