Press the SET button a second time. The current display will flash. Use the ▲ and ▼ buttons to adjust the maximum output current limit. To enter these menus, hold down the SET

Ensure your input power supply is turned off. Connect the positive wire from your power source to the terminal. Connect the negative wire to the IN- terminal. Use a minimum of 14 AWG wire for currents up to 10A, and 12 AWG wire if you plan to run closer to the 15A maximum limit. Step 2: Load Connection
