Controller load terminal can connect to DC power equipment which rated working voltage the same as the battery rated working voltage, controller will power up the load using battery voltage
Connect the positive and negative electrode of load to the load connection terminal. load terminal may have voltage, so when you wiring, please carefully, avoid cause short circuit. We suggest connect a safety device on the positive electrode lead or negative electrode lead. During the installation, don’t connect to safety device. After installation, make sure all the wiring are correct, then connect to safety device. If the load connection through switchboard, each load circuit should individual connect safety device, all the load current is not higher than the rated current 10A of controller.
