Wiring Requirements
• Wire all pumps/dispensers according to NFPA 30A, NFPA 70, and applicable national,
state, and local codes/regulations.
• Wire all circuits N.E.C Class 1.
• Use stranded gas and oil resistant copper wire rated for 300 V (up to 240VAC source) and
80 °C.
• In the main conduit of Retail units, for communications, use only twisted-pair, Two-wire
data pairs. Do not use shielded twisted-pair wiring.
• Unshielded twisted-pair wire is required per the following:
— Retail Two-wire communication wiring for new installations.
— Replacement units, depending on location of the wiring conduit and previous unit style,
may require new wiring or adaptive conduit, explosion proof junction box, and jumper
wiring to mate with the old wiring.
— Previously wired stations may continue to use tested existing non-twisted-pair wiring
that has been short and continuity tested and passed, where communication problems
between the older units and console have not been a problem. Twisted-pair wiring is
highly recommended for existing stations experiencing higher than national average
lightning strikes or for stations previously experiencing console to dispenser
communication problems.
• Leave 3-feet of wire out of conduit for connection to dispenser.
• Place dispensers on the same phase.
Note: If Gasboy isolation relay box is installed, dispensers are not required to be on the
same phase.
• Use listed wire nuts for all connections. Do not use tape.
• Pull spare wires for future use.
• Protect conduit ends and wire from water or damage prior to installation of the
pumps/dispensers.
• Seal-off ‘Y’ fitting(s) must be potted after all wires are run to termination points.
For additional wiring notes and requirements, refer to the following documents:
• FE-356 Atlas Retail/Commercial Dispenser Field Wiring
• FE-357 Atlas Pump Retail/Commercial Field Wiring
• FE-361 Atlas Master & Satellite Field Wiring Diagram
