• 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 and the electrical
planning instructions of the drive.
To comply with standard IEC/EN 61800-5-1:
• use a protective earth conductor with a minimum cross-sectional area of 10 mm
2
Cu or 16 mm
2
Al (as an alternative when aluminum cables are permitted),
or
• use a second protective earth conductor of the same cross-sectional area as the
original protective earth conductor,
or
• use a device that automatically disconnects the supply if the protective earth
conductor is damaged.
If the protective earth conductor is separate (that is, it does not form part of the input
power cable or the input power cable enclosure), the minimum cross-sectional area
must be:
• 2.5 mm
2
when the conductor is mechanically protected,
or
• 4 mm
2
when the conductor is not mechanically protected.
