Page 3: Care And Disposal Information
Care and disposal information DANGER Risk of fatal injury in case of contact with live parts! Before the housing of the meter is cleaned, all conductors that the meter is connected to must be de-energised. Use a dry cloth to clean the device housing. Do not use any chemical cleaning agents! The following table names the components and how they are to be treated at the end of their life cycle. -
Page 4: Basic Safety Instructions
If the mains power fails and then returns, there is no need to do anything to the meter. Notes on correctness of measurements For the notes on correctness of measurements applicable to this meter in Germany, please see the enclosed document entitled “Notes on correctness of measurements for LZQJ-XC, DMTZ-XC and XC-RACK”. -

Page 8: Displays
Displays a) LC display 1. The operation display shows the energy direction that is currently being measured by the meter (supply/draw of active power, inductive/capacitive reactive power). If a load current is flowing through the meter, the energy direction arrow indicates which quadrant is being used for the measurement, e.g.: 1st quadrant +P/+Q 3rd quadrant –P/–Q... - Page 9 6. The additional cursor field displays the operating states for the meter. The arrows indicate whether any manipulation or an installation error was registered or if the power threshold was exceeded. The cursor is active where any manipulation of the terminal cover, meter cover or any magnetic influence is registered.
- Page 10 b) 4-line display 1. The comment text describes the displayed values in the lists as plain text. 2. The energy direction indicator indicates the direction of the measured energy (+ for obtained energy, - for supplied energy). 3. The value area displays the measured values. 4.
- Page 11 9. The symbol for reading out data appears when the data interface (optical or electrical) is used to communicate with the meter. 10. The symbol for clock controller indicates that the tariff control of the meter is performed via the internal clock. 11.

Page 12: Installation And Start-Up
Installation and start-up The meters in series DMTZ-XC are suitable for wall mounting as per DIN 43857-2. When connecting the meter, always observe the corresponding connection diagram, which you will find in the terminal cover of the meter and in your delivery documents. - Page 13 DANGER Risk of fatal injury in case of contact with live parts! S0 inputs are not potential-free. Depending on the voltage version of the device, the S0 inputs are connected electronically internally with the measuring connections or with the auxiliary voltage and are therefore not potential-free.
