Integrity of fuses can be checked with a multi-meter without removing the boards from the enclosure.

Figure 5 - Fuse Test Points

To replace fuses it is recommended that the electronics assembly is removed from the enclosure in the
manner described in the preceding section.

Once removed, release the field IO board from the main board by removing the 4 screws and PCB
standoffs located in the corners of the board. Carefully rotate the field IO board forwards to access the
fuses. Replace with radial board mount fuses of equivalent rating. Reinstall the electronics assembly
before powering up.
