The warnings and cautions give important information on how to prevent injury and damage to the equipment or your system.

  • Page 9: Danger

    Safety vacon • 7 Danger Do not touch the components of the power unit when the drive is connected to mains. The components are live when the drive is connected to mains. A contact with this voltage is very dangerous.

  • Page 10: Grounding And Earth Fault Protection

    • 8 Safety Do not make measurements when the AC drive is connected to mains. It can cause damage to the drive. Make sure that there is reinforced protective ground connection. It is mandatory, because the touch current of the AC drives is more than 3.5 mA AC (refer to EN 61800-5-1).
  • Page 11 Safety vacon • 9 a) The protective grounding conductor must have a cross-sectional area of minimum 10 mm Cu or 16 mm Al. OR b) There must be an automatic disconnection of the mains, if the protective grounding conductor breaks. See Chapter 6. OR c) There must be a terminal for a second protective grounding conductor in the same cross- sectional area as the first protective grounding conductor.
