1) For meter wiring, please refer to Chapter 7.4.4 Meter Connection.
2) If DRM support is specified, the system may only be used in conjunction with a
Demand Response Enabling Device (DRED). This ensures that the system imple-
ments the commands from the grid operator for active power limitation at all times.
The system and the Demand Response Enabling Device (DRED) must be con-
nected in the same network. Only DRM0 is available for SMILE-B3-PLUS.
