Ground Connections - ABB ACS550 User Manual

266
Size wiring according to local safety regulations, appropriate input voltage and the
drive's load current. In any case, the conductor must be less than the maximum limit
defined by the terminal size (see section
268).
The table below lists copper and aluminium cable types for different load currents.
These recommendations apply only for the conditions listed at the top of the table.
Based on:
• EN 60204-1 and IEC 60364-5-2/2001
• PVC insulation
• 30 °C (86 °F) ambient temperature
• 70 °C (158 °F) surface temperature
• cables with concentric copper shield
• not more than nine cables laid on cable ladder
side by side.

Ground connections

For personnel safety, proper operation and reduction of electromagnetic emission/
pick-up, the drive and the motor must be grounded at the installation site.
• Conductors must be adequately sized as required by safety regulations.
• Power cable shields must be connected to the drive PE terminal in order to meet
safety regulations.
