4.1.2.4 Surge
Arrestors
T1
The T1 surge arrestor must be adequately grounded as outlined in the Quality
Standards Fixed Network Equipment - Installation Manual (R56). The surge
arrestor usually mounts near the demarcation (demarc) point. The cable
connecting the surge arrestor to the Telco SmartJack should be locally procured,
or should be provided with the surge arrestor. The cable connecting the iSC-3 to
the surge arrestor is locally procured.

GPS antennas
All antenna feed lines should terminate with a suitable surge arrestor within 12”
inside of the entry window. Each arrestor must connect to the master ground bar
located below the entry plate. It is recommended that the arrestors be mounted
to a mounting bracket to simplify grounding and cable installation.

AC power (optional)
An RFN customer-approved surge arrestor must be installed adjacent to the AC
power panel. Very short wire lengths between the arrestor and the power panel
are required for proper operation of equipment.

4.1.2.5 Grounding
Within the site, ground the main rack with a single dedicated connection between
the main rack and the master ground bar. The connecting wire must be a #2
AWG green-insulated copper wire.
the main rack and the master ground bar. The connecting wire must be a #2
AWG green-insulated copper wire.
Use appropriate lugs (and split ring lock washers when possible) with an anti-
oxidant grease applied for interior grounding connections and exterior secondary
grounding connections. If lock washers are used, they should be placed between
the nut and the lug to ensure the mechanical integrity of the connection. The
washer must not be secured between the lug and the surface to which it is
connected. Painted connections must be scraped clean before applying the anti-
oxidant grease and lug.
