Installation Instructions
DLM reduces charging current when demand of current elsewhere increases. Simple to say, the GLB
Wallbox balance the charging current that you will get as much power as possible to the EV that is
available in the system without any risk to overload the mains fuses.
The following energy meters are approved:
• GNM1D-RS485
• GNM3D-RS485
• GNM3T-RS485 (current transformer 3-phase. Max current is based installed current transformer)
• CG EM 112
• CG EM 270
• CG EM 271
For use in systems with local electricity produktion (solar-, wind etc)
• GNM3D-LP RS485
• GNM3T-LP RS485N (current transformer 3-phase. Max current is based installed current
transformer)
Note the energy meter’s Modbus address must be set to 2, 100 or 101.
Adress 2: Recommended for a stand alone GLB Wallbox. Setting for SW1 CC2 is valid and charging
process are paused if available current drops below 6A.
Adress 100 or 101: Only recommended when multiple GLB Wallbox are connected in a grid.
Minimum charging current is 6A and charging process is not terminated by the DLM function. This
mode require an installed wifi module.
The energy meter continually measures the total energy consumption for each phase. The data is
transmitted to the GLB Wallbox, that then is reducing the charging current when necessary in order to
prevent the mains fuses from tripping.
In one-phase systems, the energy meter needs to be installed to same phase as the GLB Wallbox.
