Wiring Notes for Model 9820K – International ( Figure 3-4 on page 20 )
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) If the Pump Motor line is controlled by a fuel management system using solid state
relays, a resistor assembly must be installed between the Pump Motor Feed line and
Neutral to prevent false triggering of the authorization input. The resistor assembly is
30K Ohm, 10 Watt (P/N C06683) for 230 VAC international wiring.
3) Slow Flow and Fast Flow lines are typically used when connecting to an optional
valve. Each of these lines is capable of supplying 300 mA AC maximum (170 mA AC
maximum if already connected to the optional valve).
These lines must not be shorted to any conduit or chassis metal, incorrectly wired, or
connected to any equipment requiring more than stated maximum allowable current. If
these restrictions are not followed, damage to the CPU PCB will occur.

CAUTION
4) Use the wire size chart in “Wire Size” on page 11 to determine the wire size for the
control wiring.
