Wire rope for safety tether
1. Choose a location (on the B-end of the railcar) for the CMU bracket that orients the CMU lid
toward the sky to promote good Global Navigation Satellite System performance. Ensure there
is a tie off point for the safety tether. Ensure mounting surface is free of imperfections that may
prevent the magnets from mounting flush and securing to the asset’s mounting surface.
2. Thread the wire rope through the ferrule and around one of the bracket feet, and back
through the ferrule as shown on next page. Make the wire loop taut around the bracket foot so
the safety tether cannot be removed over the magnet. Use electrician pliers to crimp the ferrule.
Various electrician pliers are acceptable.
3 Take caution that the tether does not cause a tripping hazard or get tangled in other
equipment.
4. If the entire length of wire rope is not needed, pull the excess wire through the second ferrule,
crimp, and cut off any excess wire rope.
5. Fasten CMU to bracket using 4 machine screws provided. Torque screws to 5.1-5.6 Nm [45-
50 In-lbs].
6. Upon completion of all optional WSN sensors and the CMU mounting, place a magnet on top
of the CMU at the magnet indentation for 20 seconds to force a cellular call from the CMU. The
magnet from the red label may be reused for this.
