NOTE
DC Input Wiring (Starter)
The DC-DC input will connect to the 12V starter battery that will be used to charge your auxilia-
ry or house battery. The starter battery may be a different chemistry from the house battery.
The DC-DC input and output terminals are isolated, meaning that the output voltage can be
kept stable without interference from the input circuit. This ensures stable and correct charging
of auxiliary batteries.
1.Use a screwdriver to loosen the DC input terminals by rotating counterclockwise (CCW)
2.Connect a ring terminal cable from Starter Battery Positive to the Positive DC Input Terminal
3.Use a screwdriver to tighten the DC Input terminal by rotating clockwise (CW)
4.Repeat for the Starter Battery Negative to the Negative DC Input Terminal
The DC-DC will not power on or operate until the D+ ignition cable is connected.
When connecting the DC input, note that the DC-DC will still be off until the D+
ignition cable voltage senses.
