Installation

1. The TII 312 Series is a Station Protector which
consists of a DRM Series Surge Protector
Module in a 312 Protector Enclosure with a
molded in ground stud.

grommet located in the center of the base lip
to allow Telco cable, customer cable and
grounding conductor penetration. It is
equipped with a universal grounding and
mounting tab. (See Figure 1).

3. The TII DRM Series Station Protector Module
utilizes gel-sealed screw drive IDC input
connections & tool-less output IDC rockers.
They are also equipped with integral sealed
test points for ease of troubleshooting.

4. All ports accept .4mm to 1.5mm awg wire.

5. The TII DRM Series Station Protector Modules
are equipped with removable 5 pin protector
modules and are available in non-protected
and protected versions.

Features

Figure 1

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).

8. Fully insert the output wires into wire their
respective tip and ring (color-coded) ports at
the same time until they bottom out.

9. While holding wires in the wire guides,
terminate rocker by lowering rocker all the
way.

10. Assure the rocker is in the down position (See
Figure 3). Pull on wires to ensure proper

connection. Wires should remain securely
