MTU Instructions
General Installation and Wiring Guidelines
Step 3 – Run wiring from the MTU to the
meter. Carefully staple the wire to the
wall every 18” and at every change in
direction using 9/16” staples. All turns
are to be at right angles. If wire must be
run on masonry, secure it with wire clips.
Run wires parallel to the joist. If a joist
must be crossed, run at a 90 degree
angle. If the MTU input cable must be
extended, use an appropriate splice.
Make sure inner conductors are not
nicked during stripping.
Step 4 – Make the appropriate
connections to the meter. Refer to the
specific MTU Instruction for the meter in
use.
Finished Basement
Step 1 – Select a mounting location for
the MTU that will allow optimum signal
transmission. In Finished basements,
this may be high on a ceiling joist in an
unfinished section of the basement or
high on an interior wall near a window or
outside wall, but at least a few inches
away from outside walls.
Note: Ceilings may contain metal.
Therefore, the MTU should be placed 2 to
3 inches down from a plaster or ‘dropped’
ceiling.
Step 2 – Mount the MTU.
• The MTU must be mounted
level, vertically with the STAR
logo facing the installer. Allow a
1” space between the top of the
MTU and any overhang above
it. This is critical for proper
radio signal transmission.
• Use a Spacer (Hexagram Part
Number 056-5155H1) if
mounting an Original Flatpak
STAR MTU on a non-wood
surface.
CAUTION!
Do not over tighten screws.
Excessive torque will crack
the MTU enclosure. Do not
tighten screws beyond the
point that the MTU touches
the mounting surface.
Step 3 - Run wiring from the MTU to the
meter. Run all wiring behind the wall if
possible. Carefully staple the wire to the
wall every 18” and at every change in
direction using 9/16” staples. All turns are
to be at right angles. If wire must be run
on masonry, secure it with wire clips. Run
wires parallel to the joist. If a joist must be
crossed, run at a 90 degree angle. If the
MTU input cable must be extended, use
an appropriate splice. Make sure inner
conductors are not nicked during
stripping.
Step 4 – Make the appropriate
connections to the meter. Refer to the
specific MTU Instruction for the meter in
use.
