Mechanical and electrical installation
The METERS and METERL load management systems can be used flexibly for the total current measurement of a sys-
tem or for section current measurement within a system.
Total current measurement
For total current measurement, the cable type current transformers are installed on the individual phases of the house
supply line and the energy meter on the house connection.
This measurement takes into account both the building load and the consumption of the charging stations.
WARNING!
Approval requirement by the grid operator
Please note that the position of the energy meter for total current measurement may have to be approved by your
local grid operator.
Contact your local grid operator for further information!
Section current measurement
In contrast, with section current measurement, the cable type current transformers are installed behind the tap for
the charging stations, and the energy meter can be installed nearby in a distributor in the building.
This measurement only takes into account the building load, and not the consumption of the charging stations.
WARNING!
Correct specification of the measurement situation
In order to correctly identify the meter values, the meter position must be specified correctly when setting up the
load management system via the
ABL User Interface
software (see page 26).
