Installing the TS400
975-0055-01-01 2–17
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 2–9
for 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 TS400 Sine Wave Inverter.
11. Use a wrench to tighten the nut to a torque of 2.2–2.6 lbf-ft
(3.0–3.5 Nm). Test that the cable is secure.
