1 Introduction
1.1 Scope
This document provides the instructions for the retrofit of the Tantalus TUNet meter modules into single-phase meters. The
meters covered in this document include the GE I-70-S, ABB AB-1, GE I-210, and the Itron CENTRON.
1.2 Overview
The entire retrofit process should take approximately ten minutes per meter once a technician is familiar with all the steps
involved. This procedure includes instructions for the following basic steps:
• Drill a hole in the meter base to mount the IR (infrared) serial interface for the meter module.
• Mark the disk for reading by the optical sensor on the module (eletromechanical meters only).
• Mount the IR serial interface.
• Connect the power from the host meter to the TUNet module.
• Mount the TUNet module into the host meter.
• Program the TUNet module with the utility operating parameters.
1.3 Required parts
The following items are required for the TUNet meter module installation:
• GE I-70 and ABB AB-1 (240V)
o One (1) TC-1205 meter module for 200 class service or one (1) TC-1207 for 320 class service
o One (1) infrared LED serial interface
o Two (2) mounting screws: UNF 4-48 x ½” required for the GE I-70S meter
o Two (2) power clips to attach to bus bars. The part number is dependant on the meter bus bar diameter.
• GE I-210 (240V)
o One (1) TC-1210 module
o One (1) infrared LED serial interface
o Two (2) Y-clips are required for the TC-1210 module.
• Itron CENTRON
o One (1) TC-1216 meter module for 240V or one (1) TC-1116 meter module for 120V
o One (1) infrared LED serial interface
