1. Mounting of M-Bus Master
By means of the enclosed angle/wall
bracket you can mount the M-Bus Master
on e.g. a wall. Use the bracket as a tem-
plate to mark the position and drill two
6 mm holes. Screws and rawlplugs are
supplied together with the M-Bus Master.
2. Power supply
The M-Bus Master is to be connected to
230 VAC. The unit has protection class II.
The connection is established by means
of a 2-wire cable through the cable bush.
Furthermore, we refer to national installa-
tion regulations.
3. Electrical connection
Dismount the top part of the M-Bus
Master by unscrewing the two screws at
the sides. Lift off the top part carefully.

marked POWER is constantly lighted.
The light emitting diode marked
OVERLOAD will be lighted for approx.
5 sec. The voltage measured on terminals
