Mounting the 100G Series Remote Gas Module

TDC

Mounting the Remote Gas Module on a Wall or Other Flat
Vertical Surface

1. Using one of the three 1-1/2-inch mounting screws from the Remote Mount Installation Kit, turn the

mounting screw for the mounting lug (top of module) part way into the mounting surface.

2. Place the 100G series remote gas module mounting lug recess (on the top of the module backplate) just

under the screw head.

3. Slide the module upward until the screw head fits completely inside the mounting lug recess. Several

adjustments may be necessary to properly position the screw for module mounting.

4. Install the bottom two mounting screws. Fasten the screws in an alternating pattern until fully tightened to

secure the module firmly in position.

Note For easier installation, drill three pilot holes in the mounting surface (use the correct size drill bit to
accommodate the module mounting screws [see the drilling template below]). The drilled pilot holes for
the two bottom screws must be on a horizontal line. To mount the module on a sheet metal surface, use
the mounting screws included with the Remote Mounting kit. Use a comparable wood screw to mount the
module on a vertical wood surface.

Mounting the 100G Series Remote Gas Module

Carefully select a mounting location free from electrical wires. The mounting location must have the
proper clearance to accommodate the 1-1/2-inch module mounting screws so nothing is damaged by the
drill or mounting screws.

To install tamper seals and cable ties

1. Place a new tamper seal (from the Remote Mount Installation Kit) over each ERT module mounting

screw.

2. Firmly push both tamper seals into place with a 1/4-inch nut driver or similar blunt tool.

Note A tamper seal is fully seated when the top of the tamper seal is approximately 1/16-inch below the
top of the screw recess.

3. To reduce the risk of cable damage, secure the excess module cable with the cable ties from the Remote

Mount Installation Kit. Pull the cable tight. Remove and properly dispose the excess cable tie.

Required Installation Materials Available from Itron

The materials in the following table are required to install a remote 100G DLS module.

Itron Part Number

ERG-5003-503
ERG-5006-503

Note this remote ERT module comes standard with 12-inch lead wires and may
be shipped directly to the meter manufacturer for a factory-installed cable
(interface). The interface cable must be purchased directly from the meter
manufacturer.

Connecting the 100G Remote Gas ERT Module to the GE
Dresser Rotary Meter Cable

You may ship the Itron 100G series remote gas module directly to GE Dresser for a factory-installed cable. If
you connect the module to the meter using an existing cable purchased from GE Dresser, complete the
following cable installation procedure.

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

Rotary Meter Installation

To connect the remote module to the rotary meter cable

Rotary Meter to Remote ERT Module Wire Table

1. Remove the backplate (4 screws) from the remote module and expose the module lead wires. The

backplate and screws will be re-installed on the remote module later in this procedure so store them
(temporarily) in a safe, secure place.

2. Insert the lead wires from the remote 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.

Important Use a crimping tool compatible with gel-connectors. Do not use a standard pliers for crimping
gel-connects. The crimping tool provides an even pressured crimp to make a secure connection. Apply
pressure for three seconds until the gel cap is fully crimped (collapsed) to allow time for the low viscosity
silicone-based gel to flow (3). If the silicone gel flows out of the crimped connector, avoid touching the
gel. Gel flowing from the connector provides environmental protection for the connection.

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