2. Remove 1.6 in. of cable sheath at the RS485-Power

Injector end of the RS485 communication cable.

3. Shorten the shield to 0.6 in.

4. Pull back the shield and cover with conductive

adhesive foil. This is where the shield clamp will be

attached later.

insulated conductor not required down to the cable sleeve.
