2. Installation of Power Harness
A spare power line is needed for the extension of the power line if it’s not long enough. The positive
terminal buckle of the power line must be screwed to the positive terminal of the relay, and the
negative terminal to the cathode of the battery. Note that the voltage should be 24V. Pay attention to
the harness to avoid direct contact with hot objects.
3. Installation of Smart Main Harness
It is required to arrange the smart main harness in concealed locations in the cab, which does not
affect the operation of the excavator. The smart harness main switch should be installed in a position
convenient for operating as required.
