ATTENTION: Risk of equipment damage exists. The drive power source type
must be accurately determined. Jumpers PE-A, PE-A1, PE-A2, and PE-B1
must be configured for the power source type according to the
recommendations in the PowerFlex 755T Input Product RF Emission
Compliance and Installation Requirements table on page 30
.
