Rotary Meter Cable

You may ship the Itron 2.4GZ OpenWay Remote Mount Gas Module directly to the meter
manufacturer fo r a fac tory -installed cable. If you connect the endpoint to the meter using an
existing cable purchased from the meter manufacturer, complete the following cable
installation procedure.

Caution The purchased cable must have a mating connector compatible to the
meter receptacle. Meter manufacturer's cables may be wired in different
configurations for specific applications. If necessary, contact your meter's
manufacturer for wiring diagrams for your specific application.

To connect the 2.4GZ OpenWay Remote Mount Gas Module to the rotary
meter cable

1. Remove the backplate (4 screws) from the 2.4GZ OpenWay Remote and expose the
module's lead wires. The backplate and screws will be re-installed on the gas module
later in this procedure so store them (temporar ily ) in a safe, secure place.

2. Insert the lead wires from the 2.4GZ OpenWay Remote Mount Gas Module into new
3M gel connectors (Itron part number CON-0023-001) together with the same colored
lead wire from the meter cable (see the wiring table below) and crimp using a 3M
hand-held crimping tool.

Note Do not strip lead wire prior to inserting the wire in the gel connector.

3. After completing the wiring connections, install a cable tie to the meter cable just
below the exposed colored lead wires on the cable insulation. Remove the excess
cable tie using a hand-held sidecutter pliers. The cable tie performs as a cable strain
relief to mitigate the risk of destructive tension on the lead wires.

4. Tuck the three gel connectors and cable tie inside the module housing, as shown.

5. Install the 2.4GZ OpenWay Remote Mount Gas Module backplate using the four
screws previously removed from the module and a Torx T-15 screwdriver. Install the
new 2.4GZ OpenWay Remote Mount Gas Module on the wall or a pipe using the
Remote Endpoint Mount Kit (Itron part number CFG-0005-003). See Mounting the

2.4GZ OpenWay Remote Mount Gas Module on page 9 for mounting instructions.

To connect the 2.4GZ OpenWay Remote Mount Gas Module cable assembly
to the rotary meter

Caution Verify the cable connector mates with the meter connector. Meter
manufacturers use different connector styles (types).

1. Align the large lug on the 2.4GZ OpenWay Remote Mount Gas Module connector
with the large notch on the meter connector.
