Connecting the
inverter to the
public grid (AC)
IMPORTANT!
-
Form loops with the AC cables when connecting them to the AC terminals.
-
When securing the AC cables using a metric screw joint, ensure that the
loops do not protrude beyond the connection area.
Otherwise, under certain circumstances it may no longer be possible to close the
inverter.
IMPORTANT!
-
Make sure that the grid's neutral conductor is grounded. This may not be the
case for IT grids (insulated grids with no earthing); it will then not be possible
to use the inverter.
-
The neutral conductor must be connected in order to operate the inverter. A
neutral conductor that is too small may adversely affect the inverter feeding
energy into the grid. The neutral conductor must have an amperage of at
least 1 A.
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.

The fastening screw must also be
tightened for an unassigned ground
conductor (PE) connection.
IMPORTANT! Observe the torque val-
ues marked on the side underneath
the terminals.
