Notes:
1. Secondary circuits of Class II apparatus which have connector terminals that could be earthed (e.g.
antenna signal input), are subjected to the requirements for circuits conductively connected to the mains in
Tables 8 and 9.
2. Floating secondary circuits of Class I apparatus which have connector terminals that could be earthed
(e.g. antenna signal input), are subjected to the requirements for circuits conductively connected to the
mains in Tables 8 and 9 unless the floating secondary circuit is separated from the primary circuits by an
earthed metal screen (e.g. in the power transformer), or the floating secondary circuit is connected to earth
via a component such as a capacitor.
3. For insufficient clearances and creepage distances from secondary to secondary circuits and from
secondary circuits to earth, see Cl. 4.3.1, 4.3.2 and 11.2.
4. If the minimum creepage distance in Table 11 is less than the minimum required clearance in Tables 8, 9
or 10 as required, then the value for clearance is used as the minimum creepage distance .
"Min" = minimum required.
