1 Safety Precautions1.1. General Guidelines1. When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have been overheated ordamaged by the short circuit.2. After servicing, see to it that all the protective devices such as insulation barriers, insulation papers shields are properlyinstalled.3. After servicing, make the following leakage current checks to prevent the customer from being exposed to shock hazards.4. When conducting repairs and servicing, do not attempt to modify the equipment, its parts or its materials.5. When wiring units (with cables, flexible cables or lead wires) are supplied as repair parts and only one wire or some of thewires have been broken or disconnected, do not attempt to repair or re-wire the units. Replace the entire wiring unit instead.6. When conducting repairs and servicing, do not twist the Fasten connectors but plug them straight in or unplug them straightout.1.1.1. Leakage Current Cold Check1. Unplug the AC cord and connect a jumper between thetwo prongs on the plug.2. Measure the resistance value, with an ohmmeter,between the jumpered AC plug and each exposedmetallic cabinet part on the equipment such asscrewheads, connectors, control shafts, etc. When theexposed metallic part has a return path to the chassis, thereading should be 100 Mohm and over.When the exposed metal does not have a return path tothe chassis, the reading must be .1.1.2. Leakage Current Hot Check (SeeFigure 1.)1. Plug the AC cord directly into the AC outlet. Do not usean isolation transformer for this check.2. Connect a 1.5kohm, 10 watts resistor, in parallel with a0.15μF capacitors, between each exposed metallic parton the set and a good earth ground such as a water pipe,as shown in Figure 1.3. Use an AC voltmeter, with 1000 ohms/volt or moresensitivity, to measure the potential across the resistor.4. Check each exposed metallic part, and measure thevoltage at each point.5. Reverse the AC plug in the AC outlet and repeat each ofthe above measurements.6. The potential at any point should not exceed 0.75 voltsRMS. A leakage current tester (Simpson Model 229 orequivalent) may be used to make the hot checks, leakagecurrent must not exceed 1/2 milliamp. In case ameasurement is outside of the limits specified, there is apossibility of a shock hazard, and the equipment shouldbe repaired and rechecked before it is returned to thecustomer.Figure 13
