16 Safety
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 or
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).
• Where EMC emissions must be minimized, make a 360° high frequency
grounding of cable entries in order to suppress electromagnetic disturbances. In
addition, connect the cable shields to protective earth (PE) in order to meet safety
regulations.
Note:
• Power cable shields are suitable for equipment grounding conductors only when
adequately sized to meet safety regulations.
• Standard EN 61800-5-1 (section 4.3.5.5.2.) requires that 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 connection and:
- cross-section of the protective earthing conductor of at least 10 mm
2
Cu or
16 mm
2
Al, or
- automatic disconnection of the supply in case of discontinuity of the protective
earthing conductor, or
- a second protective earthing conductor of the same cross-sectional area as the
original protective earthing conductor.
