Note!
- Ensure that the grid neutral conductor is grounded. This may not be the case for IT
grids (insulated grids with no grounding); it will then not be possible to use the inverter.
- In order to use the inverter, the neutral conductor must be connected. A neutral con-
ductor that is too small may adversely affect the inverter feeding energy into the grid.
The neutral conductor must therefore be the same size as the other live conductors.
IMPORTANT! The PE ground conductor of the AC cable must be laid in such a way that it
is the last to be disconnected in the event that the strain-relief device should fail.
This can be ensured, for example, by making it somewhat longer and by laying it in a loop.

Note! Observe the torque values marked
on the side underneath the terminals.
If AC cables are laid over the shaft of the DC main switch or across the connection block
of the DC main switch, they may be damaged when the inverter is swung in, or they may
even prevent the inverter from being swung in.
IMPORTANT! Do not lay AC cables over the shaft of the DC main switch or across the con-
nection block of the DC main switch.
