Wiring
Recommended Wiring Practices
• Wiring or electrical harness must not rub on sharp edges.
•
The electrical harness should not be stressed at connections.
• The voltage drop between the battery and the pump should not exceed 5% of the rated battery voltage.
This should be verified at the pump’s maximum current draw.
•
Wiring or electrical harness must not rub or make contact with a hot surface. There should be 5" minimum
clearance from the exhaust.
• Wiring or electrical harness should be supported every 12–18 inches.
•
To avoid possible fire or shock, do not pinch any wiring or electrical harnesses.
Electrical Connections
The power input is a 12V or 24V DC (nominal) source depending on the component model. The ignition enable
is a switched power source which is sent from the vehicle or system to initiate operation of the component. This
can be wired directly to a vehicle ignition, to a PLC output, through a manual switch or through a thermal switch.
This line will draw less than 10 mA of current. All switches on this line can be sized based on this amperage
requirement. This input should be fused close to the source to protect the vehicle or system wiring.
