Notes:
1. All RTN pins are internally connected.
2. Meter function is to copy either of hall sensors.
3. Switch to 12V is active. Open switch is inactive.
Caution:
•
Do not apply power until you are certain the controller wiring is correct and has been
double checked. Wiring faults will damage the controller.
•
Ensure that the B- wiring is securely and properly connected before applying power.
•
The preferred connection of the system contactor or circuit breaker is in series with the B+
line.
•
All contactors or circuit breakers in the B+ line must have precharge resistors across their
contacts. Lack of even one of these precharge resistors may severely damage the controller
at switch-on.
