EMC-CS-2009.1

February 11, 2010

8.0 Conducted RF Emissions: CE 420

These requirements are applicable to the following component categories:

Electronic Modules: A, AS, AM

Shall meet Average Limits only.

Electronic Modules: AX, AY

Shall meet both Average and Quasi Peak Limits.

Electric Motors: EM

Shall meet both Average and Quasi Peak Limits.

Electronic Motors: BM

Shall meet Quasi Peak Limits only

These requirements are not applicable for electric motors/actuators that operate with intermittent duration AND with direct

operator control via depression of a switch unless packaging requirements place the motor and/or it's wiring within 500mm of

the vehicle's radio antenna. The FMC EMC department shall review and approve application of these requirements to these

devices prior to commencement of testing.

These requirements may be relaxed or waived for components having a shielded power and power return wiring system

implemented with shielded cable or by placement of multiple components in a common shielded enclosure. However this

requires prior approval by the FMC EMC department upon their review of testing and/or analysis demonstrating that the "in-

vehicle" packaging will not introduce alternate paths for coupling of conducted emissions exceeding CE420 levels on to

unshielded power and return circuits.

8.1 Requirement

Conducted RF voltage emissions on the component power and power return circuits shall not exceed the requirements listed

in Table 8-1. Requirements are limited to Long Wave (LW), Medium Wave (i.e. AM) and FM broadcast services.
