Rotary Meter Installation
To connect the ES3 or ETC and 100G ERT module wires
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 Connecting the ES3 or ETC to the 100G remote module requires 3M gel cap connectors. Itron
supplies the two-wire gel cap connectors. Users who want to complete three-wire connections must
supply the 3M UR2 connectors.
1. Splice the meter wires to the ERT module wires using gel cap connectors. Follow the wire connections in
the following wire connection tables.

Note See the 100G Series Remote ERT Module Meter Compatibility List on page 4 for pulse requirements
and compatibilities.
Caution
If alarm functionality is not required, at a minimum, you must tie the white and blue ERT module
wires together. Wiring the white and blue ERT module wires together, eliminates the possibility of the ERT
module falsely incrementing cut cable tampers.
2. Clip off the unused green, red, and shield wires from the ES3 cabling.
3. Tuck all of the wires into the module's housing.
