Wants to know can they use conventional motor cable or will need to use a cable rated for variable speed drives?
Resolution:
Output Cable Follow the guidelines below when selecting output cable:
• Cable type: the cable selected must have a low capacitance
phase-to-phase and phase-to-ground. Do not use mineral-impregnated
cable because it has a very high capacitance. Immersion of cables in
water increases capacitance.
