There are no surge protectors over the center seizure screws and none should be installed. Adding surge
protectors degrades the return loss of the housing port.

To install coaxial cables in the base:
1
Loosen, but do not remove, the three bolts on top of the housing and the bolt on each side of the
housing. Rotate these bolts away from the cover.
2
Swing the housing lid away from the lower housing base.
3
Remove the protective port cap(s) in the base and verify that the seizure screw within either the
trunk or feeder port is loosened to accept the center pin of the cable connector.
4
Secure the cable end in the cable connector as described in the instruction sheet for the
connector.
5
Insert the center conductor fully until it enters the seizure mechanism. Tighten the terminal
screw onto the cable connector and torque to 12 in-lbs (1 ft-lb).
6
Repeat steps 3 through 5 for all other cable connections required.
7
Protect all cable connections with heat-shrink tape or tubing.
8
Lash the cables to the strand where they approach it and secure the cable lashing wire to the
strand with commercial clamps.
9
Verify that port plugs on any unused ports are firmly seated and torqued to 5 ft-lbs.

To install fiber cables in the lid:
Remove the protective port plug from the side of the housing lid and carefully pass the
1
connector ends of the fiber service cable through this port. It is necessary to insert one
connector at a time. Be careful not to bend the fiber any more than is necessary.
2
Thread the compression fitting into the port. The compression nut and rubber grommet must be
sufficiently loose to enable the fitting to be turned without turning the fiber cable at the same
time. Torque the main body of the fitting to 60 to 72 in-lbs (5 to 6 ft-lbs).
