Recommended Wiring Practices
Warning: The CASCADE is designed for pilot-duty use and its outputs are for
control only. Wire the CASCADE controller with 18 gage stranded wire.
Important: For applications involving automatic start equipment, we strongly
recommend the installation of an appropriate Emergency Stop device.
1.
To help prevent electrical noise and voltage drop to the controller during cranking and preheat, wire
the controller DC power connections directly to the cranking battery. This will also help improve “Low
battery” starting capability.
2.
When using a battery charger, it should be connected directly to the battery to help prevent electrical
noise which could cause an engine ECU or associated equipment to operate erratically.
3.
Never route low voltage DC wiring in the same conduit as high voltage AC wiring. Noise from
electrical loads such as motors and variable frequency drives can be coupled into the engine ECU,
governor, or associated equipment and may cause erratic operation.
4.
Always use twisted shielded pair wires for the magnetic pickup wiring. Ground one end of the shield
only.
5.
In spark ignited engine applications, always use resistive spark plugs and spark plug wires, as these
greatly reduce the amount of radiated noise.
6.
Always place a snubbing diode (sometimes also called an anti-flyback, anti-kickback or reverse bias
diode) directly across any inductive load. This helps eliminate a common source of electrical noise, as
well as increases the operating lifetime of any solid state output.
7.
Always use twisted shielded pair communications wiring for RS-485, and SAE standard wire for
J1939. Make sure that terminating resistors (if required) have the correct rating and are installed
properly.
