As the applicable voltage of this controller exceeds the safety voltage of human body, please read the instructions carefully before operation and operate this controller only after the safety operation training is completed.2. There are no parts in the controller that need maintenance or repair. Users should not disassemble and repair the controller by themselves.3. Please install the controller indoors to avoid exposure of components and prevent water from entering the controller.4. Please install the controller in a well ventilated place. The temperature of the heat sink will be very high during operation.5. It is recommended to install a suitable fuse or circuit breaker outside the controller.6. Before installing and adjusting the wiring of the controller, be sure to disconnect the wiring of the photovoltaic array and the fuse or circuit breaker near the battery terminal.7. After installation, check whether all line connections are tight to avoid the danger of heat accumulation due to virtual connection.
