MTU Instructions General Installation and Wiring Guidelines Intentionally Left Blank The FCC wants you to know….. This equipment has been tested and complies with Part 15 and Part 90 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference. This equipment generates, uses and can radiate radio frequency energy, and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
MTU Instructions General Installation and Wiring Guidelines Purpose & Scope This instruction outlines general practices and procedures for the installation and wiring of standalone, electronic interface Hexagram STAR MTUs. When installing an MTU, always refer to these instructions in addition to any specific instructions for the meter/MTU combination you will be installing and programming.
MTU Instructions General Installation and Wiring Guidelines Recommended Supplies We recommend the following supplies, for which quantities will depend upon the number of MTUs to be installed and the conditions encountered at each installation location. Item AMP Tel-Splice, 2-conductor Scotchlok, UR 2-3 wire gel-filled butt connector 3-conductor, 22 ga, solid wire, black UV jacket 3-conductor, 22 ga, solid wire, grey UV jacket AA alkaline battery, 1.
MTU Instructions General Installation and Wiring Guidelines Recommended Tools MTU Wiring • General - Many MTUs connect to the meter by means of a 3-conductor, 22gauge solid conductor wire. The wire is housed in a PVC jacket with UV inhibitors. A black-jacketed wire is supplied on single-port MTUs and for port 1 of dual-port MTUs. A grey jacket is used for the port two input to dual port MTUs.
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. 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.
MTU Instructions General Installation and Wiring Guidelines NEW Flatpak STAR MTU – An example of the NEW Flatpak STAR MTU is shown below. These MTUs are approximately 6.5” x 4.25” x 1.5” thick, and can be mounted on most surfaces without the use of a spacer. Original Flatpak STAR MTU – An example of an Original Flatpak STAR MTU is shown below. These MTUs are 6.5” x 5.5” X 1” thick, and require a spacer if mounted on any material other than wood.
MTU Instructions General Installation and Wiring Guidelines Outdoor Mounting MTUs mounted outdoors are typically mounted to the side of buildings, to a stationery post, to the piping surrounding the meter, or to a pit lid. Mounting to a Buiding or Post If the unit is being mounted to the outside of a building, the MTU will be connected to wires that lead from the inside to the outside of the building. If existing wire is used, it must be of the same quality as specified in MTU Wiring.
MTU Instructions General Installation and Wiring Guidelines Step 2 - Attach the spacer to the MTU using #10-32 stainless steel screws, nuts and washers. Tighten the screws to 12 to 15 in-lb. On a standard drill driver with 0 to 24 torque settings, this is typically the #10 setting. Pit-Lid Mounting For water or gas meters located in meter pits, MTUs can be mounted to the lower surface of the pit lid if an approved, nonmetallic pit lid is used.
MTU Instructions General Installation and Wiring Guidelines A long spacer is available, for use when the lower surface of the pit lid is a flat, solid surface. A short spacer is used when the lower surface of the pit lid in use has a ribbed construction. Do not mount the MTU if large metal objects, such as heating ducts, block both the front and rear of the MTU. If absolutely necessary, a single large metal object may be located several feet away from the MTU.
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.
MTU Instructions General Installation and Wiring Guidelines Do 9 Do check your cell phone for presence of a strong signal before entering a building or basement. Do install the MTU if the signal remains strong at the installation location. (Note: This is a guideline only. It does not guarantee that the MTU will be received by the DCU. However, if cell phone service is affected by the location, it is possible that the MTU transmission will also be blocked.
MTU Instructions General Installation and Wiring Guidelines Don’t 9 Don’t install the MTU if the cell phone signal was strong outside the building or basement and then goes into “no service” or a very weak signal at the MTU installation site. 9 Don’t select a location for MTU installation that is easy to install, but will not allow for good signal transmission. 9 Don’t select a location for MTU installation that is below grade.
