Dynamic Load Management (Dlm) - LEGRAND Green'up One Installation Manual

6.2.1. Dynamic Load Management (DLM)

You can implement dynamic load management with for this purpose compatible energy meter. The figure
below shows an example how you can build up the system.
• The energy meter measures the total power consumption and the actual current per phase. If some other
load over the set maximum current for load management is added when charging is ongoing, the charger
will decrease the charging current. If the total power consumption reaches the allowed maximum power,
the charging interrupts untill the total power consumption has decreased to a value at which the charg-
ing can continue.
Other loads
• Use only current transformers which have the same serial number, they are calibrated with one another.
• 1-phase measurement: select the correct parameters in the energy meter's settings.
• Please see the energy meter instructions for more detailed information.
