Figure 92: Lower Grounding Configuration

The Andrew Grounding Kit at the ODU is optional providing a Surge Arrestor Unit is located at
the ODU and is reliably grounded. However, it may be a regulatory requirement to cross-
bond the screened CAT-5 at regular intervals up the mast. Refer to local regulatory
requirements for further details.
The Canopy 150/300 PIDU 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 0.5m 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 13,
Table 14 and Figure 92 . The screen from the cable must be terminated into the ground
terminal within the unit to ensure the continuity of the screen. Ground (Earth) Sleeving should
be used to cover the shield ground connection to prevent internal shorting within the unit.
