1 - Non-shielded power supply cable (2 or 3 phases to be connected to the Vario switch, and the PE
conductor to be connected to the ground terminal of the speed controller)
2 - Shielded motor cable (3 phases to be connected to the speed controller U-V-W terminals passing through
the ferrite core 7 (only ATV28EU••M2) , and the PE conductor which is to be connected to the earthing screw
on the heatsink 6 without passing through the ferrite core
3 - Control cable if used
4 - Cable for braking resistor (if used)
5 - Gland plate for customer cable glands. Glands should be of a type which does not reduce the IP rating
• Shielded cables must be used for connection to the control (if required) and connection to the braking
resistor (if required)
• The ferrite core 7, and clamps 8, 9 and 10 for grounding the shielding are provided with the speed
controller
• The optional connection to the relay contacts can be made using non-shielded cables
