All connected M-Bus slave devices must have unique primary or secondary M-Bus addresses depending on addressing mode used.

Measure voltage over M-Bus slave connection to verify M-Bus master connection. Voltage should be between 21-42 VDC.

M-Bus is a multi-drop 2-wire bus, with no polarity.

Use a cable of area 0.25-1.5 mm², e.g. a standard telephone cable (EKKX 2x2x0.25).
Connect the incoming wiring to the screw connector and use the screw connector for further M-Bus 2-wire bus connection.
