power factor improvement effect, but also may cause capacitor abnormal heating. Therefore, never
install a phase leading capacitor.
• Keep power imbalance within 2% of the supply rating. Large imbalance will shorten the life of the
smoothing capacitor.
• Introducing with a missing N-phase or with a mistaken N-phase will break the equipment.
