MTU Single Port Pulse Devices Installation Instructions
Wire Protection
A drip loop below the MTU is not required.
Inspect wire to ensure that routing and stapling have not caused wire damage. Pull the wire lightly at
each staple to make sure that the staple is not set too tightly.
Any splices made to wire must be suitable for the environment and made in accordance with national
and local codes, as well as the connection supplier’s instructions. Generally, gel-filled Insulation
Displacement Connectors (IDCs) such as 3M ScotchLok or AMP TelSplice connectors should be used
on all wire-to-wire connections.
Figure 1.1 Insulation Displacement Connectors
Splices located outdoors or in meter pits should be further protected through the use of a direct burial
kit. This consists of gel-filled plastic enclosures that house the individual wire-to-wire splices and
provide additional protection from the elements.

Run wiring from the MTU to the meter.
• All wiring should be behind the wall, if possible. Otherwise, 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 ceiling joist. If a joist must be crossed, do so at a 90 degree angle.
