CONDUIT LAYOUT/INSTALLATION SPECIFICATIONS
1. All wiring is to 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.
All peripheral equipment connected to the RS-232 ports must be Listed, have an Electronics
Industrial Association (EIA) standard RS-232 communications protocol and not be installed
over a hazardous location.
3.
Power for the system components, data terminal, and modem must come from a separate
dedicated circuit breaker rated at no less than 10 AMPS.
4. All
conduit must be metal to provide the necessary shielding.
5. All
conduit must be run underground, not overhead.
6.
DC pulser and DC RS-485 and RS-422 communication wires can be combined in the same
conduit. It is recommended that the DC pulser, RS-485 and/or RS-422 wiring be in a
separate metal conduit from any AC wires. However, the DC pulser, RS-485 and/or RS-422
wires can share conduit with AC wires if shielded cable is used as specified in Section 3,
Communication Requirements (RS-485), Short Haul Modems (RS-422), and/or Section
4, Pulser Wiring and Configuration.
7.
Use the wire size chart (Table 4-1) to determine the wire gauge.
8.
Use the conduit size charts to determine the size according to the number of wires and wire
gauge.
9.
RS-232 communication must not exceed 100 feet. RS-232 communication wires must be in
a metal conduit separate from any AC wires.
10. For communication distances exceeding 100 feet, you must use a GASBOY short haul
modem.
11. In submersible applications, starter relays are always recommended; however, the system
can directly drive motors up to 3/4 HP at 120/240 VAC or 1-1/2 HP at 240 VAC.
12. Suction pumps over 3/4 HP at 120/240 VAC or 1-1/2 HP at 240 VAC must use a starter relay.
Wire the starter relay in place of the motor in the applicable pump wiring drawing.
13. A minimum distance of 18 inches must be maintained between the Islander post and any of
the pumps/remote dispensers.
14. Disregard the submersible pump in the drawing if the hose outlets are suction pumps.
15. Consult the applicable section of this manual for specific system installation requirements.
16. When used with Fuel Point, an extra dedicated junction box is supplied to be installed in the
pump/dispenser. A separate dedicated conduit is to be run between the junction box and the
Fuel Point Reader. Consult the Fuel Point Reader Installation Manual C35628 for details.
