[Installation of Noise Filter and Surge Protector on DC Power Supply for Motor Drive]
For the wires to be connected to the power connector, use the following applicable wires.
Caution
Leak current may vary depending on the motor capacity, cable length and ambient
temperature.
Therefore, it is required to measure leak current at the point of the leakage breaker
installed when leakage protection is to be conducted.
A clear purpose is necessary when selecting a leakage breaker such as to protect from
fire or protection of personnel. For leakage breaker, use a high frequency applicable type
(for inverter).
