2.1 GENERAL GUIDELINES
TOP PREVIOUS NEXT
1. When servicing, observe the original lead dress. If a short circuit is found, replace all parts which
have been overheated or damaged by the short circuit.
2. After servicing, see to it that all the protective devices such as insulation barriers, insulation
papers shields are properly installed.
3. After servicing, make the following leakage current checks to prevent the customer from being
exposed to shock hazards.
2.1.1 LEAKAGE CURRENT COLD CHECK
2.1.2 LEAKAGE CURRENT HOT CHECK (See Figure 1 .)

2.1.1 LEAKAGE CURRENT COLD CHECK
TOP PREVIOUS NEXT
1. Unplug the AC cord and connect a jumper between the two prongs on the plug.
2. Measure the resistance value, with an ohmmeter, between the jumpered AC plug and each
exposed metallic cabinet part on the equipment such as screwheads, connectors, control shafts,
etc. When the exposed metallic part has a return path to thechassis,the reading should be between
1MΩand 5.2MΩ.
When the exposed metal does not have a return path to the chassis, the reading must be
.
