SHIELD*
If no dedicated "shield" connector
is provided, ground the inner cable
shields to the chassis.
At the other end of the cable, leave
the shield unconnected, or connect
it to ground via a capacitor with a
value of a few nanofarads.
Where grounding clamps are not
available, twist the shield strands
into a bundle, crimp a lug terminal
onto it and fasten the lug to the
chassis. Secure the cable into
place with eg. cable ties.
