LEAKAGE CURRENT CHECK Measure leakage current to a known earth ground (water pipe, conduit, etc.) by connecting a leakage current tester such as Simpson Model

17、229-2 or equivalent between the earth ground and all exposed metal parts of the appliance (input/output terminals, screwheads, metal overlays, control shaft, etc.). Plug the AC line cord of the appliance directly into a 120V AC 60Hz outlet and turn the AC power switch on. Any current measured must n

18、ot exceed 0.5mA. (FOR USA MODEL ONLY) Leakage current tester Reading should not be above 0.5mA Device under test Test all exposed metal surfaces Also test with plug reversed (Using AC adapter plug as required) Earth ground AC Leakage Test VSX-49TX, VSX-47TX 3 2.1 PACKING 1Power CordADG7052 2FM Wire
