•
The conductive shielding layer of cable should be grounded to the metal part of both units.
•
Never use multi-core cable
•
As this unit is equipped with an inverter, to install a phase leading capacitor not only will deteriorate
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.
