SG4000 Installation and Operation Manual
For aerial metal-strand connections, the strand clamp is usually sufficient. However, an
additional 5/16-inch bolt is included. Attach a wire from earth ground to this bolt and tighten
securely into one of the pedestal mounting holes on the rear of the housing base.
For pedestal installations, attach a ground wire to the extra 5/16-inch bolt and screw it into one
of the strand clamp holes.
Coaxial Cable Installation
Connections to the housing are made using standard KS-type housing port entry connectors.
Pin-type connectors with a nominal center conductor diameter of 0.067 inches are required.
Measuring from the seating plane of the connector, the center conductor pin length must be
1.50 inches minimum and 1.65 inches maximum.
Figure 5-10 illustrates the dimensions of the center conductor.

The SG4000 port entry seizure mechanism contains a 1/16-inch hex-head screw that travels
within a threaded ferrule to secure the connector. This screw is captive and should not be
backed out by using excessive force.
To install coaxial cables in the base:
1 Remove the protective port cap(s) in the base and carefully loosen the seizure screw to
accept the center pin of the cable connector.
2 Secure the cable end in the cable connector, as described in the instruction sheet for the
connector.
3 Insert the center conductor fully until it enters the seizure mechanism.
4 Tighten the seizure terminal screw onto the cable connector and torque to 12 in-lbs (1 ft-lb).
5 Repeat steps 1 through 4 for all other cable connections required.
6 Protect all cable connections with heat-shrink tape or tubing.
7 Lash the cables to the strand where they approach it and secure the cable lashing wire to
the strand with commercial clamps.
8 Verify that port plugs on any unused ports are firmly seated and torqued to 5 ft-lbs.
