  • Page 5: General Description

    General description This generation G DIZ is a digital single-rate, two-rate or four-rate tariff meter for measuring positive and negative effective and reactive energy in 2, 3 and 4-wire networks. Tariff switching is performed via the internal real time clock (RTC) or an external control input.

  • Page 12: Interfaces

    Interfaces M-Bus interface The M-Bus interface is designed as per DIN EN 13757-2, -3. The M-Bus interface is galvanically isolated from the meter and is located on additional terminals 23 and 24. The following parameters can be transferred via the M-Bus: y Manufacturer identification y Medium y Primary and secondary address of the M-Bus...
  • Page 13 The data protocols used are the M-Bus protocol (see also M-Bus interface on page 12), SML (as per SML specification version 1.03) or Modbus-RTU® (Remote Terminal Unit). Properties Number of connected devices up to 32 Maximum cable length up to 1,000 m Data transfer rate 300...38400 baud, depending on the protocol...

  • Page 14: Inputs And Outputs

    The settings for the serial interface are described as the transfer mode. The following options are available: y 1 start, 8 data, 1 stop bit, even parity (8E1) y 1 start, 8 data, 1 stop bit, uneven parity (8O1) y 1 start, 8 data, 2 stop bit, no parity (8N2) y 1 start, 8 data, 1 stop bit, no parity (8N1) The transfer mode can be changed via Modbus®...
  • Page 15 The pulse value can be set to 1, 10, 100 or 1 000 pulses/kWh or pulses/ kvarh. For a meter with a configured primary pulse output, the functionality of the pulse output also depends on the set total transformer factor. Choose the transformer factors so that a sufficiently large pulse pause is ensured when the meter is under maximum load.
  • Page 16 The internal battery allows at least 250 readings with a duration of 1 min each to be performed. These readings can be performed over a period of 8 years; however, the service life of the battery can change due to the user profile.

  • Page 17: Installation And Start-Up

    Installation and start-up Mounting the meter The meter can be mounted on TH 35-7.5 cap rails as per EN 60715. The following figures show the dimensions (in mm) relevant for mounting. The device may only be used in switch and meter cabinets with a degree of protection of IP51 (or higher).

  • Page 22 4-wire version, connected to current and voltage transformers (superposed circuit with 2 current transformers) Terminal blocks ATTENTION Application of excessive torque will damage the connection terminals! The appropriate torque is dependent on the type of connection line involved and its maximum current. y Tighten the connection terminals to the corresponding torque as per EN 60999-1.
  • Page 23 DANGER Risk of fatal injury from high voltage when secondary circuits of power transformers are interrupted! In transformer connected meters, the high voltage generated on an interrupted secondary circuit of a power transformer can cause fatal injuries, and will destroy the power transformer. y Before disconnecting the current paths, short-circuit the secondary circuits of the power transformer at its testing terminals.
