Wiring Ignition Signal
To have ignition power control for in-vehicle usage, you need to supply IGN signal to the
system. The IGN input is located on the 3-pin pluggable terminal block (shared with DC
power input). Below is the typical wiring configuration for in-vehicle applications.
1.
Connect car line (12V for sedan, 24V for bus/truck) to V+.
2.
Connect car Batter-/ GND line to GND.
3.
Connect ACC line to IGN.
WARNING
Please make sure your DC power source and IGN signal share the same ground.
IGN input accepts 8~35VDC. Supply a voltage higher than 35VDC may damage the system.
