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 pump/dispenser. To assure a quality
installation, follow these rules:
• All wiring is to be installed and used in accordance with local building/fire codes, all
Federal, State, and Local codes, the National Electrical Code (NFPA 70), NFPA 30, and
the Automotive and Marine Service Station Code (NFPA 30A) codes and regulations.
Canadian users must also comply with the Canadian Electrical Code.
• Use approved conduit and insulated gasoline and oil resistant copper wiring of the proper
size.
• Wire connections must be tightly spliced and secured with a wire nut; close off the open
end of the wire nut with electrical tape.
• Install an emergency power cutoff. In addition to circuit breaker requirements of NFPA
70, NFPA 30, NFPA 30A and the Canadian Electrical Code (Canadian users only), 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 local codes.
The Disable Pumps button on the Series 1000 will cut all control power to the solid-state
relays of the pump control unit, which should stop product flow. However, AC power will still
be present at the Series 1000 and may be present at some site dispensing equipment.
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.
To reduce the risk of electrical shock when servicing, turn off all power to the pump/
dispenser. In submersible pump applications, turn off all power to the submersible pump
and any other 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.
