Figure 3-31 Surge Protector
: 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 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 9: Ground the Device
To ensure proper grounding, ground a wire of atleast 12 AWG stranded to the grounding screw (M3 thread size) which is
fixed to the bottom corner of the device. It is important to note that the following ground guidelines are followed during
installations:
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 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.
Connect the grounding wire, which is supplied with the product package, to the grounding lug as shown below:
