Installation (Precautions)
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 using appropriate hardware (the
length of the mounting screws should allow for
1/8” of length within the protector.
5. The mounting holes are covered with a thin
film of plastic, easily punched out, to maintain
the environmental integrity of the protector
(See Figure 2).
