Installing an Itron ERT Module
To install an Itron ERT® (encoder receiver transmitter) module on the meter, perform the following steps:
Splice the meter pulse output wires to the ERT.
•
If using Pulse Output 1, the green meter wire
connects to the red AMR wire and the brown
meter wire connects to the white AMR wire.
•
If using Pulse Output 2, the black meter wire
connects to the red ERT wire and the white
meter wire connects to the white ERT wire.
Note:
You do not need to strip the wire
as the gel cap splices supplied with the
ERT are IDC (insulation displacing
connection) type connectors. Use
appropriate crimping pliers as shown in
Figure 25 to properly clamp the splice.

cap splice
After the ERT is properly wired, install the supplied
cable tie approximately 1/8 inch from the end of
the shrink tubing as shown in Figure 26.

Slide the cable into the slot on the ERT back plate as shown in Figure 27. Ensure the cable tie is
toward the inside of the ERT to provide a strain relief for the cable. When mounting the ERT
assembly to the meter mounting bracket, route the cable across the back plate as shown in Figure 28
to prevent pinching the cable.
