The LC Video Screen Series user manual up to and including Revision C stated that each of the three power supply units in the base of an LC 2140 panel has a 10 amp main fuse. This was incorrect. LC 2140 panels use the same 5 amp main fuses as LC 1140 panels. If one of the 5 amp main fuses in the base of an LC 2140 panel blows, replace it with a 5 amp fuse.
The LC Series user manual Revision D and later contains correct fuse details.
