10.9.3 Replacing Panel-Mounted Fuses
CAUTION! This procedure should only be performed by a trained service technician.
To remove and replace the panel mounted fuses:
1. Perform a service shutdown as described in 6.9.2.4 Service Shutdown.
WARNING! Make sure that all electrical and pneumatic power supplies have been turned off
and disconnected as described in 6.9.2.4 Service Shutdown. Failure to do so
may cause serious injury or death.
2. Determine which fuse needs to be replaced.
3. Use the small flat head screwdriver to turn the fuse cap one-quarter turn counterclockwise.
Gently push the fuse cap inward while turning it. See Figure 10-6.
! The fuse cap will pop out enough to allow you to grasp it with your fingers.
4. Pull the fuse out of its socket.
5. Remove the damaged fuse from the fuse cap and replace it with the proper replacement fuse.
CAUTION! Always replace the fuse with a fuse of identical rating and size. Failure to do so
will not protect components from damage and may cause fire.
6. Gently push the new fuse into the socket until the head of the fuse cap is flush with the
socket rim.
7. Push in and turn the fuse cap clockwise one-quarter turn using the small flat head
screwdriver.
8. Perform a system startup as described in the 6.9.1 Startup.
