3.3 SERVO DRIVER & SDIST FUSES
1. Turn the main switch (upper right of electrical cabinet) to the off position.
2. Using a large flat tip screwdriver, loosen the three screws on the cabinet door and then open the door enough to safely
work on the electrical panel. Wait until at least the red CHARGE light on the servo drive assembly goes out before
beginning any work inside the electrical cabinet.
3. On the SERVO DRIVE ASSEMBLY, there are three fuses on the SDIST panel, and three individual fuses on each of the
SERVO DRIVE boards (See Fig. 3-4; the F3 fuses are not shown).
4. On the SDIST panel, use a flat tip screwdriver to turn the fuse(s) counterclockwise to remove. Replace the blown fuse(s)
with ones having the same type and rating (FU1, FU2: ½ amp, type AGC, 250V; FU3: 5 amp, type ABC, 250V).
5. On each of the SERVO DRIVER boards, the fuses (F1, F2, F3) may be replaced by simply pulling out the fuses by hand
and replacing with fuses of the same type and rating (F1, F2: 20 amp, type ABC, 250V; F3: 10 amp, type ABC, 250V).
