Wiring Precautions
Note: For any questions pertaining to the installation, contact Gasboy distributor.
The quality of the electrical installation is a major factor in maintaining proper safety levels
and provides trouble-free operation of Gasboy pump/dispenser. To assure a quality
installation, follow these rules:
• All wiring must be installed to conform with all building/fire codes, all Federal, State, and
Local codes, NEC, (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.
• Use the proper wiring diagram. This manual contains instructions for wiring mechanical
and electronic units. Using the mechanical wiring diagram for an electronic pump will
cause CPU PCB damage to the electronic pump.
• Use only threaded, rigid, metal conduit.
• Use only UL-labeled insulated gasoline- and oil-resistant stranded copper wiring of the
proper size.
• Wire connections must be tightly spliced and secured with a wire nut. Close the open ends
of the wire nut with an electrical tape.
• The line to the motor must be on a separate circuit and installed on a 20 to 30 Amp breaker
depending on the motor size and/or the voltage setting.
• Have the pump/dispenser installed by a competent installer/electrician.
• Install an emergency power cutoff. In addition to circuit breaker requirements of NFPA 70
and NFPA 30A, a single control which simultaneously removes AC power from all site
dispensing equipment is recommended. This control must be readily accessible, clearly
labeled, and in accordance with all Local codes.
To reduce the risk of electrical shock when servicing, turn off all power to the
pump/dispenser. In submersible pump applications, turn off power to the submersible
pump and any other dispensers which use that submersible pump. AC power can be fed
back into a shut-off dispenser when dispensers share a common submersible pump or
starter relay.
WARNING
In a fuel management system application, the EMERGENCY STOP and STOP keys on the
console and/or the optional EMERGENCY STOP button on the Island Card Reader do not
remove AC power from equipment and under certain conditions, will not stop product flow.
In order to provide the highest level of safety to you, your employees, and customers, we
recommend that all employees be trained as to the location and procedure for turning off
power to the entire system.
