Trigno™ Wireless Biofeedback System- 30 -Appendix IMains IsolationThe Trigno Base Station is provided with Medical Grade isolated power supplywhich is compliant with IEC60601 series of harmonized standards for MedicalDevices. However, full compliance with IEC60601-1 Basic Safety for MedicalDevices requires that the PC operating the software be isolated as well. Thisstems from the basic requirement to have all patients electrically isolated fromequipment within their reach, and since the PC running the Trigno Software isconceivably within their reach, it too must be isolated.Delsys does not supply isolation transformers for PersonalComputers and their peripherals.Delsys recommends model IS1000HG manufactured by Tripp Lite(www.tripplite.com) for this task. This device is a medical gradeisolation transformer capable of delivering up to 1000 W. A smallersimilar version for 500W is also available (IS500HG). Similar productscompliant with IEC60601-1 are acceptable.
