Connecting the DC Cables
Consult Figure 3-1 on page 3–2, “Configuration for Normal Loads” or
Figure 3-2 on page 3–3, “Configuration for Heavy Loads” for additional
details that are specific to your installation.
To connect the DC cables:
1. Make sure the inverter’s On/Off switch is in the Off position.
2. Strip 1/2 inch (13 mm) to 3/4 inch (19 mm) insulation from one end of
each cable. The amount stripped off will depend on the terminals
chosen.
3. Attach the connectors that will join the cables to the battery, battery
isolator switch, or fuse block. The connectors you use must create a
permanent, low-resistance connection.
If you are using crimp connectors, use the tool recommended by the
terminal manufacturer. Make sure no stray wires protrude from the
terminal. (You may find it more convenient to have the crimp
connectors attached by the company that sells you the cable and/or
connectors.)
4. For each cable end that will be connected to the inverter, strip 1/2 inch
(13 mm) to 3/4 inch (19 mm) of insulation from the cable. The amount
stripped off will depend on the terminals chosen.
5. Attach the connector that will join the cable to the DC cabling terminal.
6. Install a fuse and fuse holder in the cable that will be used for the
positive side of the DC circuit.
The fuse must be:
• as close to the battery as possible
• rated for DC circuits
• have an Ampere Interrupting Capacity (AIC) that exceeds the short-
circuit current available from the battery. (See “Calculating Fuse/
Circuit Breaker Size” on page 3–12.)
7. If you have installed a battery selector switch, set it to Off when making
the connection to prevent sparking.
8. Attach the connector on the positive cable to the positive DC terminal
on the inverter.
