024253 Wiring Diagram Model 9840Q
Notes:
1 All wiring and conduit runs must conform with all building/fire codes, all Federal, State, and
Local codes, National Electrical Code, (NFPA 70), NFPA 30, and Automotive and Marine
Service Station Code (NFPA 30A) codes and regulations. Canadian users must also comply
with the Canadian Electrical Code.
2 Pump motors must be wired as 230 VAC to reduce current draw (requires 230 VAC breaker
for control). If connected to equipment requiring control of the authorization input, the Phase 2
Feed should be switched through a separate relay to prevent false triggering of the
authorization signal.
3 To avoid damage to the CPU PC board, all unused wires must be individually capped, and
before applying power, you must verify that the RESET COMPLETE and FAST FLOW wires
are not shorted to conduit or chassis.
4 RESET COMPLETE (switch detect) line can supply 170 mA AC maximum for connecting to
fuel management system circuitry.
5 FAST FLOW line can supply 170 mA AC maximum for remote control or monitoring of the
fast flow valve found in the pump.
6 If the CONTROL/PUMP MOTOR FEED line is controlled by a fuel management system
using solid state relays, a resistor assembly must be installed between the Control Feed line
and Feed Neutral to prevent false triggering of the authorization input. The resistor assembly is
8.2K OHM, 10 Watt (P/N C05818) for 115/230 VAC domestic and 30K OHM, 10 Watt (P/N
C06683) for 230 VAC international wiring.
7 If this unit is equipped for 230 VAC operation (international) wire as shown in the standard
115 VAC wiring diagram. In this case, the white (WHT) motor wires should be connected to
the 230 VAC return wire (Feed Neutral). See breakaway version for international.
8 Use the wire size chart listed on page 5-4 when determining the wire size for the control
wiring.
9 Model 9840Q should not be used with aboveground tanks.
10 If this unit is equipped with a TopKAT option, there will be 10 wires in the junction box. See
The TopKAT Installation Manual for wiring requirements and information.
