IMPORTANT PowerFlex 750-Series drives, Frames 1…7, leave the factory with jumpers
PE-A and PE-B in one of two possible configurations. Reconfigure these
jumpers based on the power source type available.
Cat. No. Position 11 Jumper PE-A
(MOV/Input filter caps)
Jumper PE-B
(DC bus common mode caps)
A Connected Disconnected
J Connected Connected

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
in Table 45
.
Power Source Type Jumper PE-A
(1)
(2)
(MOV/input filter
caps)
(1) When MOVs are disconnected, the power system must have its own transient protection to confirm known and controlled
voltages.
(2) Frame 5…7 common DC input drives do not have the PE-A jumper.
Jumper PE-B
(DC bus common
mode caps)
Benefits Of Correct
Configuration on Power Source
Type
Non-Solid Ground
• AC fed ungrounded
• Impedance grounded
•B phase ground
• DC fed from an active
converter
Disconnected Disconnected Helps avoid severe equipment
damage when ground fault occurs
Solid Ground
• AC fed solidly grounded
• DC fed from passive
rectifier that has a solidly
grounded AC source
Connected Connected • UL compliance
• Reduced electrical noise
• Most stable operation
• EMC compliance
• Reduced voltage stress on
components and motor bearings
