Mechanical and electrical installation | 13
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).

The energy meter supplied with METERS|METERL supports other connection types in principle, although these
are not required in practical use as a load management system. Therefore, always make sure that the energy me-
ter is set to the appropriate connection option in the SYS menu.
“Setting up the energy meter” on page20
Installation guidelines
Depending on the type of current measurement (total or section current) and the connection mode selected, the fol-
lowing guidelines should be observed when installing the current transformers and the energy meter:
Be sure to observe all local regulations for electrical installations, fire prevention and accident prevention.
All guidelines for the installation of low-voltage systems in accordance with IEC 60364-1 and IEC 60364-5-52
apply.
Depending on the type of current measurement, the cable type current transformers are attached to the individual
wires of the house supply line (total current measurement) or the sub-distribution unit for the building (section
current measurement).
The cables for connecting the current transformers determine the maximum distance to the energy meter and thus
the position in the distribution box.
Fused taps (F = 315mA) must also be provided in the distribution box to supply power to the energy meter.

Installation of the energy meter and the cable type current transformers | 15
Installation of the energy meter and the cable type current transformers
The energy meter and the current transformers must be installed in a distribution box. Depending on the position of
the current measurement, you will need to use the distributor for the house supply line (total current measurement) or
the sub-distributor for the building (section current measurement).
The energy meter is a standard top-hat rail module that can be placed on any DIN rail. The distance between the en-
ergy meter and the current transformers is determined by the length of the connection cables that are permanently
connected to the current transformers.
You will need the following tools and components for the installation:
Phillips screwdriver Optional: Cable tie
(1 per transformer)
DANGER!
Dangerous electrical currents
Always observe the 5 safety rules:
1Cut power source
2Secure all cut-off devices
3Verify absence of voltage
4Ground and short-circuit
5Cover or bar access to adjacent components under voltage
WARNING!
Electrical installation guidelines
The entire installation must be carried out by a qualified specialist electrical contractor!
The electrical supply cable must be disconnected from the power supply during the entire installation.
The connection to the electricity grid must only be established after the installation has been completed in
order to subsequently set up the energy meter (see “Setting up the energy meter” on page19).
Proceed as follows:
1 Switch off the power supply to the house before
the distributor.

Data connection with the controller of a group installation
The energy meter must communicate with the controller charging station/control unit via its RS485 interface for the
system’s load management. The Modbus interface depends on the year of manufacture – on older ABL charging sta-
tions it is designed with spring terminals and on newer models it is equipped with RJ45 sockets. METERS|METERL
are compatible with both systems.
Cat 5e or Cat 6 data cables with a cross-section of at least 0.14mm² are recommended for the wiring. The internal
twisting must be maintained until connection to the respective terminal.
NOTE
Communication via the free interface
In the controller of a group installation, one of the two Modbus interfaces remains unassigned, while the other is
used for communication with the extender charging stations.
Wire the free interface in the controller to the RS485 interface of the energy meter.
Connect the interfaces as follows:
