No Preview Available ! DCS800 Firmware manual DCS800 Drives (20 to 5200 A) 1 page 5 Grounding These instructions are intended for all who are responsible for the grounding of the drive. Incorrect grounding can cause physical injury, death and/or equipment malfunction and increase electromagnetic interference. WARNING! • Ground the drive, motor and adjoining equipment to ensure personnel safety in all circumstances, and to reduce electromagnetic emission and pick-up. • Make sure that grounding conductors are adequately sized and marked as required by safety regulations. • In a multiple-drive installation, connect each drive separately to protective earth (PE ). • Minimize EMC emission and make a 360° high frequency grounding (e.g. conductive sleeves) of screened cable entries at the cabinet lead-through plate. • Do not install a drive equipped with an EMC filter to an ungrounded power system or a high resistance-grounded (over 30 ohms) power system. Note: • Power cable shields are suitable as equipment grounding conductors only when adequately sized to meet safety regulations. • As the normal leakage current of the drive is higher than 3.5 mA AC or 10 mA DC (stated by EN 50178, 5.2.11.1), a fixed protective earth connection is required. 3ADW000193R0701 DCS800 Firmware Manual e g Safety instructions 5 Page 11
