Wiring Reference Information
Atlas Retail
The Atlas retail pump/dispenser utilizes only one main conduit as it does not require a DC
conduit. The AC conduit is used to carry the AC wire and the two-wire interface twisted-pair.
The distinction between commercial and retail pumps/dispensers units is that the commercial
unit uses a separate conduit arrangement to keep signals from interfering with one another or
other noise generating devices, whereas in the retail unit it is not critical.
When installed in a separate DC conduit, 18 AWG wires are required for the installation.
Although it is recommended that DC commercial pump interface wires (RS-485 or pulse
output) be run in a conduit away from AC wires, they can be combined in the same conduit
with AC wires, provided that a UL-listed cable with the following specifications is used:
Gasboy can supply Belden ® 1063A (part number C09655), which is a UL-listed,

four-conductor cable that meets the requirements listed above.
Note: Belden 1063A is UL-listed but not CSA-listed.
