First, confirm complete power cut before any replacement operation. You need to turn off the electric forklift’s main power switch, disconnect the battery assembly, and wait at least 10 minutes to release residual current stored in the internal circuit, to eliminate potential electric shock risks during subsequent disassembly work.
Second, verify all key parameters of the old DC contactor before selecting new replacement parts. You need to record the rated working voltage, rated current load, mounting hole spacing, wiring terminal size of the original component, to make sure the new part fully matches the operation requirements of your electric forklift unit. Mismatched parameters may lead to insensitive switch action, abnormal circuit heating or even unexpected power failure during operation.
Third, operate in strict accordance with the standard process during installation. Do not adjust the connection order of main power cables and signal wires arbitrarily, refer to the original circuit marking to connect each wire correctly, and fasten all wiring screws to the recommended proper torque. Over loose connection will cause high temperature ablation of terminals, while over tight force may damage the thread structure of the contactor base.
Fourth, perform no-load commissioning after installation. Do not put the forklift into heavy load operation immediately. Repeatedly test the walking, lifting and other functional actions of the forklift, confirm the DC contactor switches sensitively with no obvious abnormal noise or overheating phenomenon, then the whole replacement process is completed safely.
