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 the rules below:
• 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 also 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 electrical tape.
• The line to the motor should be on a separate circuit and fused to carry 20 to 30 Amp
depending on the motor size and/or the voltage setting.
• Install an emergency power cutoff switch. 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.
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 be 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 that 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.
AVERTISSEMENT !
