FUSES
There are no user replaceable components in the power supply.
WARNING!
Only properly trained and qualified personnel should remove the cover
from the power supply. Service, fuse verification, and connection of wiring
to the chassis must be accomplished at least
five minutes after power has
been removed via external means; all circuits and/or terminals to be
touched must be safety grounded to the chassis.
CAUTION!
To reduce the risk of fire or electrical shock, replace fuses only with the
same type and rating.
Internal fuses are listed in Table 5–2. Note, however, that failure of one of these
fuses indicates a more serious problem has occurred. Please contact the
factory for further assistance.
