 Apparatus 
design 
Resistance to fire is achieved by a combination of 
engineering design, production methods and by using 
materials with low flammability for internal parts 
 
a) Exemption for components 
contained in an enclosure of material 
FV 0 to IEC 60 707 with openings 
not exceeding 1 mm in width

400 V (peak) a.c. or d.c. meets FV 1 
or better to IEC 60 707, unless used 
in a fire enclosure   
All PCB are of base material with flammability category   
FV 1 or better. See List of Critical Components.
