Hard-
wire connections to either port from a compatible utility meter or Multi-
Read module is the same for each port. Note: the wiring is different when connecting a Schlumberger Proread (ARB-VI) encoder to a port. The MXU also requires proper programming of each port to match the device that is connected to the respective port. Refer to Invensys Pro-
gramming Manual AMR-988. I NSTALLATION
- W IRING I NSTRUCTIONS The MXU wiring instructions assume the utility meter with an encoder register or MultiRead module has been installed and the proper wire has been run to the MXU installation location. Three-conductor, 22 gauge, solid conductor cable is recommended. (For meter installation, refer to the installation information included in Invensys meter shipping cartons.) 1. Using the SR II security socket with ratchet wrench or nut driver, open the MXU enclosure by removing SR II type security screw. Bottom part of enclosure will contain the MXU battery and top part the electronics and connection wires. Connect the three wires from the encoder register or MultiRead module to the matching color wires on the MXU and the desired port. If not already done, strip of the encoder wire cable.

, and to green black black
, and red Note: For the Schlumberger Proread encoder, the color coded wire connections are not standard For Proread, connect the MXU red to Proread black, MXU green to Proread red, and MXU black to Proread green. Using gel-cap pliers, squeeze the gel-cap. This will splice the two wires and release the waterproof gel to seal the connection. The splice can be checked by pulling gently on the gel-cap while hold-
ing the wires to be sure they are tight and secure. Repeat Step 2 instructions for the remaining two wire connections. Repeat con-
nections to a second port, if required.
* If any of the wire connections are not being used they should be capped at the end with a gel-cap. This is to prevent water intrusion via wicking through the exposed wire ends. The red
, wires must be gel-capped individually. The green green TouchRead sensor wires can be gel-
capped together. black white striped

nected directly to an MXU port. The Proread register will not work through a MultiRead module connected to an MXU. 2. Connect the battery to the MXU electronics. Using the gel-cap con-
and wire and wire necting technique described in Step 2 above, connect the white stripe from the MXU electronics. Repeat the procedure for the white stripe from the MXU. red white stripe black white stripe wire from the battery to the wire from the battery to the black and and red Caution: DO NOT cross connect the black and white and red and white stripe wires of the MXU and battery pack as this may cause damage to the MXU electronics. connection, go to Step 3. If not, If using the optional TouchRead skip to Step 4. 3. (Optional) TouchRead Connection (available for Invensys register encoders only) The MXU includes a built-in TouchRead splitter connection to allow the encoder register to be interrogated by both RadioRead equipment and a remote TouchRead System sensor. 2 of 2 3. TouchPad Mounting (Optional) If mounting the MXU outdoors and a TouchRead TouchPad connection is to be included, mounting holes can be drilled in the side of the MXU bracket. Using short screws or plastic rivets, mount the TouchPad to the side of the MXU bracket. Caution: When using screws, be sure they do not penetrate the MXU enclosure when mounting the TouchPad. The TouchPad can also be mounted in a location away from the MXU. Be sure to use screws that are designed for and applicable to the mounting surface. For Pit Set Mounting:
1. Use 1/2 EMT. Select a location for the conduit where the MXUs installed position will not interfere with the meter and allow the MXU to be located as high as possible inside the meter box. The MXU should be kept approximately 1" from the sides of the meter box and positioned so the meter register odometer remains visible for visual conrmation readings. Conduit mounting method calls for driving a length of conduit into the ground at the bottom of the meter box. (If the bottom of the meter box does not have an open-
ing sufcient for driving the conduit vertically into the ground below, a different mounting method may need to be developed.) Place driver on conduit and strike with hammer, driving conduit down-
ward until it is at the desired height. The correct height should be at the point the driver is level with the top of the meter box in most cases. When completely installed, the top of the MXU should be about 1" below the meter box lid. 2. After installation of conduit, position the opening located in the bot-
tom of MXU over the conduit and press into place. Place meter box cover (lid) into position. Pit set installation is now complete. 3. TouchRead Sensor Mounting (Optional) If installing a TouchRead pit-set module follow the TR/PL mounting instructions on Invensys bulletin TR-997 for mounting in the meter box lid. Place meter box cover (lid) into position with the TR/PL sensor in place. FCC C OMPLIANCE NOTE:

AUTHORIZED INVENSYS DISTRIBUTOR Wall Mount TouchPad wire cable and gel-caps, connect wires to each of the white stripe wires from the MXU. Using two-conductor or three-conductor green and Note: If three-conductor wire cable is used, the third wire is not utilized for the TouchRead Connection. At the TouchPad connection, connect the same two wires to the terminal screws on the back of the TouchPad. Caution: Be sure there is no bare wire-to-wire contact. (The TouchRead connection is non-polarity sensitive and will work as long as the same color wires are used at both ends of the connection. If three-conductor wire is used, be sure the third dead wire is not mistakenly connected at either end.) Repeat the connections for a second port if required. red and black Pit-set Mount Sensor The TouchRead pit-set sensor includes a factory-sealed three-conductor wire cable. Proper wire connections are therefore important. To activate the pit-set TouchRead sensor, use only the wires from the sensor. Approximately 2"

Verify MXU operation prior to nal assembly: To verify RadioRead reading, use Radio Frequency Solid State Interrogator (RFSSI) or Vehicle Transceiver (VXU) to display the register odometer read-
ing(s), register ID number(s), and MXU ID number. (For AMR trou-
bleshooting, refer to bulletin AMR-309.)
-To verify TouchRead reading
, use a TouchRead visual reader to display register odometer reading(s) and register ID number(s). If MXU does not function, check all wire connections, re-do the connections or change battery pack. (For complete TouchRead installation and troubleshooting, see installation bulletins: TR-728, TR-997, and TR-998.) 5. After wiring connections are completed and MXU operation is veri-
ed, align guides of top and bottom parts of MXU and close, bring-
ing the connection wire(s) out the front side, using the wire pass-
thru guides located on either side of the security screw. Secure the top and bottom parts of the MXU using the security screw. Caution: DO NOT over-tighten security screw. OUNTING MXU M I NSTRUCTIONS For Wall Mounting: (Indoors and Outdoors) 1. Using MXU mounting bracket, nd a convenient location for the MXU mounting. It is recommended that the MXU be mounted in an upright position so the top part with the Invensys logo is facing up. The MXU mounting bracket can be mounted to a wall using screws or fastened to an object using heavy duty wire ties. Grooves have been placed in the back of the bracket for mounting on either hori-
zontal or vertical (existing) pipes. 2. After mounting MXU bracket, snap the MXU (which should already be wired as noted in the preceding wiring instructions) into the bracket. Be sure the locating tabs on either side of the MXU have snapped into position in the mounting bracket.The installation is now complete. Invensys Metering Systems P.O. Box 487 450 N.
