have been overheated or damaged by the short circuit. After servicing, see to it that all the protective
devices such as insulation barriers, insulation papers shields are properly installed. After servicing,
make the following leakage current checks to prevent the customer from being exposed to shock
hazards.
1) Leakage Current Cold Check
2) Leakage Current Hot Check
3) Prevention of Electro Static Discharge (ESD) to Electrostatic Sensitive
4
1-2. Insurance notice
1. Check if there is any leak of current.
2. Cut out the power supply before the repair to avoid an electrical shock hazard.
3. In the case of a live-line test, insulating gloves should be worn to avoid potential electrical shock.
4. Confirm the rated current, voltage and capacity before testing with any kinds of instruments.
5. Watch if the upper door is open when you check something at a lower position.
6. Take out every part in the cabinet before moving the machine, especially things like panels (e.g. glass
