in talation cor esp n s to the con ition for SELV or PELV

For protection again t direct contact the f olowin protective me s res a ply:

- protection by b r iers or en los res;

- protection by o stacles

(se IEC 6 3 4-4-41,412.1 to 412.3)

For protection again t in irect contact the f ol owin me s res can b selected:

- protection by automatic dis on ection or sig al n ;

- protection by protective in ulation;
