Truecharge 10TB Owner’s Manual

4.2 Mounting the Truecharge

Mount the Truecharge using four #8 (or M4) screws. Don’t skimp on either the number or type of screws. Damage resulting from insecure mounting is not covered under warranty. Mount on a vertical surface with the terminal block end below.

4.3 Connecting the DC Wiring

If the Truecharge will be charging two batteries, check that negative terminals of both batteries have a cable connecting them together, or individually to a common DC negative bus. The Truecharge cannot be used to charge a pair of batteries that are completely isolated from each other.

Warning: To prevent accidental short circuits, sparking, and possible battery explosion, damage or personal injury, all DC wiring from the Truecharge to the battery(s) must be completed prior to connecting AC wiring (see section 4.4).

Table 1 lists wire sizes required, and the ring terminal color code required to terminate the wires. Wire length shown is total length (combined length of negative and positive wires). When charging two batteries, use only the longest positive wire and the negative wire to arrive at the “Total Wire Length” in the table.

Table 1.

To avoid polarity errors and possible damage, never use wires of only one color. Use red insulated wire(s) for positive connection(s) and black insulated wire for the negative connection.

Follow these steps, and Figure 1, to connect the DC wiring to your battery(s). Wire sizes listed in the table above are absolute minimums. If there is any doubt, always use larger wire.
