WIRING INSTALLATION GUIDELINES
Danger: Never work on the engine while its power is on. This controller does
not generate a warning signal prior to automatic engine start. Warning signs should
be placed on engine equipment indicating this important safety measure.
INSTRUCTIONS
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).
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.
