Feb 2013 1-7
a. Observe the position of the fuse block (shown on previous page) for reference. If the
single-fuse arrangement is desired, the fuse block should be positioned such that the
side with the single fuse slot and the jumper bar is away from the cover.
If the double-fuse arrangement is desired, the fuse block should be positioned such that
the side with the double fuse slots is away from the cover.
b. If the fuse block is positioned properly for the fusing desired, proceed to Step c.
If the fuse block is not positioned properly for the fusing desired:
1) Remove the fuse block retaining screw.
2) Lift the fuse block from the cover.
3) Rotate the fuse block.
4) Mount the fuse block to the cover.
5) Replace the retaining screw.
c. Insert appropriate fuse(s) for the input power source. Refer to the chart below for the
appropriate fuse rating.
7. Insert fuse block and cover assembly into input power connector and snap it into place.
Once the fuse block and cover assembly are in place, the position of the indicator pin
shows the input power selected.
The fuses used in the degasser must be identical in type and rating to that specified.
Use of other fuses could result in electrical shock and/or damage to the analyzer.
