1. The ALPU SERIES is intended to be installed indoors or outdoors, on wall or pole
mount applications. The unit features mounting feet on the sides that mount on 4” center-
to-center holes with #10 sized hardware. The mount foot also adapts to 4” diameter pole
mounting kits with a 4.5” center-to-center holes and larger hardware. Refer to Figure 1
for mechanical requirements and connector locations. The optimum ground connection on
the metal enclosure unit at the mounting flange on either side is shown in Figure 2. Use
minimum 8AWG wire for a ground reference attachment. Communication cables with the
RJ45 connectors already installed can feed directly into the enclosure. Be sure to install the
cables with the unprotected cable installed into the left “in” jack and the protected equipment
cable in the right “out” jack. The enclosure features a built in cable retention that grips the
cable with a screw down bracket.
A pole mount adapter kit (pn 1000-1164) is available to meet installations on a wide range of
pole diameters from 2” metal fence poles to 10” diameter utility poles.
