HPR260XD Transformer Wiring 5. From the new wire group, use the two short wires to connect C4 to B1 and B4 to A1. Use one piece of 75 mm (1 inch) heatshrink tubing (104423) on each connection. 6. Use the long wire to connect C1 to A4. Use one piece of 75 mm (1 inch) heatshrink tubing (104423) on each connection.

HPR260 and HPR260XD Transformer Wiring 3. Discard the wires that connect C3 to B1 and B3 to A1. See Figure 5. Figure 5 From main contactor Discard C3 to B1 and B3 to A1 From main contactor 4. Reuse the wires that wire connect C1 to C3, C2 to C4, B1 to B3, B2 to B4, A1 to A3, and A2 to A4 and install them on the new transformer.
