Conduit Layout/Installation Specifications
• All wiring is to be installed and used in accordance with local building/fire codes, all
Federal, State, and Local codes, the National Electrical Code (NFPA 70), NFPA 30, and
the Automotive and Marine Service Station Code (NFPA 30A) codes and regulations.
Canadian users must also comply with the Canadian Electrical Code.
• All peripheral equipment connected to the RS-232 ports must be UL-listed, have an
Electronics Industrial Association (EIA) standard RS-232 communications protocol and
not be installed over a hazardous location.
• Power for the system, printer and modem must come from a separate circuit breaker rated
at no less than 10 AMPS.
• All conduit must be metal to provide the necessary shielding.
• High-voltage (AC) and low-voltage (DC) must not be combined in a common conduit,
junction box, or wire trough unless cable is used as specified in “System and Pump/
Dispenser Wiring” on page 17 or “Communication Wiring” on page 51 .
• Use the Wire Size chart (see Figure 4-2 on page 21 ) to determine the proper wire gauge.
• Use the Conduit Size chart (see Figure 3-3 on page 13 ) to determine the proper conduit
size.
• RS-232 communication must not exceed 100 feet. RS-232 communication wires must be
in a separate metal conduit from any AC wires.
• For communication distances exceeding 100 feet, you must use a Gasboy RS-422 Short
Haul Modem.
• DC pulser and DC RS-422 communication wires can be combined in the same conduit.
• Suction pumps over 3/4 HP at 115/230 VAC must use a starter relay. Wire the starter relay
in place of the motor in the applicable pump wiring drawing.
• A minimum of 18 inches must be maintained between the Series 1000 post and any of the
pumps/dispensers.
• Disregard submersible pump in drawing if hose outlets are suction pumps.
Conduit Requirements
All wiring (AC and DC) connecting the different components of the Gasboy Fuel Management
System must be installed in threaded, rigid, metal conduit except as noted in
“Installation
Notes” on page 51 and “Short Haul Modem - RS-422” on page 58 . PVC IS NOT
ACCEPTABLE. Components of the system include pumps, dispensers, submersible pumps,
submersible starter relays, the circuit breaker panels and the Series 1000 system.
Communications equipment signal wires must also be run in metal conduit, except for RS-422
wiring as noted in
“Communication Wiring” on page 51 .
Communication equipment signal wires must also be run in metal conduit. High-voltage (AC)
and low-voltage (DC) must not be combined in a common conduit, junction box, or wire
trough unless cable is used as specified in
“System and Pump/Dispenser Wiring” on page 17
or “Communication Wiring” on page 51 .
All conduits must be connected to the Series 1000 pedestal through the holes and knockouts
provided by the factory. Do not make any other holes in this unit. If you must make holes at
locations other than those provided, contact Gasboy for approval first.
