DPP system fuses

DPP fuses are located on the front panel of the DPP power supply.
The power supply has the –48 V dc circuit fused. A GMT–type fuse is used.
These fuses have a spring–loaded colored flag which opens when the fuse is
blown. To replace, pull the blown fuse straight out from the fuse holder and
insert the new fuse of the same type and rating.
A clear fuse cover is furnished for covering the fuse as a safety precaution.
After performing fuse replacement, remember to install the cover.
