	Dynamic load management (DLM) is a sophisticated feature that empowers users to efficiently control electric load by managing a group of chargers installed within a single circuit. Through the implementation of Modbus RS-485 communication, the chargers are able to communicate with one another and dynamically adjust their charging power in response to the load on the grid, ensuring optimal charging operations and grid stability.		Dynamic load management (DLM) is a sophisticated feature that empowers users to efficiently control electric load by managing a group of chargers installed within a single circuit. Through the implementation of Modbus RS-485 or TCP/IP communication, the chargers are able to communicate with one another and dynamically adjust their charging power in response to the load on the grid, ensuring optimal charging operations and grid stability.

	Dynamic Load Management (DLM) is achieved through a carefully interconnected system of chargers, where communication is governed by a designated "Primary" charger, dictating instructions to the remaining "Secondary" chargers. These chargers must be interconnected serially (daisy chained), each requiring the use of UTP twisted pair cables for communication via the A and B pins.

	It is very important to set ''max power from grid'' parameter correctly in the '''PRIMARY''' charger if you want to use DLM. This parameter shows how much current you have in the circuit you want to balance. That means you have to set all available amperes.		It is very important to set ''max power from grid'' parameter correctly in the '''PRIMARY''' charger if you want to use DLM. This parameter shows how much current you have in the circuit you want to balance. That means you have to set all available amperes.

	If ~~for example~~ in the ~~Primary~~ charger ~~you will set lower current~~, DLM might not work correctly and the chargers might not even start the charging process.		If a lower current is set in the primary charger, DLM might not work correctly and the chargers might not even start the charging process.

	For the secondary chargers, this parameter is not as critical. It is advisable to set it to a maximum of 16 A (for 11 kW chargers) or 32 A (for 7.4/22 kW chargers).
