KD-504 | 22355 | EN | X00
2 Power meter WM271
3 Transformer interface
4 Residual current device (RCD) | Type B | 30 mA (not included in scope of deliv-
ery)
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 consumption and generation of power in the building.
• The inverter of the storage system can cause a current with DC components.
The RCD (4) protects against high touch voltage in the event of a fault. A RCD
Type B with a rated differential current of 30 mA must be installed.
The power meter wiring shown here corresponds to the standard measuring
concept for hybrid storage systems (Setup 2 in the commissioning assistant).
„ Wire the components previously placed in the electrical distributor like it is
shown in 'Circuit diagram overview – electrical connection at single-phase
mains [P. 28]' or 'Circuit diagram overview – electrical connection at three-
phase mains [P. 29]', depending on whether it is a single-phase or three-
phase network.
