3.2. Supported System Types The Energy Meter Series has a number of different possible system wiring configurations (see Section 4, Wiring). To configure the meter, set the System Type via the User Interface or Modbus register 130 (if so equipped). The System Type tells the meter which of its current and voltage inputs are valid, which are to be ignored, and if neutral is connected. -
