🔧II .Assembly steps:
1,Battery inspection
1-1,Use a voltmeter to measure the voltage of each single battery to ensure that the voltage is within the normal range and close. If the voltage difference is large, parallel voltage equalization of the battery may be required;
1-2,Check the appearance of the battery to ensure that there is no damage, leakage, etc.
2. Assemble the face cover
2-1. Install the positive terminal and tighten the screws
2-2. Install the negative terminal and tighten the screws
2-3. Install the cigarette lighter female socket
3-4. Install the PD+QC3.0 interface
2-5. Install the Anderson charging interface (50Ah)
2-6. Insert the Anderson negative wire (black) into the negative terminal of the cigarette lighter female socket and the negative terminal of the PD+QC3.0 interface respectively
2-7. Insert the Anderson positive wire (red) into the positive terminal of the cigarette lighter female socket and the positive terminal of the PD+QC3.0 interface respectively
2-8. Install the display screen and insert the display screen cable
🔧III. Assemble the body of the 12V outdoor power supply
3-1. Install EVA and epoxy board
3-2. Place the battery and pay attention to the placement direction of the battery
3-3. Install the baffle
3-4. Insert the connecting piece with a cap and correctly connect it to the battery post. Place the M6 nut
3-5. Connect the flat cable. The negative wire (black) is connected to the total negative pole of the battery. The positive pole (adjacent to the negative wire) is sequentially connected to the positive poles of the batteries (Figure 18).
3-6. Install the metal strip (protection board bracket) and tighten the screws
3-7. Test the voltage to ensure the connection is correct
3-8. Install the protection board and tighten the screws
3-9. Install the “B-” wire (short) of the protection board and connect it to the total negative pole of the battery
3-10. Install the “P-” wire (long) of the protection board and tighten the screws
3-11. Close the face cover and tighten the screws
3-12. Connect the positive wire to the total positive pole of the battery and connect it to the positive terminal of the Anderson positive wire, and then tighten the screws
3-13. Connect the Anderson negative wire to the positive terminal of the “P-” wire of the protection board, and then tighten the screws
3-14. Insert the flat cable socket into the corresponding port “B+B8B7B6B5B4B3B2B1B-” position of the protection board
3-15. Insert the display screen cable into the corresponding (display screen) port marked on the protection board
3-16. Insert the temperature wire into the corresponding (temperature) port marked on the protection board and tidy it up
