MDT to Meter wiring
Wiring an MDT to a pulse output meter is quite simple. From the factory the MDT’s can
optionally come pre-wired with about 24 inches of pre-stripped wire. If a longer length is
required, it is easy to switch wires. Polarity of the wires does not matter since the MDT simply
detects the open/close nature of the isolated pulse output switch from the utility meter.
To add or switch pulse input wires:
• Unscrew single screw to open the case
• Locate the green connector shown in the image above. Push down on the little button with
a flat blade screw driver to release the old wire.
• Repeat to insert a new 3/8 inch stripped wire into the opening. Up to a 22 gauge wire,
stranded or un-stranded, can be used. It is convenient to angle the wire about 30 degrees
from vertical when inserting them into the connector.
• Release the button to secure the wire.
• Route the wire pair through the hole in the enclosure. Wrapping the wire around one
battery can provide some strain relief. Allow for an extra five inches in wire length if doing
this.
• Close the case and secure with the screw.
