Step 11: Ground The Unit - Proxim Tsunami 800 Series Hardware Installation Manual

: Use Outdoor-rated, UV protected, shielded Cat5e/Cat6 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 device 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.

Step 11: Ground the Unit

To ensure proper grounding, use either of the ground points which are situated at the bottom corners of the device and the
grounding screw(M24 thread size) provided to attach a ground wire of at least 12 AWG stranded to the device. It is important
that the following ground guidelines are followed during installations to protect the device against lighting or ESD events:
1. Connect one end of the grounding cable to the device and the other end to the closest earthing system point at the
installation.
2. Cut any extra ground wire length when finished connecting it to the single point earth ground.
3. Avoid sharp bends and never loop or coil up the ground wire, always connect it straight to ground.
4. A good earth ground impedance is less than 1.0 ohm.
5. Measure ground impedance at the point where the protector ground wire is connected and not at the ground rod.
6. Connect the surge protector ground wire and equipment ground (both power ground and telecomm ground) to a
single common ground.
7. Make sure all connections are fastened securely and are tight.
8. Never install during a storm and always follow your local safety codes.
