To activate load balancing in a group, a GARO Modbus energy meter must be installed
in the supply distribution box. The following energy meters are approved:
• GNM1D-RS485 (single-phase Modbus)
• GNM3D-RS485 (three-phase Modbus)
The meter's Modbus address must be set to 100.
The energy meter continually measures the total energy consumption for each phase.
Data is transmitted to the first wallbox (GLB Master), which controls the charging current
per phase for the entire system in order to prevent the main fuses from tripping. When
using a single-phase energy meter, the meter must be set to the same phase as all of the
wallboxes.
A maximum of 32 wallboxes may be connected by a shielded twisted pair cable, which
is connected to the wallbox connection block labelled ‘Data Link’.
It is not permitted to form a cascade from a box which leads out to the charger using one
or more parallel connected drop cables. See the installation example to the right.
The Data Link cable must be electrically terminated in the first and final wallboxes, via
DIP switch SW1 (DIP6) on the printed circuit board. In the below example, the SW1 (DIP
6) DIP switch is to be set to ‘ON’ in wallboxes no. 1 and 5, and ‘OFF’ in the remaining
boxes.
To verify that the master wallbox is defined as master, ensure the SW1 switch (DIP 5) is
set to ‘ON’ mode.

Example of installation – Data Link, permitted connection via external junction

It should be noted that SW1 (DIP 1–3) does not have a function for group load
balancing. Instead, group balancing is performed in the GLB Master's web interface (see
section entitled Load balancing settings in the web interface).
