Grounding the outer shields of the control cables at the cabinet entry

Ground the outer shields of all control cables 360 degrees at the EMI conductive cushions
as follows (example constructions are shown below, the actual hardware may vary):
1. Loosen the tightening screws of the EMI conductive cushions and pull the cushions
apart.
2. Cut adequate holes to the rubber grommets in the entry plate and put the cables through
the grommets and the cushions.
3. Strip off the cable plastic sheath above the entry plate just enough to ensure proper
connection of the bare shield and the EMI conductive cushions.
4. Tighten the two tightening screws so that the EMI conductive cushions press tightly
round the bare shield.
