Check that the power fuses are securely bolted and torqued in place.
Torque value is 20 Nm [15 ft-lbs]. Check that the electrical wires are
attached to both ends of the fuses. Make sure the fuses are not blown. The
red indicator pin should be flush with the top of the fuse. See Figure 6-11.
If one fuse has blown, the other fuses may be degraded. ABB
recommends that all fuses be replaced.
