Safety Operation Aspects
Adhere to the principle of "disconnect the negative battery terminal first, then reconnect it" throughout the process. Turn off all electrical equipment before disconnection. For high-power generator installation, additionally wear insulated gloves and goggles, and never allow metal tools to touch both the terminals and the vehicle's metal body simultaneously.
High-temperature components in the engine compartment (exhaust pipe, turbocharger) must cool to room temperature before operation. Wiring of high-power generators should be kept at least 30cm away from heat sources (exhaust manifold, turbocharger) to prevent overheating and aging of the wire insulation.
A vehicle memory saver must be connected for prolonged power disconnection to prevent data loss in systems such as the ECM (Engine Control Module), instrument panel, and seat memory, which could lead to fault codes or functional abnormalities after restart.
