All wiring to the Gasboy Series 9800Q dispensing unit must be installed in threaded, rigid,
metal conduit. PVC is not acceptable. When the Series 9800Q dispensing unit is used with a
Gasboy Fuel Management System, it is recommended that AC power wires be installed in a
separate conduit from the DC wires; they should not run in any sort of common conduit or
trough. However, if AC and DC power wires share conduit, DC wiring must use the cable as
“Pulse Output or RS-485 Wiring” on page 5-5
. Wiring between a Fuel Point
Reader (FPR) and its pre-amp junction box is intrinsically safe and must be run in a conduit
with only other intrinsically safe wiring. It cannot be run in conduit with AC, DC, RS-485, or
pulser wiring, regardless of the cable type used. See the Fuel Point Reader Installation and
Retrofit Instructions Manual, C35628 for details.
When using a Fuel Management System other than a Gasboy system, see the manufacturer's
installation manual for specific conduit requirements. All wiring and conduit runs must also
conform with the National Electrical Code (NFPA 70) and the Automotive and Marine
Service Station Code (NFPA 30A). All wiring and conduit runs must conform to local codes.
Canadian users must also comply with the Canadian Electrical Code.
Use the charts below as a guideline to determine the proper conduit sizes for the Gasboy Series
9800Q dispensing unit. When planning the orientation of the wiring runs, follow the
applicable Gasboy wiring diagram and consider the layout of the components at the site. Long
runs or a large number of bends may require you to increase conduit size over what is listed.
