> Hi David Drori A cover is no longer required (I'm not sure about Australia)
BABT application note 48, Issue 5, page 4 clause 8.1 A cover is only required if adaquate creepage and clearance cannot be maintained around the equipment, details of the clearance required and the line cord disconnection proceedure must be in the user guide. I recommend you obtain a copy of application note 48 from BABT 7 pages "Recommendations for Terminal Equipment for Use Inside A Host Equipment" BABT's telephone number is +44 1932 251200 BABT's Fax number is +44 1932 229756 Best regards Chris Penney - Freelance Dear Treggers, > >I have observed that data modem cards for the UK market, designed for >installation in PCs, have an insulating cover surrounding the TNV >(Telecommunications Network Voltage) areas of the circuit.
