1.2 M-Bus (optional)
The M-Bus is a galvanically isolated interface for the transmission of meter data (absolute
values).
General information about the M-Bus interface:
It is important to note that the acknowledged state of the art technology rules and the
relevant legal restraints (international and local; see "Relevant Norms / Standards /
Literature M-Bus") are to be observed.
The installation has to be performed by authorized, skilled persons.
If the regulations and the information in the installation and operating instruction manuals
are not strictly followed, or if the installation is shown to be faulty, any resulting expenses
will be charged to the company responsible for the installation.
Recommended type of cable: Telephone cable J-Y(ST)Y 2x2x0.8mm².
It is important to make sure that the topology of the M-Bus network (cable lengths and cross-sections) is suitable for the baud
rate (2400 Bd) of the end instruments.
