General
Upgradable for future communication needs: flexible remote communication modules without breaking
approval seal. The new series of modules for domestic use puts promises into practice, paving the way not
only for multi-energy applications but also for new services in personal energy management.
This specification details the operation and the electrical requirements for connection of an AMR module
with M-Bus interface to the L+G E350 (ZxF series 100) meter.
Functions
The AMR interface contains the following functions:
 Bi-directional communications: an integrated M-Bus (2 wires, passive) interface provides a simple
means of connecting multi-energy meters. This makes multi-energy applications an affordable
proposition for domestic use. Transmission protocol: IEC 62056-21
 Rate input for tariff switching via external control inputs
 Pulse output (with pulse rate change)
 Internal communication interface for the transfer billing data between the meter and AMR module
(every 10 seconds).
For details of the communications protocol, refer to the software interface specification (IEC
62056-21 and OBIS Codes).
 Phase connections to one phase (230VAC)
Safety Notes
The owner of the AMR 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.
• Strictly observe the safety regulations (according to the following section) and
the instructions in the individual chapters.
The owner of the modules is also responsible for:
•
The protection of persons.
•
The prevention of material damage.
•
The training of personnel.
The following safety regulations must be observed at all times:
•
Devices which have fallen down should not be installed, even if no damage is apparent, and should
be returned for testing to an authorised service centre (internal damage possible).
•
Modules must never be cleaned with running water or high pressure devices. Water can cause
short-circuits or damage el. components.
