*1 Remove insulation from the ends of wires to expose the length of wire shown.
*2 If you turn on the internal EMC filter, the leakage current of the drive will be more than 3.5 mA. Use these closed-
loop crimp terminals or equivalent to connect a protective ground wire that has a minimum cross-sectional area of
10 mm
