*If no dedicated “shield” connector
is provided, ground the inner cable
shields to the chassis.
SHIELD*
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. 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.
