prevent the customer from being exposed to shock hazards.LEAKAGE CURRENT COLD CHECK1. Unplug the AC cord and connect a jumper between the twoprongs on the plug.2. Measure the resistance value, with an ohm meter, between thejumpered AC plug and each exposed metallic cabinet part on theequipment such as screwheads, connectors, control shafts, etc.The resistance value must be more than 5M .Figure1LEAKAGE CURRENT HOT CHECK (See Figure 1)1. Plug the AC cord directly into the AC outlet. / Do not use anisolation transformer for this check.2. Connect a 1.5k , 10W resistor, in parallel with a 0.15 Fcapacitor, between each exposed metallic part on the set an agood earth ground such as a water pipe, as shown in Figure1.3. Use an AC voltmeter, with 1000 ohms/volt or more sensitivity, tomeasure the potential across the resistor.4. Check each exposed metallic part, and measure the voltage ateach point.5. Reverses the AC plug in the AC outlet repeat each of the abovemeasurements.6. The potential at any point should not exceed 0.15 volts RMS. Aleakage current tester (Simpson Model 229 equivalent) may beused to make the hot checks, leakage current must not exceed 0.1milliamp. In case a measurement is outside of the limits specified,3PDF created with pdfFactory Pro trial version www.pdffactory.com
