Removing the internal EMC filter

Figure 5-3 Removal and re-fitting of internal EMC filter

5.3.3

Further EMC precautions

Further EMC precautions are required if more stringent EMC emission requirements

apply:

Operation in the first environment of EN 61800-3

Conformity to the generic emission standards

Equipment which is sensitive to electrical interference operating nearby

In this case it is necessary to use:

The optional external EMC filter

A shielded motor cable, with screen clamped to the grounded metal panel

A shielded control cable, with screen clamped to the grounded metal panel

Full instructions are given in the IM-pAC Technical Data Guide.
A full range of external EMC filters is also available for use with IM-pAC.

The control circuits are isolated from the power circuits in the drive by basic insulation

(single insulation) only. The installer must ensure that the external control circuits are

insulated from human contact by at least one layer of insulation (supplementary

insulation) rated for use at the AC supply voltage.

WARNING

If the control circuits are to be connected to other circuits classified as Safety Extra Low

Voltage (SELV) (e.g. to personal computer), an additional isolating barrier must be

included in order to maintain the SELV classification.
