Installing an External Power Source
LYNK II can utilize one of three power sources. LYNK II will automatically use the highest priority source if all three power sources are connected.
Connect LYNK II to one or more of the following:
A 13-92 VDC power supply (or battery) connected to the Phoenix connector pin 7 (GND) and pin 9 (Vin).
The AEbus Port or LYNK Port of a Discover lithium battery.
A USB device (relays will not function with USB as the only power supply).
