Connecting the 2.4GZ OpenWay Remote Mount Module to the
Rotary Meter Cable
You may ship the Itron 2.4GZ OpenWay Remote Mount Gas Module directly to the meter
manufacturer for a factory-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 (temporarily) 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.

2. Align the lock ring notches on the module cable connector with the pins on the meter
connector.
3. Hold the lock ring on the module connector back and push the plug into the meter
connector until it is securely seated.
4. Turn the lock ring clockwise as far as it will go. You will feel it snap into place when
it locks.
Warning To remove the module connector plug from the meter connector jack,
push in on the lock ring, turn the lock ring counterclockwise as far as possible,
and pull out the plug body. Do not pull on the module's connector cable.

Rotary Meter Installation
Installing the 2.4GZ OpenWay Remote Mount Gas Module to
the Elster American Meter RPM Series Rotary Meter
Some meter manufacturers provide endpoint mounting kits and installation procedures for
their meters.
If 2.4GZ OpenWay Remote Mount Gas Module to Elster American RPM meter installation
instructions are not available, follow the installation procedure in this section.
To install the 2.4GZ OpenWay Remote Mount Gas Module on an Elster
American RPM series meter
1. Remove the meter's top plate by removing the two (2) 5mm screws and carefully
prying up on the plate. The plate is secured with an o-ring seal. Remove the o-ring
from the plate.
Caution If the o-ring is damaged during removal, obtain a replacement from
Elster American Meter Co.
2. Look into the meter tower and find the meter switch lead and connector (4-pin).

Installing the 2.4GZ OpenWay Remote Mount Gas Module to the Elster American Meter RPM Series Rotary Meter
3. If the lead and connector are not visible or cannot be found, remove the four (4) 5mm
mounting screws and the register cover. The meter switch lead and connector will be
visible inside the cover.
Note Save any meter tags. You will re-install them later in the installation
process.
4. Feed the lead and connector into the register cover tower.
5. If you removed the register cover, replace the cover using the four (4) 5mm mounting
screws.
6. Attach the 4-pin male connector on the Elster American Meter adapter plate to the 4pin female connector inside the meter's tower. The connectors will slide together and
latch.
7. Carefully push the connectors and wires into the meter tower housing.

Rotary Meter Installation
8. Lubricate the o-ring with o-ring lubricant and install the o-ring on the adapter plate.
Insert the adapter plate into the tower and tighten the (2) 5 mm screws.
To connect the manufacturer cable to the endpoint
Note Connection to an Elster American Meter requires a cable interface
compatible to an Elster American Meter RPM rotary meter.
1. Trim the 2.4GZ OpenWay Remote Mount Gas Module wires to 3.5".
2. Carefully strip the insulation covering from the meter cable (purchased from the meter
manufacturer) approximately 1 1/2" from the end.
Caution Do not cut through the individual wire insulation.
3. Separate the black, white, and blue wires for connection to the 2.4GZ OpenWay
Remote Mount Gas Module. Cut off the unused wires even with the outer covering
(insulation).
Caution Do not strip the individual wires.

5. Insert the meter cable through the slot on the module backplate. Install a cable tie to
the meter cable wire below the meter cable insulation to provide strain relief.
6. Tuck the connectors and cable tie into the endpoint housing. Place backplate on the
assembly and tighten the four backplate screws using a size T-10 Torx screwdriver.

Mounting the 2.4GZ OpenWay Remote Mount Module
To install the 2.4GZ OpenWay Remote Mount Gas Module cable
1. Insert the plug on the cable connected to the module into the receptacle on the meter
adapter plate.
2. Tighten the threaded collar on the plug onto the Amercian Meter interface receptacle.
Verify the connection is hand-tight.
Mounting the 2.4GZ OpenWay Remote Mount Module
Select an appropriate mounting location on adjacent piping close to the meter. Using the
pipe bracket, mounting plate and band clamps from the Remote Mount Kit (Itron part
number CFG-0005-003), secure the 2.4GZ OpenWay Remote Mount Gas Module. Use the
cable ties from the kit to secure any excess wire to the piping (see Mounting the 2.4GZ
Remote Mount Module on a Pipe on page 10).

Rotary Meter Installation
Installing the 2.4GZ OpenWay Remote Mount Gas Module to
the Romet Electronically Compensated Meter (ECM2® )
The Romet ECM2® meter has three Form "A" outputs that can be configured at the factory
to provide any combination of the following three outputs:
•
Uncorrected volume (UNC VOL)
•
Corrected volume (COR VOL)
•
Alarm
The pulse weight for the volumetric outputs is configured in SetUp Mode at Menu
items>SET UNC OUT and SET COR OUT. Since Setup Mode is fully configurable, the
ECM2® module is universally adaptable to all Romet TC meter bodies. Reference the
Romet technical manual for specific details on the ECM2®.
