Page 9: Display
(optical or electrical) is communicating with the meter. The communication display flashes when parametrisation mode is active. On an XC-Rack with an LMN interface, this display lights up at irregular intervals as internal communications take place to provide the data for collection by an SMGW. - Page 10 4. The phase display indicates when individual phase voltages are applied. All 3 symbols flash when the rotating field is wrong. 5. The unit shown matches the type of energy being measured or the measurement being displayed. 6. The additional cursor field displays the operating states for the meter.

Page 11: Installation And Start-Up
Installation and start-up 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 12: Mounting And Connecting The Meter
DANGER Risk of fatal injury in case of contact with live parts! In older versions up to and including those manufactured in 2023, 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. - Page 13 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.

Variants for connection of the meter DANGER Risk of fatal injury from excess voltages on the terminals of the current paths! The voltages on the terminals of the current paths must not be higher... - Page 15 a) Meter with Essailec connection system 1 - Communication interface 2 - Fibre optic interface DANGER Risk of fatal injury in case of contact with live parts! During installation of the Essailec connection system, it must be ensured that the PE connection (protective conductor) is connected first when the meter is plugged in, and that it is only removed during unplugging after the voltage connections have been disconnected.
