Remove the outer insulation of the
interconnection cable (65mm/2.5"")

•

Split the silver plated copper braid into two
parts. Leave about 15mm/1.6" of the braid.

•

Twist one part of the braid to a wire.

•

Cut the other part.

•

Flip the remaining part of the braid over the
outer insulation of the interconnection wire.

•

Remove the conductive aluminium tape
around the cable bundle. Leave about
15mm/1.6" of the tape.
