Motorola PTP 400 Series - Manual (Page 150)

148
The PTP 400 Series Bridge PIDU Plus to ODU cable requires Surge Arrestor Units mounted
at both ends of the cable. At the ODU, the Surge Arrestor Unit should be mounted within
0.3m (1 foot) of the ODU and must be grounded to the ODU. For mast installations, the Surge
Arrestor Unit should be mounted at the same height as the ODU.
The lower 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 16,
Table 17 and Figure 81. 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.
