Wiring Overview
The quality of the electrical installation is a major factor in maintaining proper safety levels
and providing trouble-free operation of your Gasboy pump/remote dispenser (refer to
on
). To assure a quality installation, follow these rules:
1
All wiring must be installed to conform 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
Use only threaded, rigid, metal conduit. For more details, refer to
on
3
Use only UL-labeled, insulated, gasoline and oil-resistant stranded copper wiring of the proper
size (refer to
).
4
Wire connections must be tightly spliced and secured with a wire-nut. Close off the open end
of the wire nut with electrical tape.
5
The line to the motor must be on a separate circuit and installed on a 20 to 30 A breaker
depending on the motor size and/or the voltage setting (refer to
).
6
Install an emergency power cutoff (refer to
“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 from all fueling positions, clearly labeled, and in
accordance with all local codes.
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.
7
To provide the highest level of safety to you, your employees, and customers, all employees
must be trained as per the location and 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 power to the submersible pump and
any other remote dispensers which use that submersible pump. AC power can feed back
into a shut-off dispenser when dispensers share a common submersible pump or starter
relay.
WARNING
8
The distinction between the Commercial and Retail pump/dispenser units is that the
Commercial unit must use the separate conduit arrangement to keep the signals from
interfering with one another or other noise generating devices whereas with the Retail unit this
is not required.
9
Ensure that the pump/remote dispenser is installed by a competent installer/electrician.
