PrPMC800/800ET Processor PMC Module Installation and Use (PrPMC800A/IH5)

A Specifications

Environmental Characteristics

EMC Compliance

The PrPMC800/800ET is an add-on module meant to be used in conjunction with standard

VME, CompactPCI, or ATX baseboard applications. As such, it is the responsibility of the OEM

to meet the regulatory guidelines as determined by their application.

The PrPMC800/800ET has been tested in conjunction with a standard ECC baseboard and

chassis for CE certification and meets the requirements for EN55022 Class A equipment.

Compliance was achieved under the following conditions:

❏ Shielded cables on all external I/O ports.

❏ Cable shields connected to earth ground via metal shell connectors bonded to a

conductive module front panel.

❏ Conductive chassis rails connected to earth ground. This provides the path for

connecting shields to earth ground.

❏ Front panel screws properly tightened.

For minimum RF emissions, it is essential that the conditions above be implemented. Failure to

do so could compromise the EMC compliance of the equipment containing the module.
