5.2 Positioning components in the electrical distributor
The following components must be installed in the electrical distributor for the Backup-
Box:
•
Circuit breaker (miniature) | type C | 32 A
A miniature circuit breaker with type C tripping characteristics and a nominal current of
32 A must be installed
upstream of the input
for the Backup-Box.
•
Residual current device (RCD)
A residual current device must be installed
at the output
of the Backup-Box. This RCD pro-
tects against electrocution during backup operation. An RCD must be used which complies
with the respective country-specific regulations and the local network conditions.
•
In network with TT earthing: Additional residual current device (RCD) | 300 mA
In networks with TT earthing, an additional residual current device must be installed
up-
stream of the input
for the Backup-Box. An RCD with a nominal differential current of
300 mA is sufficient for this. RCDs with a nominal differential current of 100 mA or 30 mA
can also be used. A selective residual current device must be used.
5.3 Wiring components in the electrical distributor
Wire the components previously installed in the electrical distributor as shown in the
following figure.
Note:
The figure on the following page shows a connection diagram with an overview of the elec-
trical connections of a storage system with the Backup-Box. Two areas
A
and
B
are labelled
in the figure.
• The figure shows the installation of a
sonnenBatterie eco 8.0
as an example, which has
been installed in accordance with the specifications in the product documentation
(area
A
) and to which a Backup-Box has now been added (area
B
).
• In the case of a
sonnenBatterie hybrid 8.1, pro 2.0
or a
sonnenFlat
, the installation of
the Backup-Box (area
B
) is identical, but the installation of the storage system itself in
area
A
differs.
The information on the differing electrical installations can be found in the documentation
for the product in question.
