PRECAUTIONS to install a low voltage battery disconnect
1. The control mode of this low voltage disconnect module: control the connection of the negative pole between the battery and the load
2. The low voltage battery disconnect has high-voltage sensitive components, so try to avoid direct contact with the metal terminals when wiring. When wiring, please use it with qualified wire and tighten it. Please fix the controller to avoid vibration.
3. When using the protector with the system, please contact customer service if you have any uncertainty parameters.
4. When testing, please use the adjustable ripple power supply with small current ripple, and test with a good method, and make sure the test voltage is idling. The voltage setting in the default parameter table can be used normally
5. The battery capacity is unlimited, it must be charged with the right battery charger and must have an anti-reverse charging function.
