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.

Note 1: Keep the shields continuous as close to the connection terminals as possible.
Secure the cables mechanically at the entry strain relief.
Note 2: If the outer surface of the shield is non-conductive:
