AC INPUT FUSES
The input of each UPS module is protected by a 15A fuse for each phase, so that each module,
including the controller, has 3 fuses (for R, S, T phases). 10 modules plus the controller would
require 33 fuses, as illustrated in Figure
3-15. Fuse receptacles are numbered from right to left,
i.e. the 3 fuses on the far right protect UPS #1.
