3 Typical Mounting of Outdoor RTU General All remote panel boxes should be mounted securely to eliminate excessive vibration. Outdoor installation can be done by mounting the rainproof enclosure to (2) four-inch by four inch treated posts or corrosion resistant supports using mounting-strut channel and brackets as shown. The remote unit should be located as close as possible to the water tower ladder or pole where the antenna is mounted. All ¾ or 1 rigid power and transducer conduit connections to the enclosure shall be located in the lower right hand corner of the panel, and antenna coax conduit connections shall be located in the lower left hand corner of the panel. This will insure space is available for the RTU battery. All wires in and out of the RTU must be in ¾ or 1 rigid conduit. The only exception will be the ground wire as shown. The ground wire can exit the box via a drilled hole in the rear left corner of the panel. Typical conduit runs will be to electrical service, meter pit or vault for the transducer, and the antenna. The antenna conduit vertical run must be at least 15 feet up to a weatherhead. NO CONDUIT CONNECTIONS SHALL BE MADE IN THE TOP OF THE ENCLOSURE. Grounding for the RTU is accomplished by driving an 8/10-ft copper clad ground rod as close to the remote as possible. Using #8 or #10 solid copper wire, attach the ground rod to the coax lightning arrestor on the interior panel as depicted below. Any holes in the exterior enclosure MUST be sealed with silicone to keep the insects out. WEATHER HEAD GALVANIZED CHANNEL STRUT BRACKETS CCA TREATED 4"X4"X8' POSTS.

8 Antenna Installation General The antenna is a very critical link in radio telemetry. Correct installation is a MUST for proper radio communications. The installer/contractor of the equipment must follow the requirements set by Micro-Comm. If these requirements are not met, then the Installer/Contractor must redo the installation at their expense. The minimum antenna height shall be fifty feet (50 ft), for standpipes, ground storage, and elevated tanks. Central terminal units located at plants and offices, shall have a minimum height of forty-five feet (45 ft). All other remotes shall have a minimum antenna height of twenty feet (20 ft). Use these heights unless otherwise specified. Micro-Comm supplies mounting brackets, U-bolts, coax, connectors, and tape for proper installation. Attaching the coax connector is very critical, requiring the installer to contact Micro-Comm for proper connection instructions. A typical procedure that works well at Micro-Comm is for the installer to complete the remote installation, with the exception of the antenna and coax. During start-up of the remote, Micro- Comm will attach the coax to the antenna (including proper taping), then allow the installer to finish mounting the antenna. The installer may make antenna connections if previous arrangements have been made with Micro-Comm. Antenna polarization (vertical or horizontal) will be specified on a job-by-job basis (if it is not specifically stated, use horizontal polarization). Specific information on installation is covered on pages 19, 20,21 of this manual.

All other points have six layers of electrical tape (all tape is provided by Micro-Comm). Coax should be taped every 3' to the mounting structure. 8

12 PL259 Connector Installation Drawing 1) Strip coax back as shown below, be careful to not scar center conductor. 1/2" 1/2" 2) Slide the threaded connector cover onto coax. 3) Screw the PL259 connector onto the coax until snug. Use pliers if necessary to make sure the PL259 is completely seated. Once the connecter is in place, use an ohm meter to check and make sure that no short exists between the center pin and the outer conductor then solder all four holes and the center conductor. 4) Once the connector has cooled, again use an ohm meter to check and make sure that no short exists between the center pin and the outer conductor. Once the connector cools, screw the connector cover into place 12

13 Antenna Type N Connector Installation Drawing 1) Strip coax back as shown below, be careful to not scar center conductor. 1/4" 1/2" 2) Screw type N connector onto coax until snug. Pliers can be used to tighten the connector but be sure that the center pin is not pushed out from over tightening the connector. Center pin will push out and cause the connector not to work if over tightened. 3) Check to see that the center conductor is past the small hole in the center pin, and make sure the shield is visible in the two holes in the side of the Type N connector. Then, without getting things too hot, solder the center pin and the two holes in the side. 4) Once the connector has cooled, use an ohm meter to check and make sure that no short exists between the center pin and the outer conductor. Then screw the out side piece onto the type N connector. This piece contains an o-ring that will melt if the connector is screwed on before the connector has cooled. O-ring wiil melt if screwed onto connector before connector has cooled 13

14 Mounting the Transducer Typical Outdoor Installation for Water Towers and Pressure Stations The transducer must be located between the water tank and any altitude/control valve. The transducer must be able to sense the static pressure of the water. The transducer tap should be at least 45 degrees off the top center of the water main. A 3/4-inch corp. stop is typically used to tap the main, which is followed by a 3/4 inch to 1/4-inch female brass bushing. Micro-Comm will supply a 1/4-inch male polyflow fitting. The transducer is connected to the fitting using 6-10 of poly tubing. The transducer tubing must be bled of air before final connection. Do not rest the transducer on any metal pipe surface in the meter pit. The pre-cabled transducer shall be located in an underground meter service vault, which is connected via 3/4-inch rigid conduit to the telemetry remote panel. NOTE: Transducer MUST be below the FROST LINE and air space should be packed with insulation (inside a trash bag) to prevent freezing.
