NH2 Fuse Module Installation

WARNING: Hazardous energy levels are present on bare conductors in the -48Vdc distribution connection area of the plant. Accidental shorting of distribution conductors can cause arcing and high currents that can cause serious burns or other physical harm. It is recommended that:

Remove any jewelry, rings or watches while working on this equipment.

Use insulated wrenches, screwdrivers, cutters, pliers and other tools.

The NH2 Fuse Module requires one open module position. Insert the module in the power system such that the holes in the module dc bus line up with the holes in the power system
