Section 7
SYSTEM POWER
1. Verify that the AC Power for the Series 1000 System comes from a separate, dedicated
circuit breaker. No other equipment, except for data terminals or external modems should be
powered from this breaker. The system’s pumps or dispensers must not be on this breaker.
Whenever possible, one breaker should be used to supply the system, terminal, and modem.
However, if necessary, the terminal or modem may be on a separate, dedicated breaker.
Power for the system should be 115 VAC + 10%, 47-63 HZ. The system draws 135 watts
maximum. An unstable power source may require the use of a voltage conditioner.
(GASBOY P/N C01862). If the Series 1000 is going to be used for the resale of fuel, Weights
& Measures regulations require a backup power supply (GASBOY P/N C04395).
CAUTION
AC power is present on the terminal blocks in the pedestal. Electrical shock may
occur if the operator comes in contact with these connections.
2.
Turn on the circuit breaker for the system.
3. Locate
the SYSTEM POWER terminal block in the pedestal on the chassis assembly (see
Figure 5-1). Use a digital AC voltmeter to measure the following voltages. Holes in the
plastic cover provide access to the terminal block for your meter leads.
Hot to Neutral: AC voltage measured between the H and N screws. This voltage
should be 115 VAC + 10% (104 VAC to 126 VAC).
Hot to Ground: AC voltage measured between the H and G screws. This voltage
should be 115 VAC + 10% (104 VAC to 126 VAC).
Neutral to Ground: AC voltage measured between the N and G screws. This voltage
should be 0 VAC + 1 volt (-1 VAC to 1 VAC).
NOTE: If power is not within these specifications, correct it before you continue.
4. Grounding Method:
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 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.

7. SYSTEM POWER
Record voltage readings from Step 3 for Hot to Neutral, Hot to Ground, Neutral to Ground, and
the grounding method from Step 4 for Grounding Method (e.g., system to circuit breaker panel
bus to ground rod).
