Strip back the outer sheath then fold the braid back over the
sheath - you may have to partially or totally unravel it -
and place both the braid AND sheath together under the clamp.

If the cable also has a copper foil screen, rather than a
bonded aluminium one, tear it off so that it can't get in the
wrong place.

The clamp performs two function, one physical and one
electrical.
