1
Miniature circuit breaker | B10 – B16 (not included in scope of delivery)
2 Power meter
3 Transformer interface
4 B6 miniature circuit breaker
5 Residual current device (RCD) – 30 mA (not included in scope of delivery)
Explanations for the components:
• The miniature circuit breaker (1) protects the connection line to the storage
system.
• The power meter (2) and the transformer interfaces (3) are used to measure the
consumption and generation of power in the building.
• The miniature circuit breaker (4) protects the line that is connected to the input
for measuring the voltage of the power meter (2).
• The RCD (5) protects against high touch voltage in the event of a fault. In a TT
network you must fit a residual current operated device (5) upstream of the
storage system.
