4.7Reflected Wave Protection

When more than one motor is connected to one inverter, total wiring length should be less than 200m (656ft). Do not use a 3-wire cable for long distances. Due to increased leakage capacitance between wires, over-current protective feature may operate or equipment connected to the output side may malfunction. In case of long wire length, lower carrier frequency or contact Baldor for recommendations.
