    Safety instructions Contents of this chapter This chapter contains safety instructions which you must obey when you install and operate the converter, and do maintenance on the converter. If you ignore the safety instructions, injury, death or damage can occur to the converter, the generator or other adjoining equipment.
  • Page 6: Installation And Maintenance Work

    Installation and maintenance work These warnings are intended for all who work on the converter, generator cable or generator. WARNING! • Only qualified electricians are allowed to install and maintain the converter. • Before any installation work, the stator of the generator and the supply line input of the ACS800-67 must be isolated from the supply grid.
  • Page 7 • Do not make any insulation tests without disconnecting the converter from the cabling first. • When joining shipping splits (if any), check the cable connections at the joints before switching on the supply voltage. • Live parts on the inside of the doors are protected against direct contact. Pay special attention when handling metallic shrouds.
  • Page 8 WARNING! Ignoring the following instructions can cause physical injury or death, or damage to the equipment. • Use extreme caution when manoeuvring a converter or filter module that runs on wheels. The modules are heavy and have a high center of gravity. Make sure that the module does not topple over when you move it on the floor.
