Xantrex Technology XS400 manual To connect the DC cables

Installing the XS400

To connect the DC cables:

Connect the DC cables as shown in Figure 2-5,in the order shown by the numbers.

1.Switch the On/Standby switch to the Standby () position.

2.Route the DC cables from the battery bank to the inverter. See “Step 6: Routing the DC Cables” on page 2–15.

3.Install a DC fuse and Disconnect or a DC circuit breaker in the positive side of the circuit within 18 inches of the battery.

This protects your battery and wiring in case of accidental shorting. (See “DC Fuse and Disconnect or DC Circuit Breaker” on page 2–9for recommended fuse size and type.) Open the DC fuse and Disconnect or turn off the DC circuit breaker.

4.Connect one connector on the POSITIVE (+) cable to the POSITIVE DC terminal on the inverter. Tighten the nut to a torque of

2.2–2.6 lbf-ft (3.0–3.5 Nm).

5.Connect the other connector to the positive (+) terminal DC fuse and Disconnect or to the DC circuit breaker. Use a wrench to tighten the connection according to the manufacturer’s recommendations. Test that the cable is secure.

6.Attach a short DC cable from the unconnected end of the DC fuse and Disconnect or DC circuit breaker. Tighten appropriately.

7.Observing polarity carefully, connect the other end of the fused cable to the POSITIVE (+) terminal of the battery. Tighten this connection to the battery manufacturer’s recommended torque.

8.Connect one connector on the NEGATIVE (–) cable to the NEGATIVE (–) battery terminal. Tighten the connection according to the battery manufacturer’s recommended torque.

9.Check that the polarity of the DC connections is correct: positive (+) on the inverter is connected to the positive (+) on the battery, and negative (–) is connected to the negative (–).

10.Connect the other connector of the NEGATIVE (–) cable onto the NEGATIVE (–) terminal on the XS400 Sine Wave Inverter.

11.Use a wrench to tighten the nut to a torque of 2.2–2.6lbf-ft(3.0–3.5 Nm). Test that the cable is secure.
