Connecting the DC Cables
Consult Figure 3-1, “Configuration for Normal Loads” on page 3–2 , or
Figure 3-2, “Configuration for Heavy Loads” on page 3–3 , 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
• be rated for DC circuits
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.
9. Install the lock washer and nut that are supplied with the inverter.
Tighten the nut to a torque of 11–13 foot pounds (16–18 Nm). Make
the connection snug enough so the ring terminal does not move
around on the DC terminal, but do not overtighten. See
Figure 3-3,
“DC Panel Connections (XPower 1750 Plus shown)” on page 3–14 .
