Page 8: Lc Displays
LC displays a) VDEW display 1. The operation display shows the energy direction that is currently being measured by the meter (export/import of active power, inductive/capacitive reactive power). If a load current is flowing, 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 if any manipulation of the terminal cover or the 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 import, – for export). 3. The value area displays the measurements. 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 LZQJ-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! During installation or when replacing the meter, the wires connected to the meter must be de-energised. y The installer bears responsibility for coordinating the rated values and parameters of the supply-side overcurrent protection devices with the maximum rated currents of the meter.

Page 14: A) Transformer Connected Meter
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 Make sure that the screws of the connection terminals are undam- aged and smooth-running before starting the screwing process. y Tighten the connection terminals to the corresponding torque as per EN 60999-1. - Page 15 Terminal block, view from below (left), view from above 1 - Optical fibre coupling 2 - Button for manipulation detection DANGER Risk of fatal injury from high voltage when current transformers disconnected! In transformer connected meters, the high voltage generated on a disconnected current transformer can cause fatal injuries.
