Printed circuit boards
WARNING!
Use a grounding wrist band when you handle printed circuit boards. Do not touch
the boards unnecessarily. The boards contain components sensitive to electrostatic
discharge.

Grounding
These instructions are for all personnel who are responsible for the grounding of the drive.
WARNING!
Obey these instructions. If you ignore them, injury or death, or equipment
malfunction can occur, and electromagnetic interference can increase.
If you are not a qualified electrician, do not do grounding work.
•
Always ground the drive, the motor and adjoining equipment. This is necessary for the
personnel safety. Proper grounding also reduces electromagnetic emission and
interference.
•
Make sure that the conductivity of the protective earth (PE) conductors is sufficient. See
the electrical planning instructions of the drive. Obey the local regulations.
•
Connect the power cable shields to protective earth (PE) terminals of the drive to make
sure of personnel safety.
•
Make a 360° grounding of the power and control cable shields at the cable entries to
suppress electromagnetic disturbances.
•
In a multiple-drive installation, connect each drive separately to the protective earth
(PE) busbar of the power supply.
Note:
•
You can use power cable shields as grounding conductors only when their conductivity
is sufficient.
•
As the normal touch current of the drive is higher than 3.5 mA AC or 10 mA DC, you
must use a fixed protective earth (PE) connection. The minimum size of the protective
earth conductor must comply with the local safety regulations for high protective earth
conductor current equipment. See standard IEC/EN 61800-5-1, 4.3.5.5.2., and the
electrical planning instructions of the drive.
