Installation
1. Mount the station protector so as to minimize
the possibility of dirt or moisture getting into
the protector.
2. Station protectors mounted side-by-side or
end-to-end should be placed so covers can be
easily removed.
3. Where protection for multiple services is
required, it is recommended that a protected
building terminal in an interior terminal box be
installed in place of station protectors.
4. Mount the station protector vertically on a flat
surface utilizing the mounting holes shown in
Figure 2 and using the appropriate hardware
(the length of the mounting screws should
allow for 1/8” of length within the protector).
