Chapter 1 Selection Considerations
EMI Filters
The PowerFlex 755TM bus supply standard filtering is obtained by selecting
catalog code (-L) in catalog position ‘g’ (see PowerFlex 755T Product Catalog
Number Explanation on page 17). Additional EMI filtering can be ordered
with auxiliary AC line EMI filtering by selecting catalog code (-J) in catalog
position ‘g’. The (-J) option code adds ferrite cores to AC lines after the
precharge circuits. See Power Filter Jumpers
on page 26 for more information
about power filter jumper settings.
Power Filter Jumpers
The power filter jumper configuration of the PowerFlex 755TM bus supply is
an important part of your migration.
See PowerFlex 750-Series Products with TotalFORCE Control Installation
Instructions, publication 750-IN100
for detailed information about the use
and location of the power filter jumpers.
Figure 2 - PowerFlex 755T Power Jumpers
IMPORTANT The default factory settings for the power filter jumpers is; PE-A, PE-A1, PE-
A2 jumpers in the connected (IN) position and the PE-B1 jumper in the
disconnected (OUT) position. If necessary, reconfigure the power filter
jumpers as required by the power source grounding method and EMC
requirements. When the -P51 option is selected, the factory jumper settings
change.
IMPORTANT There could be multiple PE-A2 jumpers, depending on the frame size of the
PowerFlex 755TM bus supply. Each LCL Filter roll-in assembly has a separate
PE-A2 jumper. All PE-A2 jumpers MUST be in the same position.
