14.6.4 Surge Absorber

Insert a surge absorber in outside the AC reactor when viewed from the power supply unit and drive unit to prevent damage to
the control panel or power supply unit, etc. caused by the surge (lightning or sparks, etc.) applied on the AC power line. Do
not insert the surge absorber between the AC reactor, and the power supply unit and drive unit. Harmonic components occur
due to the power regeneration control.
Use a surge absorber that satisfies the following electrical specifications.
