13、 1. Critical Components Information Components having special characteristics are marked s 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
14、 all exposed conductive surfaces are properly insulated from supply circuits. GMeter impedance should be equivalent to 1500 ohms shunted by 0.15F. GLeakage current must not exceed 0.5mA. GBe sure to test for leakage with the AC plug in both polarities. About Lead Free Solder / 無鉛 Side A Side B SMT R
