• Connection cables between frequency converter and motor, if no corresponding output
filter is used.
• Connection cables filter and converter on the line side, where not directly flange
mounted
• It should be noted that the shielding effect of different cables can differ widely (foil shield,
braided shield with various degree of coverage, combinations).
6. Connect shielded cables on both sides and across a large-area with reference potential,
as far as possible directly or close to the input or output sides of the housing.
Use:
• EMC-compliant cable fittings (360° contact)
• An EMC baseplate
• Large-area contacting of the cable shield by suitable metal clips.
Avoid shielded terminals connected via top lines (pig tails)!
(Twisted shield braiding; soldered cable lugs etc.)
Ensure that an EMC-compliant cable gland is provided at the motor terminal box. It must
correspond to the degree of protection for its respective location of use. The motor terminal box
shall be made of metal, the connection between cable gland and terminal box must be of large-
area design. If the lacquer has been removed, it may be necessary to restore the corrosion-
protection layer.
