Appendix I
Mains Isolation
The Trigno Base Station is provided with Medical Grade isolated power supply
which is compliant with IEC60601 series of harmonized standards for Medical
Devices. However, full compliance with IEC60601-1 Basic Safety for Medical
Devices requires that the PC operating the software be isolated as well. This
stems from the basic requirement to have all patients electrically isolated from
equipment within their reach, and since the PC running the Trigno Software is
conceivably within their reach, it too must be isolated.
Delsys does not supply isolation transformers for Personal
Computers and their peripherals.
Delsys recommends model IS1000HG manufactured by Tripp Lite
(www.tripplite.com) for this task. This device is a medial grade
isolation transformer capable of delivering up to 1000 W. A smaller
similar version for 500W is also available (IS500HG). Similar products
compliant with IEC60601-1 are acceptable.
