To activate load balancing, 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 2.
The energy meter continually measures the total energy consumption for each phase. The
data is transmitted to the wallbox, reducing the charging current in order to prevent the
main fuses from tripping. When using a single-phase wallbox, a single-phase energy
meter must be installed to the phase to which the wallbox is connected.

During installation, the amperage of the DIP switch SW1(1-2-3) must be adjusted to
correspond with the size and strength of the main fuses.
The DIP switch SW2(1-2-3-) which controls the charger's maximum permitted charging
current should be set to the recommended current values outlined below, when load
balancing for individual chargers is activated.
The energy meter is connected to the "E-meter" printed circuit board connection block.
If the wallbox has an internal energy meter installed, the Modbus connection of the
external meter is to be connected in parallel with the internal one.
