Critical Components Information Components having special characteris

12、tics are marked Z and must be replaced with parts having specifications equal to those originally installed. 2. Leakage Current Measurement (For 120V Models Only) When service has been completed, it is imperative to verify that all exposed conductive surfaces are properly insulated from supply circu

13、its. GMeter impedance should be equivalent to 1500 ohms shunted by 0.15F. AC LEAKAGE TESTER OR EQUIVALENT EQUIPMENT UNDER TEST INSULATING TABLE WALL OUTLET GLeakage current must not exceed 0.5mA. GBe sure to test for leakage with the AC plug in both polarities. WARNING: CHEMICAL CONTENT NOTICE! The
