Connecting the
inverter to the
public grid (AC
side)
NOTE!
In grid configurations with neutral conductors, the neutral conductor must be
connected in order to operate the inverter.
It is not possible to operate the inverter in ungrounded grids, e.g., IT grids (insu-
lated grids without ground conductor). The grid power feed operation of the in-
verter can be adversely affected by an insufficiently dimensioned neutral con-
ductor.
▶
Make sure that the grid's neutral conductor is grounded.
▶
Ensure the neutral conductor and live conductor are the same size.
IMPORTANT! The ground conductor/grounding of the AC cable must be laid so
that it is disconnected last in the event of a failure of the strain-relief device.
Ensure the ground conductor/grounding is longer and in a loop.

Turn off the automatic circuit breaker.
Set the DC disconnector to the "Off"
switch position.
