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 electrical professional, do not do grounding work.
• Always ground the drive, the motor and adjoining equipment. This is necessary
for the personnel safety.
• Make sure that the conductivity of the protective earth (PE) conductors is
sufficient and that other requirements are met. See the electrical planning
instructions of the drive. Obey the applicable national and local regulations.
• When using shielded cables, make a 360° grounding of the cable shields at the
cable entries to reduce electromagnetic emission and interference.
• In a multiple-drive installation, connect each drive separately to the protective
earth (PE) busbar of the power supply.
