CONDUIT LAYOUT/INSTALLATION SPECIFICATIONS
1.
All wiring must be installed and used in accordance with all building/fire codes, all Federal,
State, and Local codes, National Electrical Code (NFPA 70), NFPA 30, and Automotive and
Marine Service Station Code (NFPA 30A) codes and regulations. Canadian users must also
comply with the Canadian Electrical Code.
2.
Power must come from a separate dedicated circuit breaker rated at no less than 10 AMPS
or may share the fuel management system breaker. When mounted to an island pedestal
(factory or retrofit), the FPR will get its power from the pedestal device via a GASBOY-
supplied AC power cable.
3.
All conduit must be rigid metal to provide the necessary shielding.
4.
All conduit must be run underground, not overhead.
5.
The I/S Pre-Amp comes factory-installed in a metal junction box and mounts in the base of
the pump or dispenser. Twin pumps or dispensers have two Pre-Amps mounted in the same
junction box. The box is secured by threading onto conduit. It can be mounted wherever it is
convenient as long as it does not interfere with other dispenser components. The junction
box has 1/2 inch hubs, so you need to use a reducer if running larger conduit for the I/S
wiring. Strain relief connectors must be used to protect the N-ring wiring entering the box.
I/S Pre-Amp wires are intrinsically safe and must be in a separate conduit from any AC
or DC wires. The distance between the Pre-Amp and the Fuel Point Reader cannot exceed
1000 feet.
6.
It is recommended that the RS-485 wiring be in a separate metal conduit from any AC wires.
However, the RS-485 wires may be run in the AC conduit if the requirements outlined in
Communication Requirements (RS-485) in Section 3 are followed.
7.
Use the wire size chart (Table 4-1) to determine the wire gauge.
8.
Use the conduit size chart (Table 2-1) to determine the size according to the number of wires
and wire gauge.
9.
Consult the applicable section of this manual for specific system installation requirements.
