Wiring instructions:
power cable
B-:Connect to battery negative (Black cable 12AWG L=150±5mm)
P-:Connect to negative of discharge port (Blue cable 12AWG L=150±5mm)
C-:Connect to negative of charge port (Black or Yellow cable 14AWG L=150±5mm)
Voltage monitoring cable
cable type:UL1007 22AWG L=300±5mm
B-(Black),B7+(Red)
B-(GND)/B1/B2/B3/B4/B5/B6/B7 (B+)
Remarks:
Please connect B- line firstly, and then connect voltage monitoring wiring harness. The last step is to connect charge and discharge lines. If you want to remove them, the order should be reversed. Please pay attention to the connection order, or it will damage the component.
