    User Manual 3-3-4 Earth terminal PE For safety's sake, earth terminal PE must be well grounded to reduce noise. Please use the standard ground lead which should be as short and thick as possible (its grounding impedance should be no more than 10Ω). Do not connect its ground lead with that of a high-current loading machine to the ground at the same time, for example, welder or high-power motor, they must be grounded separately.

    User Manual Multi-core shielded cable or stranded wire should be used to connect control terminals. The terminal which is closed to the converter must be connected to earth terminal PE. When wiring, the control cables must be kept away from the main circuit and high-current circuit by at least 30cm. Instead of parallel wiring, vertical wiring should be adopted to prevent the drive from malfunctions resulting from external interference.
