AC Power-line Fuses
This section gives step-by-step instructions for changing the AC power-line fuses in your EIS Box. Please follow
these instructions carefully. You need a small flat-blade screwdriver to perform this procedure.
1.
Unplug the AC power line cord from the back of the EIS Box. The fuses cannot be changed with the AC
line cord plugged into the EIS Box.
2. Find the AC input module on the left side of the EIS Box’s rear panel. It can be identified by the line-cord
connector built into it.
3. Find the small slot on the right side of the AC input module near the line-voltage setting window. Place the
blade of a small screwdriver in this slot and pry open the AC input module.
4. The fuses are contained inside two fuse holders. The tops of the fuse holders are black plastic with a white
arrow on them.
Use the screwdriver to gently pry up the plastic portion of the fuse holders. After the fuse holders are up
about 1 cm you should be able to grab them with your fingers and pull them completely out of the AC
input module.
5. Remove the old fuses by prying them out of the fuse holders. Replace them with the correct fuses, which
simply pop into the fuse holders. The fuse orientation in the fuse holder is unimportant.
