Notes:
1. All GND pins are internally connected.
2. Twist peripheral wires with PWR is the preferred for EMC.
3. Kelly Ammeter positive connect to 5V power supply of controller, negative to pin8.
4. 12V only can be used for Switch or LED wiring, such as 12V brake switch(pin 25).
5. The current meter is installed between pin4 and pin8.Pin4 is going to positive of
current meter,Pin8 is going to negative of current meter.
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.
