Step 8: Install Surge Protector
Proxim recommends two approved lightning surge protectors to be installed, one near to the device and the other at the
building ingress point.
: To buy a suitable Surge Protector, place an order separately with your distributor.
Perform the following steps to ensure proper surge protection:
1. Mount the surge protector near the outdoor device and use 10 AWG or larger wire to connect the protector's ground
lug to the appropriate mounting ground point. The outdoor device and co-located surge protector should have a
common grounding point using the shortest possible grounding cable.
2. Mount a second surge protector near the building ingress and use 10 AWG or larger wire to connect the surge
protector's ground lug to earth ground as shown in the following figure.
: Use Outdoor-rated, UV protected, shielded Cat5/Cat5e or better cable for the following:
3. Connect an RJ45 terminated cable between the indoor device and to the port on the surge protector at the building
ingress.
4. Connect a short RJ45 terminated cable between the outdoor equipment and the port on the co-located surge
protector.
5. Connect an RJ45 terminated cable between the two surge protectors on their remaining ports.
: Ensure to loop the cable before entering the premise to prevent water ingress.
