Page 8: Lc-Displays
LC-displays a) VDEW-display 1. The operation indicator shows the energy direction currently measured by the meter (supply/drawing of active power, inductive/ capacitive reactive power). If there is a consumer current flowing, the energy direction arrows show in which quadrant the value is measured. - Page 9 6. In the additional cursor field the operational status of the meter is indicated. The arrows show if a manipulation or an installation error has been registered or if the power threshold has been exceeded. The cursor is active, if a manipulation at the terminal cover, the housing cover or by magnetic influences has been registered.

Page 12: Installation And Commissioning
Installation and commissioning Meter of the LZQJ-XC series are suitable for wall mounting according to DIN 43857-2. When connecting the meter, observe the appropriate wiring diagram, which you can find inside the terminal cover and as a part of the delivery docu- ments. - Page 13 DANGER! Contact with live parts is dangerous to life! S0-inputs are not potential-free. The S0-inputs are, depending on the voltage version, internally electrical connected to the measurement connections or to the auxiliary voltage and therefore potential carrying. y Observe the device-specific wiring diagram inside the terminal cover.
