Grounding
These instructions are intended for all who are responsible for the
grounding of the drive. Incorrect grounding can cause physical injury,
death or equipment malfunction and increase electromagnetic interfer-
ence
• Ground the drive, motor and adjoining equipment to ensure per-
sonnel safety in all circumstances, and to reduce electromagnetic
emission and pick-up.
• Make sure that grounding conductors are adequately sized as re-
quired 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 ground-
ing of screened cable entries at the cabinet lead-through.
• Do not install a drive with EMC filter on an ungrounded power sys-
tem or a high resistance-grounded (over 30 ohms) power system.
Note:
• Power cable shields are suitable for equipment grounding conduc-
tors 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.
