Modbus energy meters
7.2.4.11 Function test for the electrical wiring connections
The energy meter must be connected to the voltage supply and a
load must be connected. This function can only be used if the power
factor of the installation is between 0.6 and 1 and minimum current
consumed on each phase = 20 % In.
Press and hold button B for at least 3 seconds.
The messages below indicate you the connection status of phases
in the meter device.
Press button B for at least 3 seconds to exit this mode.
