Grounding - ABB DCS880 series Hardware Manual

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 (> 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
-
(stated by EN 50178, 5.2.11.1), a fixed protective earth connection is required.
