SYSTEM POWER
1. Verify that the AC power for the CFN Series System is in accordance with the Site Controller
II or Islander II Installation Manual. AC Power for the CFN system components, CRT
terminal/printer, and external modem 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 power conditioner 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 an AC
surge protector strip.

Record the Grounding method as outlined in Step 2. Then, record voltage readings for each
component from Step 4 for Hot to Neutral, Hot to Ground, and Neutral to Ground.
2. Proper system grounding is an extremely important part of the system installation. 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; 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:
Power conditioner -- On the output receptacle
Islander -- at TB2
AC surge protector strip -- On the output receptacle
Pump control unit(s) -- at TB202
Island card reader(s) -- at TB6
Hot to Neutral: AC voltage measured between the H and N screws. This voltage
should be 120 VAC + 10%. (108 VAC to 132 VAC).
Hot to Ground: AC voltage measured between the H and G screws. This
voltage should be 120 VAC + 10% (108 VAC to 132 VAC).
Neutral to Ground: AC voltage measured between the N and G screws. This
voltage should be 0 VAC + 1 volt.
NOTE: If power is not within these specifications, correct it before you continue.
