3.7 Fuse Rating
The XN3 is fitted with a single resettable fuse on the Live circuit, of either 750mA
for AC input units or 2.5A for DC input.
If there is a power fault, the fuse may activate in which case power should be
removed from the unit and reapplied.
3.8 External Overcurrent Protection
The XN3 should be installed on a circuit with a double-pole circuit breaker of a
maximum rating of 25A. This is the maximum current rating of the smallest
internal chassis earth bond in accordance with EN60950-1 2.6.3.3. Refer to
Extronics if it becomes necessary to exceed this rating.
