7.2.3 Mounting Solar Inverter
1. Attach the solar power inverter to the mounting plate, see
Fig.
7.5, p. 28.

plate
2. Secure the solar power inverter to the mounting plate by
fitting the washers and mounting nuts on the stud bolts and
then tightening (see
Fig. 7.4, p. 27, item C
). (The stud bolts
are also used for connecting the grounding cable to the solar
power inverter.)
3. Check the installation.

Physical installation of the solar power inverter is now com-
plete.

Danger of death or severe injuries from dan-
gerous voltage
► Disconnect the AC conductor from power
before removing or inserting the AC plug.
7.3.1 General Instructions
The solar power inverter is connected to the local power grid with
an AC connection, see
Fig. 7.6, p. 28.
Fig. 7.6:
Location of AC connection
The round AC plug has a coupling to protect against accidental
removal. This coupling can be disengaged with a screwdriver.
Use a flexible triple-core cable (L, N, PE) with a conductor cross-
section from 2.5 to 4.0 mm² (coefficient k=1).
Observe the required grid impedance at the grid connection point
(cable length, conductor cross-section).
Select the cable length and conductor cross-section so that the
conductor temperature and cable losses are as small as possible.
In some countries (e.g. France and Germany), specific require-
ments must be met for system installation (UTE C15-712-1, VDE
0100 712). These requirements specify the minimum cable cross-
section and the protective measures required to prevent overheat-
ing due to high currents. Always adhere to the specific require-
ments of your country.
The energy meter must be installed between the solar power
inverter and the grid feed-in point. Observe the directives of your
local electricity supplier when doing this.
The following table shows the maximum permissible trigger current
for the automatic circuit breaker (type B).

The AC and DC sides of the solar inverter are electrically isolated.
This makes it impossible for DC electricity to reach the AC side of
the inverter, i.e., a type A residual current device is sufficient. We
