- Next, install the fuse holders FH1–FH8. Begin by placing each one in their respective holes. The fuse holders are non-polarized, which means that they may be installed in either direction.
- Flip the entire assembly over and solder them in place.
The fuse holders should be a friction-fit in their holes – this will help to hold them in position as you flip the board over and solder them. If they’re a looser fit, you can simply place a piece of tape across the tops of the holders to maintain their position when flipped upside down.
All of the fuse holders should be tight to the board when they’re properly soldered.
