Electromagnetic Compatibility; Installation Diagram - Schneider Altivar 28 Manual De Usario

Wiring

Electromagnetic compatibility

Principle
• Grounds between speed controller, motor and cable shielding should have "high frequency"
equipotentiality
• Use shielded cables with shielding connected to ground at 360° at both ends for the motor cable,
braking resistor (if used) and control-command cables. Conduit or metal ducting can be used for part of
the shielding length, provided that there is no break in continuity
• Ensure maximum separation between the power supply cable (line supply) and the motor cable

Installation diagram

Assembling and connecting a shielded cable with metal clamp :
• Strip the shielding at one end of the cable
• Fold the shielding back over the external insulating sheath
• Feed the cable into the metal clamp and tighten the clamp around the shielding
