ATTENTION: Allow only qualified personnel familiar with adjustable frequency AC drives and associated machinery to plan or implement the installation, start-
up, and subsequent maintenance of the system. Failure to comply can result in personal injury and/or equipment damage.
ATTENTION: To avoid an electric shock hazard, verify that the voltage on the bus capacitors has discharged completely before removing/installing jumpers.
Frames 1…7
Measure the DC bus voltage at the following points (see the PowerFlex 750-Series AC Drive Installation Instructions, publication
750-IN001 for locations):
• Measure the DC bus voltage at the power terminal block by measuring between the +DC and -DC terminals or between the +DC and -DC test point sockets if
equipped.
• Also measure between the +DC terminal or test point and the chassis, and between the -DC terminal or test point and the chassis.
The voltage must be zero for all three measurements.
Frames 8…10
Measure the DC bus voltage at the DC+ and DC- TESTPOINT sockets on the front of the power module (see Installation Instructions for location).
ATTENTION: This drive contains ESD (Electrostatic Discharge) sensitive parts and assemblies. Static control precautions are required when installing, testing,
servicing or repairing this assembly. Component damage can result if ESD control procedures are not followed. If you are not familiar with static control
procedures, reference an applicable ESD protection guide.
ATTENTION: Risk of equipment damage exists. The drive power source type must be accurately determined. Jumpers PE-A, PE-A1, PE-A2, and PE-B must be
configured for the power source type according to the recommendations shown in the following table.
