6.2 Placing components in the distributor
„
Mount the following components necessary for electrical connection of the storage
system in the electrical distributor.
Up to 23 cm of free space on one mounting rail is needed for the components.

1 Miniature circuit breaker B20/B25
2 WM271 power meter
3 Transformer interfaces
4 Miniature circuit breaker (B6) for power meter (not included in scope of delivery)
5 Residual current device (not included in scope of delivery)
Explanations for the components:
• The miniature circuit breaker (1) protect the mains line of the storage system.
• The power meter (2) and the transformer interfaces (3) are used to measure the con-
sumption and production of power in the building.
• The power meter is protected using a type B6 miniature circuit breaker (4). An additional
miniature circuit breaker can be avoided if there is already an appropriate circuit breaker
(see Connecting the power meter [P. 36]).
• A residual current circuit breaker (5) must be installed in networks with TT earthing. An
RCCB with a rated differential current of 300 mA is sufficient for this. RCCBs with a
rated differential current of 100 mA or 30 mA can also be used. This has been tested un-
der DIN EN 62640-1:2008/A1:2013; country-specific requirements must be observed in
each case. The type of RCCB must be selected depending upon the local conditions of
the public electricity grid.
6.3 Wiring the components and storage system
„
Wire the components previously placed in the electrical distributor. Follow the instruc-
tions in the
following sections for this.
The figures in section Electrical connection overview [P. 32] show the building installation
after all components have been fully connected.
