Power Requirements
System/Peripheral Equipment
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 separate, dedicated breaker within the same breaker panel and on the same phase of
power.
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. 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 (Gasboy Part Number C04395). Information pertaining
to the installation of a power conditioner or voltage regulator/backup power supply may be
found in
“System Layout” on page 9 .
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
The Series 1000 System is capable of directly driving pump motors up to 3/4 HP at 115/230
VAC. A starter relay must be used with pump motors exceeding this limitation. 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
The Series 1000 System is capable of directly driving submersible pumps up to 3/4 HP at 115/
230 VAC. A dispenser with a submersible pump exceeding this limitation requires the use of a
submersible starter relay. A separate circuit breaker should be supplied for each dispenser in
cases where it will directly drive the submersible pump. 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
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 system’s
terminal blocks. The orientation of the chassis assembly is shown
Figure 4-1 on page 19 .
