14.7 Surge Arrestor Wiring

An Andrew Grounding Kit and Surge Arrestor Unit must be located at the ODU and reliably

grounded as shown in Figure 95. There may also be a regulatory requirement to crossbond

the screened CAT-5 at regular intervals up the mast. Refer to local regulatory requirements

for further details.

A second Surge Arrestor Unit should be mounted at the building entry point and must be

grounded.

The termination of the CAT-5 Cable into the Surge Arrestor Unit is illustrated in Table 23,

Table 24 and Figure 119. The screen from the cable must be terminated into the ground

terminal within the unit to ensure the continuity of the screen. Earth Sleeving should be used

to cover the shield ground connection to prevent internal shorting within the unit.
