ABB ACS880 - Additional Notes; A Drive Larger than 500 Kva with an IGBT Supply Unit or a Regenerative Rectifier Unit

￭ Additional notes
A drive larger than 500 kVA with an IGBT supply unit or a regenerative rectifier unit
Use a two-winding transformer dedicated to drives and motors. Alternatively, use a
three-winding transformer, and connect only drives and motors to the same secondary
winding.
WARNING!
Do not connect capacitive load (for example: lighting, PCs, PLCs, small power
factor compensation capacitors, etc.), to the same transformer secondary winding
with drive. It can cause current resonances which can damage the equipment.
