Safety instructions7GroundingThese instructions are intended for all who are responsible for the grounding of thedrive.WARNING! Ignoring the following instructions can cause physical injury, death,increased electromagnetic interference and equipment malfunction:ï Ground the drive, motor and adjoining equipment to ensure personnel safety inall circumstances, and to reduce electromagnetic emission and pick-up.ï Make sure that grounding conductors are adequately sized as required bysafety regulations.ï In a multiple-drive installation, connect each drive separately to protectiveearth (PE).ï ACS800-01, ACS800-11: In European CE compliant installations and in otherinstallations where EMC emissions must be minimized, make a 360∞ highfrequency grounding of cable entries in order to suppress electromagneticdisturbances. In addition, connect the cable shields to protective earth (PE) inorder to meet safety regulations.ACS800-04 (45 to 560 kW) and ACS800-02 in first environment: make a 360∞high frequency grounding of motor cable entries at the cabinet lead-through.ï Do not install a drive with EMC filter option +E202 or +E200 (available forACS800-01 and ACS800-11 only) on an ungrounded power system or a high-resistance-grounded (over 30 ohms) power system.Note:ï Power cable shields are suitable for equipment grounding conductors onlywhen adequately sized to meet safety regulations.ï As the normal leakage current of the drive is higher than 3.5 mA AC or 10 mADC (stated by EN 50178, 5.2.11.1), a fixed protective earth connection isrequired.
