2.4.4. Explosion groups
Flammable gases and vapors are classified according to explosion
groups (I, IIA, IIB and IIC) and temperature classes. Tab. 5 (ca-
pacitor motor) and Tab. 6 (3-phase motor) show the classification
of the most common flammable gases and vapors.

Tab. 6
The motor may only be operated in an environment which contains
an atmosphere which is not explosive or belongs to the explosion
groups II A, II B or II C and the temperature class T3 or below (ca-
pacitor motor; marked range in Tab. 5) or T4 or below (3-phase
motor; marked range in Tab. 6).
