Optional Smart Output Hook Up
The convertor comes pre-wired with an
interconnection that should readily connect to
most AMI transceivers. Where interconnective
devices are not mechanically compatible or where
non-standard wiring is encountered, the installer
can opt to remove the connector from the end of
the converter’s interface cable and make direct
connection via the wiring table shown at right.

Signals and associated wire colors in the
McCrometer SmartOutput™ interface cable are

Corresponding wire colors for transceivers from
each compatible AMI vendor are identified in
the columns under the top row.

Information For Grounding Ring Installations
• Gaskets must be used on either side of the grounding ring to provide a proper seal on the flanges. One
gasket is used on flanges without a grounding ring.
• Rings & gaskets must align concentrically with the pipe so they do not obstruct or affect flow through the
tube.
• The two grounding rings and four gaskets require an additional installation width of 0.375”.
Always ensure that the converter and the sensor are grounded (earthed) correctly. The grounding of the sensor and
converter ensures that the equipment and liquid have an equal potential. For most installations the quality of grounding
by the provided cabling assures the sensor is properly grounded and additional grounding of the sensor is not required.
However, in instances where this is not the case, i.e. the equipment and fluid do not have an equal potential, such as where
the installation location and/or media is subjected to electrical interference, additional grounding steps may be required.
Consult an electrician experienced with instrumentation installations to determine if electrical interference is present.

On meters installed on a line with cathodic protection it may be necessary to insulate the meter from the line.
Consult your cathodic protection vendor for instructions.
