40、ise purposes (i.e. exercise bike turning a fan or a wheel with friction belt).Over time, exercise machines added electronic and electric features, usually connected via cord and plugto the wall, and used the electricity to power the braking means, the user display, and other controls. Smallinternal

41、generators were also added to some exercise machines, in order to generate and provide internalpower to its own controls. For example exercise bikes that have no power cord and do not rely on externalpower, but generate their own power to supply the controls, display, brake, and onboard battery.With

42、 the continued push for green energy, further innovation and efficiency continued to take thistechnology further. Exercise machines are now being developed and put in use that harnesses the powerproduced by human effort/exercise, to not only power the exercise machine itself, but to capture theexces

43、s energy and make this available locally to power other loads within the building. This technology isbeing put in place on exercise bikes, stair climbers, elliptical machines, and other machines that generaterotational motion from user exertion, and converts this via a generator into electrical powe

44、r. This power isthen modified via an inverter, and made available to supplement grid connected branch circuit power.While the NEC and inverter systems safety requirements provide guidance and requirements for largerand more “permanent” power systems, these smaller, more portable, more “plug and play

45、” turnkeysystems are becoming more popular. Exercise machines are being marketed for connection via individualcord and plug into branch circuit outlets in homes, multiple machines connected via power strips, as wellSTANDARD NUMBER: UL 1647 -5-UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPROD
