Figure 7-20: Wiring Diagram: 9852X, 9853X, 9840X, 9850AX, 9850AXS Dispensers
Diagrams shown are for Q Model pumps. If your pump is an A model, DC Junction box will be separate.
Notes:
1. The power resistor assembly is 8.2 kilo-ohm, 10 W (part number C05818) for 115/230 VAC domestic units and
30 kilo-ohm, 10 W (part number C06683) for 230 VAC International units.
2. Before applying power, the TopKAT Pump Control PCB jumpers must be set for electronic pulser as shown in
“Terminal Block ID” on page 42 . Failure to properly set the jumpers will damage the TopKAT.
3. The wire colors may vary. Refer to current pump wiring diagrams.
4. When multiple dispensers are used to control a common submersible starter relay or pump, and the 9800 is
controlled (authorized) through the Control/Subm Feed line (as in the case of some fuel management systems),
it is important that the lines from the 9800 to the submersible equipment be isolated from each other. This can
be accomplished by running the submersible control lines through a secondary set of relay contacts in the fuel
management system. If a secondary set of contacts is not available, external control relays must be used
between the 9800 and the submersible starter relay or pump. Another option is to provide a separate
submersible starter relay for each hose outlet. The submersible drive lines from the 9800 cannot be tied
together.
