Maintenance

The CoreSense is maintenance-free, i.e., no regular maintenance is required. The fuse may require
replacement after an unusual voltage event.

Replacing the fuse

Use only the specified fuses: 1A/250V slow-blow (5×20 mm).
Simply replace the fuse in the fuse holder. See picture below for fuse holder location. To access the fuse
holder, remove the cover (see "Removing the cover" on page 20).
