Installing the Inverter/Charger

Step 4: Connecting the DC Cables

DC Connection Precautions

ELECTRICAL SHOCK HAZARD

Connect and disconnect DC wiring only after opening the disconnect switches or breakers at all AC and DC sources.

Failure to follow these instructions will result in death or serious injury.

Recommended Cable Sizes and Lengths and Fuse Size

For recommended DC cables and fuse sizes, see Table 2 and Table 3 on page 14.

Preparing the Cables

To prepare the DC cables:

1.Cut the negative and positive cables to the required length. Strip off enough insulation so you can install the terminals you will be using.

Use crimp connectors. The connector should be designed for a

9.5mm stud size to connect to the Freedom SW 230V. If a crimp connector is used, it should be crimped using the tool indicated by the connector manufacturer.

2.Cut the DC ground cable to the required length. Strip off enough insulation so you can install the terminals you will be using.

Use crimp connectors. The connector should be designed for a

6.35mm stud size to connect to the Freedom SW 230V. If a crimp connector is used, it should be crimped using the tool indicated by the connector manufacturer.

3.Attach the connectors to the ends of both cables. Make sure no stray wire strands protrude from the connectors.
