Input Power Conditions
Input Power Condition Corrective Action
Low Line Impedance (less than 1% line reactance) • Install Line Reactor
(2)
• or Isolation Transformer
(2) See Appendix B of the PowerFlex 520-Series Adjustable Frequency AC Drive User Manual, publication 520-UM001 for accessory ordering information.
Greater than 120 kVA supply transformer
Line has power factor correction capacitors • Install Line Reactor
(2)
• or Isolation Transformer
Line has frequent power interruptions
Line has intermittent noise spikes in excess of 6000V (lightning)
Phase to ground voltage exceeds 125% of normal line to line voltage • Remove MOV jumper to ground.
• or Install Isolation Transformer with grounded secondary if necessary.
Ungrounded distribution system
240V open delta configuration (stinger leg)
(1)
(1) For drives applied on an open delta with a middle phase grounded neutral system, the phase opposite the phase that is tapped in the middle to the neutral or earth is referred to as the “stinger leg,” “high
leg,” “red leg,” etc. This leg should be identified throughout the system with red or orange tape on the wire at each connection point. The stinger leg should be connected to the center Phase B on the
reactor. See Appendix B of the PowerFlex 520-Series Adjustable Frequency AC Drive User Manual, publication
520-UM001 for specific line reactor part numbers.
