Step 4: Installing the DC Switchgear and Connecting the DC Cables

DC Connection Precautions

Recommended

Cable Sizes and

Lengths and Fuse

Size

For recommended DC cables and fuse sizes, see Table 1-2 and Table 1-3 on

page 1–15.

Preparing the

Cables

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 of crimp connectors – The connector should have a 3/8" stud size to

connect to the Conext SW. If a crimp connector is used, it should be crimped

using the tool indicated by the connector manufacturer.

Attach the connectors to the ends of both cables. Make sure no stray wire

strands protrude from the connectors.

Guidelines for

Routing the DC

Cables

Follow these guidelines to ensure maximum performance.

• To reduce the chance of radio frequency interference, keep the positive and

negative cables close together—ideally, held together by straps, loom, or

insulated clamps at regular intervals.

• To ensure maximum performance from the inverter/charger, do not route your

DC cables through a DC distribution panel, battery isolator, or other device

that will cause additional voltage drops. The exception is the DC fuse and

Disconnect or the DC circuit breaker which is required at the battery to

protect the DC wiring.

• To help avoid damage caused by reverse polarity battery connection, it is a

good idea to mark each end of each cable to identify it as a positive (red) or

negative (black) cable before routing the wiring.

WARNING

ELECTRICAL SHOCK HAZARD

Connect and disconnect DC wiring only after opening and locking out the

disconnect switches or breakers at all AC and DC sources.

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

WARNING

ELECTRICAL SHOCK AND FIRE HAZARD

Route the cables away from sharp edges that can cut into or scrape the

insulation. Wires can become exposed. Avoid sharp bends in the cable.

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