To mount the lightning protection at the building entry point:
1. Mount the device outside the building, located as near as possible to the
entrance of the CAT-5e ODU-IDU cable. Mount the unit so that the cable
connectors are at the bottom (to prevent water from penetrating), with
the strain reliefs facing the ground.
2. Remove the cover by unscrewing the front of the unit.
3. Mount the unit to an outside surface using the two mounting holes.
4. Connect the ODU-IDU cable using the RJ-45 jack.
5. Connect one cable between the IDU and the suppressor using an RJ-45
jack.
6. Connect the suppressor’s ground stud to a grounding point. Use the
appropriate wire gauge and type, keeping the wire as short as possible,
less than 1m (3’), between the stud and the site grounding point.
7. Replace the cover
Note
There may also be regulatory requirements to cross bond the ODU-IDU CAT-
5e cable at regular intervals up the mast. This may be as frequent as every
10 meters (33 feet).
