MBUS 2WIRE BUS

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 2x2x0.5). Connect

the M-Bus 2-wire to the screw terminals (4) and (5) or pin terminal (3).

IMPORTANT

• All connected M-Bus slave devices must have unique M-Bus

secondary or primary addresses depending on addressing mode.

• Measure voltage over M-Bus slave connection to verify M-Bus

master connection. Voltage should be between 21-42 VDC.

LED INDICATIONS

The product is equipped with a single orange LED, which shows

communication status.

Please verify your M-Bus slave conguration and connection:

• Voltage over M-Bus connection should be between 21 VDC and 42

VDC.

• All M-Bus slaves connected to the M-Bus master must have

unique primary addresses or secondary addresses depending on

addressing mode.

• Verify M-Bus slave baud rate used by M-Bus master. M-Bus master

baud rate must be identical to M-Bus slave baud rate.
