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 i

14、s imperative to verify that all exposed conductive surfaces are properly insulated from supply circuits. GMeter impedance should be equivalent to 1500 ohm shunted by 0.15F. “CAUTION” “F1, F2: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 10A, 125V FUSE.” CAUTION F1, F2:

15、REPLACE WITH SAME TYPE 10A, 125V FUSE. ATTENTION F1, F2: UTILISER UN FUSIBLE DE RECHANGE DE MEME TYPE DE 10A, 125V. GLeakage current must not exceed 0.5mA.

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 (t

18、in + silver + copper) Sn + Cu (tin + copper) Sn + Zn + Bi (tin + zinc + bismuth) Caution: 1. As the melting point temperature of the lead-free solder is about 30C to 40C (50F to 70F) higher than that of the lead solder, be sure to use a soldering iron suitable to each solder. 2. If lead solder must

19、be used, be sure to remove lead- free solder from each terminal section of the parts to be replaced and from the area around it completely before soldering, or make sure that the lead-free solder and lead solder melt together fully.
