Electromagnetic Compatibility
General Guidelines
Refer to Appendix E, “Electromagnetic Compatibility Guidelines for
Machine Design” for an in-depth discussion of electromagnetic
compatibility (EMC) and electromagnetic interference (EMI).
European Union EMC Directives
The ULTRA 100 Series drives are designed and tested to meet the
European EMC Directive. Declarations of conformity, which
enumerate the standards used, are included in the manual.
Installation requirements necessary to meet this directive are:
1. Use of factory supplied cables,
2. Use of an external AC line filter, and
3. If an external supply powers the I/O, grounding of this power sup-
ply is required.
Refer to Appendix A, “Options and Accessories” for part numbers.
The following diagrams show the mounting dimensions for single
phase AC Line Filters available from Rockwell Automation.
Table 5.3 shows a typical filter selection matrix for ULTRA 100
Series drives. All the filters identified below are manufactured by
Schaffner or Roxburgh and are widely available. There are many AC
line filter manufacturers whose filters can be successfully integrated.
Rockwell Automation recommends Schaffner or Roxburgh filters
based on our test results, but the machine builder is responsible for the
suitability of the filter selection in a specific application. These filters
can be used for distributing power to multiple drives, rather than using
an individual filter for each drive. Further information is available
from Schaffner (1-800-367-5566) or Roxburgh (01724.281770
[011.44.1724.281770 from the USA]).
AC line filters for use with ULTRA 100 Series drives are listed in
Table 5.3.

Intro
ATTENTION: Large leakage currents exist in AC line
filters. They must be grounded properly before applying
power. Filter capacitors retain high voltages after power
removal. Before handling the equipment, voltages should
be measured to determine safe levels prior to handling the
equipment. Failure to observe this precaution could result
in severe bodily injury.
