Notes:
1. All RTN pins are internally connected.
2. Kelly Ammeter positive connect to 5V power supply of controller, negative to Dark
Blue wire.
3. Switch to ground 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.
