    Safety vacon • 5 AFETY This manual contains warnings and cautions, which are identified with safety symbols. The warnings and cautions give important information on how to prevent injury and damage to the equipment or your system. Read the warnings and cautions carefully and obey their instructions.

  • Page 8: Warnings

    • 6 Safety Warnings Do not touch the components of the power unit, LCL filter or pre-charging circuit when the drive is connected to Mains, or the DC-link when DC-link is powered. The compo- nents are live when the drive is connected to mains or the DC-link is powered. A con- tact with this voltage is very dangerous.
