360 degrees EMC grounding at the cable entry
1. Loosen the fastening screws of the EMI conductive cushions and pull the
cushions apart.
2. Cut adequate holes to the rubber grommets in the lead-through plate and lead the
cables through the grommets and the cushions into the cabinet.
3. Strip off the cable plastic sheath above the lead-through plate just enough to
ensure proper connection of the bare shield and the EMI conductive cushions.
4. Tighten the two fastening screws (1) so that the EMI conductive cushions press
tightly round the bare shield.
Note: If the outer surface of the shield is non-conductive:
•Cut the shield at the midpoint of the bare part. Be careful not to cut the
conductors or the grounding wire (if present).
•Turn the shield inside out to expose its conductive surface.
•Cover the turned shield and the stripped cable with copper foil to keep the
shielding continuous.
