Normative DIN (German) uses the first letter U mean (or) V, W (electrical machinery) and (R) (S) (T) for electrical terminal phases of 120°. (The ease of doing it this way will vary by furnace and installation.) Look for a row of screws labeled R, C, W, W2, G, Y/Y2, like so. Disable power to your furnace and pop the cover off. Now, use for start or wey connection single voltageįor start connection join (X, Y, Z) and connect U (phase 1), V (phase2), W (phase3) and delta join (U, Z) phase 1, join (V,X) phase 2, join (W,Y) phase 3. Method 2: Look at the wires inside your furnace. Phase 2 is similar to phase 1, V head start - Y end head. The first head nest start letter U - (end nest) (one pole north) join end - X terminal (one pole south) phase 1 north pole and south pole 180° elec grade. In normative DIN use for terminal leads the letters U, V, W signify the coil head, and letters X, Y, Z signify coil end.įor example, a two pole three phase motor has 6 nests, 3 coils per nest, and 6 leads. In normative for manufacture electrical motors there exist two standards: DIN convention (Europe) and NEMA (American countries).
