General Wiring Precautions
The quality of the electrical installation is a major factor in maintaining proper safety levels
and providing trouble-free operation of your Gasboy CFN System. To ensure a quality
installation, follow these rules:
• 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 (NFPA 30A) codes and regulations. Canadian
users must comply with the Canadian Electrical Code also. Wiring must conform to the
wiring diagram supplied with the pump/remote dispenser.
• Use approved conduits and insulated gasoline and oil-resistant wiring of the proper size.
• Wire connections must be tightly spliced and secured with a wire nut. Close the open end
of the wire nut with an electrical tape.
• Install an emergency power cutoff switch. In addition to circuit breaker requirements of
NFPA 70, NFPA 30, and NFPA 30A, a single control that simultaneously removes AC
power from all site dispensing equipment is recommended. This control must be readily
accessible, clearly labeled, and must be in accordance with all local codes.
In a fuel management system application, the Disable Pumps and Stop keys on the console,
and/or the optional Disable Pumps button on the ICR do not remove AC power from the
equipment and will not stop product flow under certain conditions.
In order to provide the highest level of safety to you, your employees, and customers, Gasboy
recommends that all employees be aware of the location and are trained on the procedure for
turning off power to the entire system.
To reduce the risk of electrical shock when servicing, turn off all power to the pump/remote
dispenser. In submersible pump applications, turn off all power to the submersible pump and any
other remote dispensers that use the submersible pump. AC power can feed back into a shut-off
remote dispenser when dispensers share a common submersible pump or starter relay.
WARNING
!
Pour réduire le risque de choc électrique lors de l'entretien/révision, coupez totalement le courant à
la pompe/distributeur. Dans les applications de pompe immersible, coupez totalement le courant à
la pompe immersible et tous autres distributeurs qui utilisent la pompe immersible. Le courant
alternatif peut alimenter de nouveau un distributeur à l'arrêt quand les distributeurs partagent une
pompe immersible commune ou un relais de démarrage.
