General
The Interface Module XC
meters. The module is equipped with an M-Bus (2 wires) interface. The module can be plugged
easily into the module compartment of the meter. It can be mounted or exchanged during operation
(without breaking approval seal). An integrated M-Bus interface (Protocol Converter to DIN EN
13757-3) provides a simple means of connecting multi-energy meters. This makes multi-energy
applications an affordable proposition for domestic use. Due to the communication, the modules are
suitable for a lot of control centres.
Safety Notes
The owner of the interface modules is responsible that all persons engaged on
work with the modules:
• Are competent and qualified in accordance with national regulations (see ISSA
"Guideline for Assessing the Competence of Electrically Skilled Persons").
• Have read and understood the relevant sections of the user manual.
