SERVICE MANUAL MANUEL D'ENTRETIEN WARTUNGSHANDBUCH CAUTION: Before servicing this chassis, it is important that the service technician read the "Safety Precautions" and "Product Safety Notices" in this service manual. ATTENTION: Avant d'effectuer l'entretien du chвassis, le technicien doit lire les «Prйcautions de sйcuritй» et les «Notices de sйcuritй du produit» prйsentйs dans le prйsent manuel. VORSICHT: Vor Цffnen des Gehдuses hat der Service-Ingenieur die ,,Sicherheitshinweise" und ,,Hinweise zur Produktsicherheit" in diesem Wartungshandbuch zu lesen. December 1999 ENGLISH SAFETY PRECAUTIONS WARNING: The following precautions must be observed. ALL PRODUCTS Before any service is performed on the chassis an isolation transformer should be inserted between the power line and the product. 1. When replacing the chassis in the cabinet, ensure all the protective devices are put back in place. 2. When service is required, observe the original lead dressing. Extra precaution should be taken to ensure correct lead dressing in any high voltage circuitry area. 3. Many electrical and mechanical parts in HITACHI products have special safety related characteristics. These characteristics are often not evident from visual inspection, nor can the protection afforded by them necessarily be obtained by using replacement components rated for higher voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified by marking with a ! on the schematics and the replacement parts list. The use of a substitute replacement component that does not have the same safety characteristics as the HITACHI recommended replacement one, shown in the parts list, may create electrical shock, fire, X-radiation, or other hazards. 4. Always replace original spacers and maintain lead lengths. Furthermore, where a short circuit has occurred, replace those components that indicate evidence of overheating. 5. Insulation resistance should not be less than 2M ohms at 500V DC between the main poles and any accessible metal parts. 6. No flashover or breakdown should occur during the dielectric strength test, applying 3kV AC or 4.25kV DC for two seconds between the main poles and accessible metal parts. 7. Before returning a serviced product to the customer, the service technician must thoroughly test the unit to be certain that it is completely safe to operate without danger of electrical shock. The service technician must make sure that no protective device built int
