2. Wiring Installation Guidelines
Danger: The controller does not generate a warning prior to Automatic Engine
start. Do not work on the Engine while power is applied to the unit. It is highly
recommended that warning signs be placed on Engine equipment indicating the
above.
Following these instructions will help avoid common installation problems during wiring and
setup.
• Battery must be disconnected before any wiring connections are made.
Wire length from the engine to the controller should not exceed 6 meters (20 feet).
2.1 Wire Sizing
Wiring size and type should be as specified below. Use stranded wire, since solid wire has a
tendency to crack, break and loosen over time.
