6.4 Cable cross-sections
The “Maximum terminal capacity” specification indicates the maximum
possible sizes that can be connected to the power terminals. The cross-
sectional areas and gauges that should be used for the power supply and
motor connections are recommendations for the corresponding frame sizes
and ratings and are provided as examples.

Use the general installation instructions and local conditions as a
basis when selecting terminal capacities.
