• Isolator can be used for dual battery common negative pole 12V or 24V system, automatic adaptation: automatic detection to adapt to the 12/24V battery voltage system, conventional two working voltage car can be directly installed, mutual installation. No need to adjust and replace. More powerful applicability
• Connect the negative electrode of the original battery with the negative electrode of the installed secondary battery with 16~50 square copper wires, and fix the isolator in a dry position, as far as possible away from heat sources, the battery isolator is not waterproof. The installation position can be close to the sub-battery for easy access and maintenance
• Use black 1.5-2.5 square wires to connect the isolator ground terminal to the common ground (car iron frame)
• Tap the reset switch, and the relay stays closed for 60 seconds after the switch is pressed, if the switch stays closed, the relay also stays closed, i.e., the two batteries stay connected in parallel. (Ground wire is provided, the remote auxiliary switch is not provided, optional) When both battery voltages are lower than 10V, the isolator can not work, and when one group voltage is 0V, the isolator can not be absorbed, which effectively protects the charger and wiring
• The first time powered on, the indicator light flashes for 5 seconds to enter into normal work, when the isolator is suction closed, the indicator light is always on; after the isolator is disconnected, it flashes once every five seconds; when it is ready to be suction closed, it lights up twice every five seconds; when the voltage is lower than 12.8V/25.6V, it is ready to be disconnected and the indicator light is dark twice every five seconds
• Suitable for RV, off-road, cruise ship, and other dual-battery systems, solving the main and secondary battery charging, discharging, and borrowing point problems
• The connecting wires of main and auxiliary batteries should be at least 16 square wires, and it is recommended to use 25 square national standard wires
• High-current dual-battery isolator for automobiles, yachts, RVs, large off-road vehicles, special equipment, solar base stations, ships, etc.
