6 – System Power
1 Verify that the AC power for the CFN Series System is in accordance with the Site Controller
III Installation Manual. AC Power for the CFN system components, monitor, printer, external
modem, and remote terminal must come from a separate, dedicated circuit breaker. No other
equipment, including the system’s pumps or dispensers, should be powered from this breaker.
Gasboy recommends all CFN components be on the same breaker; however, it is acceptable to
supply the power to the different CFN system components and accessories from multiple
breakers within the same breaker panel. When necessary, power for the data terminal or
modem may be supplied from a separate, dedicated breaker located in a different breaker
panel.
Power for the system should be 120 VAC + 10% 47-63 HZ. Power for the CFN system
components must come from the AC Surge Protector Outlet Strip supplied with the system
(except for the pump control unit, island card reader, electronic pumps/dispensers, and the
Profit Point). The Profit Point and its accessories (scanner, PIN pad, etc.) must be plugged
into another AC surge protector strip.

Grounds for all system devices should be wired to the breaker panel ground bus bar which, in
turn, should be grounded to a single ground rod. A conduit ground does not provide a
sufficient ground. It is recommended that the neutral and ground bus bars be bonded together
unless prohibited by local codes.
3 Be sure all power switches for the system’s devices are in the OFF position. Turn on the
circuit breakers for the system’s devices; optional power conditioner, pump control units, and
island card readers and turn on the AC surge protector switch.
4 On the specified locations of the following components, use a digital AC voltmeter to test and
record the voltages as follows:
• Optional power conditioner - on the output receptacle (see Figure 6-1 )
• AC surge protector strip - on the output receptacle (see Figure 6-1 )
• Pump control unit(s) - at TB202
• Island card reader(s) - at TB6

Record the Grounding method as outlined in step 2 below. Then, record voltage readings for each
component from step 4 for Hot to Neutral, Hot to Ground, and Neutral to Ground.
Proper system grounding is an extremely important part of the system installation.
