1. Run 2 (or 3) wires from the Truecharge to the battery(s), and fasten
neatly along their length. Do not connect wires yet. For a single battery
system, use one black wire for the negative connection and one red
wire for the positive connection. For a two battery system, add a second
red wire. Follow local code(s) regarding the use of conduit, wire loom
or other wiring protection.
2. Insert both wire clamps supplied into the two holes in the lower end of
the Truecharge and tighten their locknuts securely. Only one wire clamp
will be used for DC wiring, and the other will be used later in step 4.4 to
clamp the AC wiring.
3. Insert the DC wires through the left hand wire clamp and trim the wires
so about 6" (15 cm) of length protrudes inside the Truecharge wiring
compartment.
4. Strip 5/16" (8 mm) of insulation from wire ends, and crimp a ring terminal
to each wire using the correct crimping tool recommended by the crimp
terminal manufacturer. Use the correct size (color code) of ring terminal
specified in Table 1.
5. Remove the 3 unused terminal block screws in the “DC Output”
compartment. Using these screws, fasten the ring terminal attached to
the black wire to the (-) terminal, and the ring terminal attached to the
red wire to either of the (+) terminals. For a two-battery system, connect
the second red wire to the unused (+) terminal. Terminal screws must
be fully tight. For a single battery system, one of the two (+) terminals
will be unused.
6. Tighten the wire clamp firmly around the wires.
7. Xantrex recommends, and most local installation codes require,
installation of a DC fuse connected to the positive battery terminal of
each battery. Fuse size must not exceed 15 amps.
8. Using suitable battery terminal post connectors (typically, ring terminals
connected through the battery terminal’s clamp bolt), first connect the
red wire to the positive (+) battery post. As a last step, connect the
black wire to the negative (-) battery post. If two batteries are being
connected, connect one red wire to one battery’s (+) post (or battery
fuse, if installed in step 7), and the second red wire to the second
battery’s (+) post (or battery fuse). It doesn’t matter which wire is
connected to which battery. As a last step, connect the black wire to
the nearest negative battery post.
Caution: Battery connections must be made direct to the battery(s) or
to the battery fuses (if installed), and must never be made to a DC
distribution panel or to a battery isolator or similar device.
