Product Usage Instructions

To connect the power supply and the device to be powered, followthese steps:

1. Identify the 6 terminals for power connections.
2. Ensure that the power terminals are connected using AWG18wires.
3. Connect the positive connection from the Primary (Main) power supply to the red wire.
4. Connect the negative connection from the Primary (Main) power supply to the black wire.
5. Connect the positive connection to the device to be powered (Output) to the yellow wire.
6. Connect the negative connection to the device to be powered (Output) to the black wire.
7. The grey, green, and orange wires are used for optional voltage measurement of the two batteries.
8. Ensure that the gauge of the wires used for connections is18AWG for power terminals and 22AWG for voltage dividerterminals.

Refer to the designator table below for better understanding:

Designator| Main input| Main ground| Load| Battery positive| Battery negative| Voltage divider ground| Voltage divider main battery voltage| Voltage divider auxiliary battery voltage
---|---|---|---|---|---|---|---|---
