European Union Directive 89/336/EEC requires that this apparatus comply with relevant ITE
EMC standards. EMC compliance demands that this apparatus is installed within a CompactPCI
enclosure designed to contain electromagnetic radiation and which will provide protection for the
apparatus with regard to electromagnetic immunity. This enclosure must be fully shielded. An
example of such an enclosure is a 6U EMC-RFI CompactPCI System chassis, which includes a
front cover to complete the enclosure.
The connection of non-shielded equipment interface cables to this equipment will invalidate
European Free Trade Area (EFTA) EMC compliance and may result in electromagnetic
interference and/or susceptibility levels that are in violation of regulations which apply to the
legal operation of this device. It is the responsibility of the system integrator and/or user to apply
the following directions, as well as those in the user manual, which relate to installation and
configuration:
All interface cables should be shielded, both inside and outside of the
CompactPCI enclosure. Braid/foil type shields are recommended for serial,
parallel, and SCSI interface cables. Where as external mouse cables are not
generally shielded, an internal mouse interface cable must either be shielded or
looped (1 turn) through a ferrite bead at the enclosure point of exit (bulkhead
connector). External cable connectors must be metal with metal back-shells and
provide 360-degree protection about the interface wires. The cable shield must be
terminated directly to the metal connector shell; shield ground drain wires alone
are not adequate. CompactPCI panel mount connectors that provide interface to
external cables (e.g.,
RS232, USB, keyboard, mouse, etc.) must have metal housings and provide
direct connection to the metal CompactPCI chassis. Connector ground drain
wires are not adequate.
