Arrestor Installation at Building Entry
This section describes installation of an arrestor at the building-entry end of the
ODU cable.
The building entry arr estor must be grounded to the master
gr ound bar at, or just below, the cable point of entry. For
details on master ground bar location, refer to the Best
Practices Guide.
The ULA is intended for bulkhead-mounted on the wall-feed-through plate, or within
the cable tray just inside the building.

Bulkhead Installation Procedure: Grounded Copper
Entryway Plate
The ULA ground wire is not required if the ULA is directly mounted to a properly
grounded copper entryway plate. This plate can either be a feed-through plate form-
ing the entryway itself, or a ground termination strip just inside the shelter entry-
way. The figure below illustrates the grounded entryway option.
