Fuses
There are seven fuses on the Katana
752i circuit board.
Note:
The part numbers for these fuses are subject to change. Please check with Emerson before ordering replace-
ment fuses.
ment fuses.
F1—F2:
These 1-amp fuses (see
) protect the ±12-volt power supplies. They are Emerson part
number 02739005-00.
F3—F4:
) protect the 3.3-volt and 5-
volt power supplies. They are Emerson part number 02959021-00.
F5—F7:
) protect the power supplies for the COP/JTAG interface
(P3) and PLD header (J7). They are Emerson part number 02959012-00.
