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 circuits. - Meter impedance should be equivalent to 1500 ohms shunted by 0.15 μF. ■ TO SERVICE PERSONNEL - Leakage current must not exceed 0.5mA. - Be sure to test for leakage with the AC plug in both polarities. WALL OUTLET EQUIPMENT UNDER TEST AC LEAKAGE TESTER OR EQUIVALENT INSULATING TABLE For U model CAUTION F1: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 5A, 125V FUSE. For C model CAUTION F1: REPLACE WITH SAME TYPE 5A, 125V FUSE. ATTENTION F1: UTILISER UN FUSIBLE DE RECHANGE DE MÉME TYPE DE 5A, 125V. All of the P.C.B.s installed in this unit and solder joints are soldered using the lead free solder. Among some types of lead free solder currently available, it is recommended to use one of the following types for the repair work. - Sn + Ag + Cu (tin + silver + copper) - Sn + Cu (tin + copper) - Sn + Zn + Bi (tin + zinc + bismuth) Caution: As the melting point temperature of the lead free solder is about 30°C to 40°C (50°F to 70°F) higher than\ that of the lead solder, be sure to use a soldering iron suitable to each solder.
