Grounding - ABB ACS800-U4 Hardware Manual

Grounding

These instructions are intended for all who are responsible for the grounding of the
drive.
WARNING! Ignoring the following instructions can cause physical injury, death,
increased electromagnetic interference and equipment malfunction:
•
Ground the drive, motor and adjoining equipment to ensure personnel safety in
all circumstances, and to reduce electromagnetic emission and interference.
•
Make sure that grounding conductors are adequately sized as required by
safety regulations.
•
In a multiple-drive installation, connect each drive separately to protective
earth (PE).
•
In first environment (EU EMC Directive): make a 360° high frequency
grounding of the motor cable entry at the cabinet lead-through.
•
Do not install a drive with EMC filter option +E202 or +E200 on an ungrounded
power system or a high resistance-grounded (over 30 ohms) power system.
Note:
•
Power cable shields are suitable for 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.
