To make the DC connections
Refer to Figure 3-8.
1. Cut the cables to the correct length with enough insulation stripped off so you
can properly install the type of terminals you will be using.
The terminals on the DC end are designed to fit up to 500MCM crimp-on ring
terminals (either AMP or ILSCO) or box connectors.
2. Attach the connectors to both cables.
If you are using crimp connectors, use the tool recommended by the terminal
manufacturer. Make sure no stray wire strands protrude from the terminals.
3. Route the DC supply cables from the battery bank to the PROsine.
4. Install a fuse and disconnect or breaker between the PROsine and the battery.
They must be installed in the positive side of the DC circuit, as close as
possible to the battery. This protects your battery and wiring in case of
accidental shorting. (See Table 3-2 on page 3–7 for required fuse size.)
5. Attach one connector on the positive cable to the positive DC terminal on the
DC end, and then attach the other connector to the POSITIVE (+) terminal on
the fuse or breaker.
Observe the polarities carefully while completing the installation. Use a
wrench to tighten to a torque of 216–240 inch-pounds (24–27Nm). Test that
the cable is secure.
6. Connect one connector on the negative cable to the negative terminal on the
DC end. Before proceeding, check that cable polarity is correct, and then
connect the other end of the cable to the NEGATIVE (–) terminal on the
battery.
This is the last cable connection you make. A spark is normal when it is made.
Use a wrench to tighten to a torque of 216–240 inch-pounds (24–27Nm). Test
that the cable is secure.
7. Attach the DC terminal covers. (See Figure 3-8.)
Important:
For residential installations, the installation code may require a DC wiring
enclosure for DC connections and cables. If you are using this accessory, secure it to the
PROsine before routing cables. Be sure to use crimp-on ring terminals on the PROsine end
of the DC cables (as specified on “Materials List” on page 1–6), and follow the installation
procedure provided with the wiring enclosure. Contact Xantrex or your distributor for this
part.
