Verify Power Jumper Configuration

PowerFlex 750-Series drives contain protective MOVs and common mode capacitors that are referenced to ground. To
guard against drive damage and/or operation problems, these devices must be properly configured.
A properly configured drive has all jumpers connected or all jumpers disconnected, depending on whether the power source is

solid grounded or non-solid grounded. If jumpers are not all connected or all disconnected, the power jumpers are not properly
configured. The drive power source type must be accurately determined and the jumpers must be configured for the power source.

Verify I/O Wiring

To properly configure a drive, you need to know the source of the speed reference and the start/stop commands. There are
three places where signal sources (such as push buttons and potentiometers) are connected to the drive.
1. The drive's main control board.
• Terminal block TB1 on a PowerFlex 753
• Embedded EtherNet/IP port on a PowerFlex 755
• Terminal block TB1 on a PowerFlex 755 Di0
2. An expansion I/O module.
3. A communication network module.
The drive can always be controlled by the HIM for speed, start, and stop control. If that is the case for operating conditions, proceed
