a voltage to current sense converter. This signal is provided by a solid state device. Be sure
to verify the signal is being properly communicated to the control device.
Basic features of the reset output include:
 One output
 Typical voltage output of 120VAC or 240VAC (optional); maximum current rating of one
(1) amp for 120 VAC and 0.5A for 240 VAC (optional)
 Neutral line is provided for reference, but the dispenser and control system should be
powered from the same breaker panel so they already have a common neutral reference
3.3.4 Circuit Breakers & Emergency Electrical Disconnect
 A primary requirement in dispenser installation wiring is to provide a means for
disconnecting all power connections, including the neutral and data wires, to the
dispensers for a safe shutdown and servicing of the units. The power to the electronic
register (control power) should be on a separate dedicated breaker for each dispenser.
No other equipment should be on this breaker. For sites with multiple dispensers, if it is
not practical to use separate breakers for each dispenser, the number of dispensers that
can be included on one breaker is determined by analyzing the power requirements of
each dispenser to determine the total load required for the group of dispensers. The
breaker and wire must be sized accordingly for that load and the length of the wire run.
In multiple dispenser installations, all dispensers operating the same submersible starter
relay must be on the same phase of power or must control the common starter relay
through an isolation box.
 If the dispenser is equipped with an optional heater (290 W), a separate breaker is
recommended for each dispenser with no more than two (2) dispensers per breaker.
 A separate circuit breaker must be provided for each submersible pump.
 Both legs of any AC circuit must be broken for the emergency disconnect.
 If a fuel control system and/or tank monitoring system are used with the dispenser, all
should be powered from the same breaker panel so they can share a common neutral.
In addition to the circuit breaker requirements, in accordance with local, state, and federal
regulations, the fueling site should include a clearly identified emergency electrical disconnect
switch that simultaneously removes power to all of the electrical equipment installed in the
hazardous classified areas of the fuel site, including, but not limited to, the fuel dispensers,
submersible pumps, and fuel control systems. The switch should be located within a convenient
distance of the fueling equipment and all employees and fuel site users should be trained on the
location and function of the emergency switch.
3.3.5 Grounding
 All dispensers and electrical connection boxes must be grounded per NFPA 70.
 Connect a ground wire between the terminal block ground lug and the main electrical
service panel. Do not use the electrical conduits as the sole grounding source.
 Make sure a ground rod is properly installed and wired to the ground bus strip of the main
electrical service panel in accordance with the National Electrical Code. Unless prohibited
by local regulations, it is recommended that the neutral and ground bus strips be tied
together.
