Xantrex Technology 3000 manual Connecting the DC Cables

Connecting the DC Cables

6.Connect one connector on the negative cable to the negative terminal on the DC end. Before proceeding, check that cable polarity is correct, and then connect the other end of the cable to the NEGATIVE (–) terminal on the battery.

This is the last cable connection you make. If the disconnect switch or breaker is not turned off, a spark is normal when the connection is made. Use a wrench to tighten to a torque of 216–240 inch-pounds (24–27 Nm). Test that the cable is secure.

7.Attach the DC terminal covers.

8.Before proceeding, double check that you have connected the cables properly—positive to positive, negative to negative.

9.Turn on the battery disconnect switch or breaker.

10.If you have installed a battery selector switch, use it to select one of the batteries or battery banks (house bank preferred over start bank).

11.Move the inverter’s On/Off switch to the On position.

12.Check the input voltage display. It should read between 12 and 13 V, depending on the condition of the battery. If it does not, check your battery and the connection to the inverter, and the state of charge of the battery.
