1. Remove the ERT module backplate (4 screws) to
expose the module lead wires. The backplate and
screws will be re-installed on the ERT module later
in this procedure so store them (temporarily) in a
safe, secure place.
2. Insert the lead wires from the module into new 3M gel connectors (Itron part number
CON-0023-001) together with the lead wire from the meter cable (see wiring connections).
3. Crimp the connectors 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 connectors. For more information, see Using gel-cap connectors to complete wiring
connections on page 72.
