Must it be connected to the power grid first and loaded with electrical load before it can switch to operating in island mode?
First, it should be confirmed that before operating in island mode, you were drawing power from the main grid; therefore, you can only disconnect from the main grid and switch to island mode if your generator is capable of meeting your essential power demands
Before operating in island mode, electricity was drawn from the main grid. If it is necessary to shut down the system after switching to island mode, should one inform the electrical team to reduce the load to a certain level before shutting it down?
Do you want to shut down only the machine, or all electrical devices? Only shut down this equipment while keeping the others running; contact the electrical staff to disconnect the power connection from the main network. If all the equipment stops working, and it is assumed that a fault has caused the shutdown, then it’s indicated that all the equipment has run out of power, including those used for circulating water and other utility systems; generally, this approach is not adopted :)
