If there is a Space during the assembly, please straighten it before assemble it. 2. Check RD60XX: Adjust input power supply to 12v/1A to power on RD6012, and set 5V/1A output on RD60XX, turn on the output to see if the output is normal. 3. Back board assembly: install the rocker switchandAC power socketon the lower board. 4. to switch power supply: (dangerous, non-professionals should not operate); Uselongbrown cable to connect therockerswitch and the live wire (L) of the switch power supply; then useshortbrown cable to connect therockerswitch and the live wire (L) of the AC power socket; Use the blue cable to connect the neutral wire (N) ofAC power socket and the neutral wire (N) of switch power supply; 5. Use a yellow-green 2-color cable to connect the ground wire (E) of AC power socket and the ground wire (〨) of switch power supply.Use 2 red cables to connect the IN+ of the green terminal and the positive electrodes (+V),and use 2 black cables to connect the (IN-) of the terminals and negative electrodes (COM).Install the temperature sensor extension board to back panel.If need use external temperature detect, can insert external temperature sensor cable to be back end of the case,and test. Assembly step: Assemble the switch power supply: Installthe switch power supply on the lower board switch power supply test: Check the wring again and power on the switch power supply, and use test pencil to check the power and insulation status. Then use multimeter to check if the 60V output is normal, then use screw driver to adjust the output of the switch power supply toabout68V.
