YST-SW5152YST-SW515WALLOUTLET EQUIPMENTUNDER TESTAC LEAKAGETESTER OREQUIVALENTINSULATINGTABLE TO SERVICE PERSONNEL1. Critical Components InformationComponents having special characteristics are marked sand must be replaced with parts having specifications equalto those originally installed.2. Leakage Current Measurement (For 120V Models Only)When service has been completed, it is imperative to verifythat all exposed conductive surfaces are properly insulatedfrom supply circuits. Meter impedance should be equivalent to 1500 ohm shuntedby 0.15μF.“CAUTION”“F1: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 6A, 125V FUSE.”CAUTIONF1: REPLACE WITH SAME TYPE 6A, 125V FUSE.ATTENTIONF1: UTILISER UN FUSIBLE DE RECHANGE DE MEME TYPE DE 6A, 125V. Leakage current must not exceed 0.5mA. Be sure to test for leakage with the AC plug in both polarities.WARNING: CHEMICAL CONTENT NOTICE!The solder used in the manufacturing process except soldering of the P.C.B. ass'y contains LEAD. In addition, otherelectrical/electronic and /or plastic (where applicable) components may also contain traces of chemicals found by theCalifornia Health and Welfare Agency (and possibly other entities) to cause cancer and/or birth defects or other reproductiveharm.DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REA-SON WHATSOEVER!Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or exposeeyes to solder/flux vapor!If you come in contact with solder or components located inside the enclosure of this product, wash your hands beforehandling food.All P.C.B.s used for this product are soldered with leadfree soldering material which is an alloy of Sn+Ag+Cu (tin+ silver + copper).Among some types of lead free solder currently available,it is recommended to use one of the following types for therepair work.• Sn + Ag + Cu (tin + silver + copper)• Sn + Cu (tin + copper)• Sn + Zn + Bi (tin + zinc + bismuth)1. As the melting point temperature of the lead free solderis about 30°C to 40°C (50°F to 70°F) higher than that ofthe lead solder, be sure to use a soldering iron suitableto each solder.2. If lead solder must be used, be sure to remove lead freesolder from each terminal section of the parts to bereplaced and from the area around it completely beforesoldering, or make sure that the lead free solder andlead solder melt together fully.About Lead Free Solder /www . xiaoyu163. comQQ 376315150 992894298TEL 13942296513 992894298051513673QQTEL 13942296513 QQ 376315150 892498299TEL 13942296513 QQ 376315150 892498299http://www.xiaoyu163.comhttp://www.xiaoyu163.com
