Warning
The requirements of the net provider need to be full filled.
Selective hedges have to be used according requirements of the net providers.
Attention!
Damage of the terminals due to high torque
The specified maximum torques must not be exceeded!
Ensure that the connected lines are fixed with the needed torque compliant to EN 60999 for a safe connection. The needed torque depends on the type of used lines and the maximum current.
3.3 Protection Housing
As indicated in image 11 the cover of the terminal blocks can be sealed after installation. The assembled meter base and meter cover will be protected against unauthorized opening with a manufacturer label (format 8×20 mm, corner radius 0.5 mm) on both sides of the housing. Important
Warranty and accuracy are void if sealing labels are removed.

Functionality

8.1 Measurement
The meter measures three phase active energy with accuracy class B.
The meter provides registers for total import, total export and net energy.
Additionally, each phase L1, L2 and L3 for import and export energy are measured.
The measurement of the energy is based on the measured power according the following calculations:
Ptotal = PL1 + PL2 + PL3
Ptotal> 0: counting energy for +A
Ptotal< 0: counting energy for -A
8.1.1 Instantaneous parameter measurements
The instantaneous values can be read out via RS485 interface.

• Voltage and current
• Power factor
• Active power
• Frequency

8.2 Display Modes
The meter support three different display modes:
– AUTO Mode
– ALT Mode
8.2.1 Status Diagram No Button pressed t > ns: the parameter n can be set via data interface
10 Status diagram display mode
After power on the meter shows for 2s self-check status and goes on to the AUTO-Mode.
With the user buttons it can be changed between the different modes.
8.2.2 AUTO Mode and ALT Mode
In the AUTO Mode and ALT Mode all values which may be used for energy are displayed. This part of the display list can’t be changed by the user with any interface of the meter.
The display lists can be expanded with additional values by the user via the RS485 interface and a parameter setting program. Each list can have 32 entries.
The different values are displayed with the following formats and units:

Tab. 7: Format/Unit Displayed Values
In the AUTO Mode the next value of the defined list is displayed automatically with a settable time period.
In the ALT Mode the next value is displayed after a user button was pressed.
8.3 Fatal Error
The meter has implemented a self-monitoring system. If the meter recognizes improper operation so that billing relevant values may not be used anymore it displays “–FF–” This status will be indicated with current display items flashing (1Hz).
8.4 Backlight EV3
Backlight will be on after pressing button, it’s useful to read meter through LCD when it in dark environment. Light on time is configurable from 5s to 60 seconds.
The back light will be turned off unconditionally if the voltage is less than 0.8Un.

RS485 Interface & Registers

Default Modbus settings:
Baud rate = 9600 (settable)
Device Address = 1 (settable)
Parity = Even (not settable)
Registers are listed in document 9AKK107991A9529
