Viglen, EMC and the ‘CE’ mark
CE Marking
European standards are being harmonised across borders. If products comply with the same
standards in all European countries, product exporting and importing is made simple - paving our way
to a common market. If you buy a product with a 'CE' mark on it (shown below), on the box, in the
manual, or on the guarantee - it complies with the currently enforced directive(s).
Introduction to EMC
EMC (Electromagnetic Compatibility) is the term used to describe certain issues with RF (Radio
Frequency) energy. Electrical items should be designed so they do not interfere with each other
through RF emissions. E.g. If you turn on your microwave, your television shouldn't display
interference if both items are CE marked to the EMC directive.
If emitted RF energy is not kept low, it can interfere with other electrical circuitry - E.g. Cars Automatic
Braking Systems have been known to activate by themselves while in a strong RF field. As this has
obvious repercussions ALL electrical products likely to cause RF related problems have to be 'CE'
marked from 1st January 1996 onwards.
If a product conforms to the EMC directive, not only should its RF emissions be very low, but its
immunity to RF energy (and other types) should be high. The apparatus has to resist many 'real
world' phenomena such as static shocks and mains voltage transients.
Viglen’s Environment laboratory
To gain a 'CE' mark, the Viglen computer range has had to undergo many difficult tests to ensure it is
Electromagnetically Compatible. These are carried out in the in-house 'Environment lab' at Viglen
Headquarters. We have made every effort to guarantee that each computer leaving our factory
complies fully with the correct standards. To ensure the computer system maintains compliance
throughout its functional life, it is essential you follow these guidelines.
¾
Install the system according to Viglen’s instructions
¾
If you open up your Viglen:
¾
Keep internal cabling in place as supplied.
¾
Ensure the lid is tightly secured afterwards
¾
Do not remove drive bay shields unless installing a 'CE' marked peripheral in its place
¾
The clips or ‘bumps' around the lips of the case increase conductivity - do not remove or
damage.
¾
Do not remove the ferrite ring from the L.E.D cables.
¾
Only use your Viglen computer with 'CE' marked peripherals
This system has been tested in accordance with European standards for use in residential and light
industrial areas-this specifies a 10 meter testing radius for emissions and immunity. If you do
experience any adverse affects which you think might be related to your computer, try moving it at
least 10 meters away from the affected item. If you still experience problems, contact Viglen’s
Technical Support department who will put you straight through to an EMC engineer - s/he will do
everything possible to help. If modifications are made to your Viglen computer system, it might breach
EMC regulations. Viglen take no responsibility (with regards to EMC characteristics) of equipment
which has been tampered with or modified.
