Appendix A – Internal links and fuses
Fuses (Mains Inlet)
The mains inlet contains a single 1 amp 1.25" time delay fuse (SSL Part No. 35FJJ310). To change it disconnect the
mains inlet, then using a small screwdriver prise open the mains selector cover. This contains the fuse. Test and
replace with the same type and value if necessary.

The internal power rails are also individually fused. These fuses should only be changed by suitably experienced
staff. They are listed below
