SYSTEM AND PUMP/DISPENSER WIRING
System/Peripheral Equipment: AC Power for the system
components 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 CFN system
components, terminal, and modem. However, it is acceptable to
supply the power to different CFN system components and
accessories from multiple breakers within the same panel and
the same phase of power. If necessary, the terminal or modem
may be on a different separate, dedicated breaker.
Power: 120 VAC + 10% 47-63 HZ.
Power conditioner: Optional.
Grounding: All system grounds must return to the same breaker
panel to ensure a common ground and protect the RS-485 data
loop circuitry.
Pulsers: Reed (contact closure) type pulsers require two wires
per pulser. Electronic pulsers require three wires per pulser.
See Pulser Wiring later in this document.
SUCTION PUMPS
The CFN pump control unit is capable of directly driving pump
motors up to 3/4 HP at 120/240 VAC or 1-1/2 HP at 240 VAC.
A starter relay must be used with pump motors exceeding these
limitations. 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.
9800A ELECTRONIC PUMPS
Series 9800A electronic pumps do not use the CFN pump
control unit; they are wired as independent units. See the 9800A
Installation Manual, 035296 for details.
DISPENSERS
The CFN pump control unit can directly drive submersible
pumps up to 3/4 HP at 120/240 VAC or 1-1/2 HP at 240 VAC.
A submersible starter relay must be used with pump motors
exceeding these limitations. A separate circuit breaker is
required for each dispenser directly driving a submersible pump.
Dispensers may be grouped together on a single breaker when
the submersible pump has its own breaker. No more than two
dispensers should be powered from one breaker to allow
isolated control with the circuit breaker panel in case of
problems.
