Isolation Transformer in Grounded Power Configurations
When using an isolation transformer, attach a chassis ground wire to the neutral
connection. This grounded neutral connection does the following:
• Prevents the system from floating and avoids any high voltages that can
otherwise occur, for example due to static electricity
• Provides a solid earth path for fault conditions
Voiding of CE Compliance
The three-phase and neutral in-line filter applications that are described in
Isolation Transformer in Grounded Power Configurations
above cannot be
adequate from an EMC aspect for CE compliance. Therefore, EMC validity and
CE marking by Rockwell Automation is voided when three-phase and neutral in-
line filters are used.
IMPORTANT
Transformer (auto transformer is not supported) must have WYE secondary
with grounded neutral. Phase to neutral voltage must not exceed the input
voltage rating of the drive.
ATTENTION:
The three-phase isolation transformer and neutral in-line filter
applications that are described in this document have not been tested for EMC
by Rockwell Automation and products that are used in such installations are not
considered to have CE marking by Rockwell Automation.
If this three-phase isolation transformer and neutral in-line filter application is
used, you are responsible for EMC validation and CE marking of the system.
If CE compliance is a customer requirement, single-phase line filters, tested by
Rockwell Automation, and specified for the product must be used. See Kinetix
Servo Drives Specifications Technical Data, publication
numbers.
