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 Electric Keytrol and your pump/remote
dispenser. 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.
3. Use only UL-labeled, insulated, gasoline and oil-resistant, stranded copper wiring of the
proper size.
4.
Wire connections should 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 should be on a separate circuit and installed on a breaker sufficiently
sized for the motor size and/or the voltage setting.
6.
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.
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.
WARNING:
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.
7. Have the Electric Keytrol and the pump/remote dispenser installed by a competent
installer/electrician.
