should preferably be the connection point for internet,
but this is not a requirement. Any unit of the group can
be defined as internet gateway/communication master.
The connection group is also defined by a maximum
current, which is typically the same size as the fuse that
is to be protected from overload.
The connection group either consists of either 1 or
several charging station(s), where the real current is
calculated as the sum of all charging station currents, or
several charging stations together with other loads. If
the connection group consists of other loads as well,
then the real current needs to be monitored, using a
load interface. The load interface acts as DLM master of
this connection group. The charging stations (and
possible subgroups) will share the remaining current
(unused fuse capacity) to prevent overload.
The real current is measured by current transformers or
energy meter, and transferred into the system with a
load interface. It is possible to define several connection
groups as a hierarchy of maximum four levels.
NOTE
Internet connection is necessary for configuration but
not for operation.
