POWER REQUIREMENTS
System/Peripheral Equipment
Breakers AC Power for the Series 1000 System, data terminal, and external modem must
come from a separate, dedicated circuit breaker. No other equipment, including
the system’s pumps or dispensers, may be powered from 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 different separate,
dedicated breaker. The power supplied from these breakers must be on the
same phase of power.
Power Protection The system requires 115 VAC + 10% 47-63 HZ for power. The system draws
135 watts maximum. An unstable power source may require the use of a power
conditioner (P/N C01862) If the Series 1000 is going to be used for the resale of
fuel, Weights and Measures regulations require a voltage regulator/backup power
supply (P/N C04395).
Grounding 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 when it is not prohibited by local codes.
Suction Pumps
Guidelines The Series 1000 System is capable of directly driving pump motors up to 3/4 HP
at 115 VAC or 230 VAC. A starter relay must be used with pump motors over 3/4
HP. A separate circuit breaker should be supplied for each pump to meet the
current requirements and to allow for isolated control with the circuit breaker
panel in case of problems.
Dispensers
Guidelines The Series 1000 System is capable of directly driving submersible pumps up to
3/4 HP at 115 VAC or 230 VAC. A separate circuit breaker should be supplied for
each dispenser in cases where it will directly drive the submersible pump. A
dispenser with a submersible pump rated over 3/4 HP will require the use of a
submersible starter relay. Dispensers may be grouped together on a single
breaker when the submersible pump has its own breaker. It is recommended that
no more than two dispensers be powered from one breaker to maintain isolated
control with the circuit breaker panel in case of problems.
TERMINAL BLOCK ID
Description All wiring for the Series 1000 is terminated to the chassis assembly in the
pedestal of the system. Terminal connectors should be used on stranded wire
when connecting to the terminal blocks of the system. The orientation of the
chassis assembly is shown in Figure 5-5.
