Grounding - ABB ACS800-17LC 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).
• Do not install a drive equipped with optional EMC filter +E202 to 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,
a fixed protective earth connection is required by EN 61800-5-1, 4.3.5.5.2. See
also Selecting the power cables, page 74.
