NOTICE
Possible damages of the facility!
At insufficient dimensioning of the wire cross-section the respective line may
be excessive charged. This leads to strong heating of the conductor up to
damage.
The wire cross-section has to be dimensioned according to the nominal current
of the selected fuse and the expected load current.

When using fuse-links of the type Little fuse TF90 – 15 A (delivery condition) and considering the maximum
permitted continuous current at the input terminals, see chapter 5.3. For selection of the correct fuses see chap-
ter 9 “Order Designations”.
