4.3 Fuse Replacement
There are four fuses installed in the galvanic isolator module for
circuit protection. The main fuse (F1) is accessible after removing the fuse
holder cover. All other fuses require separating the 2 galvanic isolator
modules. See Figure 4-2 for fuse identification. Table 4-1 lists the fuse
rating, TAI part number, and the applicable circuit it serves to protect.
