Installation Requirements Related to EN 61800-3 and the EMC Directive
- The drive must be earthed (grounded).
- Output power wiring to the motor must employ cable with a braided shield providing 75% or greater coverage, or the cables must be housed in metal conduit, or equivalent shielding must be provided. Continuous shielding must be provided from the drive enclosure to the motor enclosure. Both ends of the motor cable shield (or conduit) must terminate with a low-impedance connection to earth. At the drive end of the motor cable, terminate the shield at the PE Grounding Bar.
- At the motor end, the motor cable shield or conduit must terminate in a shielded connector which must be properly installed in an earthed motor wiring box that is attached to the motor. The motor-wiring box cover must be installed and earthed.
- All control (I/O) and signal wiring to the drive must use cable with a braided shield providing 75% or greater coverage, or the cables must be housed in metal conduit, or equivalent shielding must be provided. When shielded cable is used, the cable shield is terminated with a low-impedance connection to earth at only one end of the cable, preferably the end where the receiver is located. When the cable shield is terminated at the drive end, it can be terminated either by using a shielded connector with a conduit plate or conduit box, or the shield can be clamped to an ‘EMC plate.’
- Motor cables must be separated from control and signal wiring wherever possible.
- Maximum motor-cable length must not exceed the maximum length for compliance with radio-frequency emission limits for the specific standard and installation environment.
- The drive must be powered from an earthed supply system such as a TN or TT system and the PE-A and PE-B jumpers in the drive must be correctly configured.
- Verify that appropriate system design or filtering is used so that fault number 14118 ‘CapOvrResonance’ does not occur during standard operation.
