10.5 Fuse Replacement
(1) To safely replace the fuse, shut off the external circuit breaker to stop the power supply to
the TDLS8000.
(2) Remove the fuse from the fuse holder. Using a flat-blade screwdriver that matches the
holder cap, turn the cap 90 degrees counterclockwise.
Then you will be able to remove the fuse with the cap.
(3) Check that the rating of the new fuse is correct, place it in the fuse cap, and insert the cap in
the holder. Using a flat-blade screwdriver, turn the cap 90 degrees clockwise while pressing
down.
Be careful because the fuse for the SCU is 3.15 A and that for the LU and YH8000 is 2.5 A.
(4) If the new fuse blows immediately, there may be a problem with the circuitry. Contact your
Yokogawa representative.
