Use the following procedure to connect the battery bank to the inverter.
To connect the battery bank to the inverter:
1. Determine the correct size battery cable to use for installation from Table 2-4
on page 2–8.
2. Determine the correct size disconnect/fuse for installation as per your local
electrical codes.
3. Identify the cables according to your local electrical codes. Ensure you
identify both ends of the cable prior to installation.
4. Connect the negative (–) cable to the battery’s negative terminal (torque to
manufacturer’s recommendations).
5. Install the over-current device (fuse or circuit breaker) between the battery’s
positive terminal and the inverter’s positive terminal. Place it as close to the
batteries as possible without being installed in the battery enclosure. Consult
your local electrical code for any distance requirements of the fuse from the
battery source.
6. Connect the (short) positive cable to the battery’s positive terminal (torque to
manufacturer’s recommendations).
7. Ensure the correct polarity of the cables with a DC voltmeter (DVM).
8. Observing battery polarity, connect the positive battery cable (from the
over-current device) to the inverter’s positive terminal.
9. Observing battery polarity, connect the negative battery cable to the inverter’s
negative terminal. See Figure 2-4 on page 2–6.
10. Use an insulated
½
in. wrench or socket to tighten the 5/16 SAE nuts to
10-15 ft.-lb (13.6 to 20.3 Nm) for each inverter input terminal.
11. Apply antioxidant paste to the battery and inverter terminals.

Ensure the inverter is off before connecting or disconnecting the battery cables and that all
AC power is disconnected from the inverter’s inputs.

The next step may cause a small spark and snapping sound when
connecting the cable to the inverter. This is normal and is caused by the inverter’s
capacitors charging up.

Do not put anything between the cable ring terminal and the flat metal part of the terminal
as overheating of the terminal may occur. Do not apply any type of antioxidant paste until
after the battery cable wiring is tightened.
