MTU Instructions
General Installation and Wiring Guidelines
They must be secure and made in
accordance with the connection supplier’s
instructions. Generally, gel-filled
Insulation Displacement Connectors
(IDCs) such as 3M ScotchLok or AMP
Tel-Splice connectors should be used on
all wire-to-wire connections.
Splices located outdoors or in meter pits
should be further protected through the
use of a direct burial kit. This consists of
a gel-filled plastic tube that houses the
individual wire-to-wire splices to provide
additional protection from the elements.
MTU Positioning and
Mounting
General - MTUs must be positioned and
mounted properly to ensure optimum RF
signal propagation. Each MTU contains
an internal antenna near the top front
surface of the sealed enclosure. As a
result, the MTU should always be
mounted vertically and the STAR logo
should face the installer.
Since MTU transmissions are similar in
nature to cellular phone signals, a cellular
phone can be used to help to determine if
a location is suitable for MTU mounting.
If the cellular phone signal drops
dramatically or indicates no signal at the
desired location, it is possible that the
MTU signal will also be blocked at this
location. In this case, the MTU will have
to be mounted in a different location,
possibly on the outside of the structure.
Keep the MTU away from all other
electrical wires.
Note: Do not mount the MTU under
wiring such as Romex, AC power wires,
cable TV wire, or telephone wire. Do not
allow these wires to lay on top of, or in
front of the MTU.
Note: Keep the MTU six inches away
from metal items such as pipes, conduit,
electric meters, electrical boxes, and
downspouts.
Make sure screws used to mount the
MTU do not protrude and pierce or
otherwise damage any wires, cables, or
pipes.
Use of Spacer – There are two primary
styles of MTUs. The Original Flatpak
STAR MTU requires the use of a spacer
(Hexagram Part Number 056-5155H1)
when the MTU is mounted on any surface
other than wood. The NEW Flatpak
STAR MTU is a modified design that can
be directly mounted to a variety of
surfaces without the use of a spacer.
See the examples below for additional
information.
