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.
