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.

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). Motor environment
