This symbol documents the declaration of the
manufacturer that the required EC-guidelines – as stated
in the EC-Declaration of Conformity - are observed and its
provisions are followed.
This air motor is suited for standard use in
Ex-areas.
Design Group: this motor is NOT designed for use in
underground mining.
Design Category: this motor is designed for the use in
areas where occasionally explosive atmospheres may
exist, which consist of gases, steam, combustible fumes
or a combination of dust and air (Zone 1 and Zone 21).
This motor is suited for the use in Ex areas, which are
caused by combustible gases, steams, fumes or dust.
Ignition Protection: structural protection
Explosion Group: This motor is suited for the requirements
per Explosion Group IIC. It also fulfills the requirements of
the Explosion Groups IIB and IIA.
Temperature Class:
T6 = 85°C surface temperature
A motor with a temperature class of T6 may not exceed a
maximum surface temperature of 85°C. Motor should be
tested to ensure that the permissible temperature does not
exceed 80°C; there is a safety margin of 5°C.
This is the maximum permissible surface temperature of
the motor if used in an explosive atmosphere containing
dust.
Temperature Class:
T5 = 100°C surface temperature
A motor with a temperature class of T5 may not exceed a
maximum surface temperature of 100°C. Motor should be
tested to ensure that the permissible temperature does not
exceed 95°C; there is a safety margin of 5°C.
This is the maximum permissible surface temperature of
the motor if used in an explosive atmosphere containing
dust.
Temperature Class:
T4 = 135°C surface temperature
A motor with a temperature class of T4 may not exceed a
maximum surface temperature of 135°C. Motor should be
tested to ensure that the permissible temperature does not
exceed 130°C; there is a safety margin of 5°C.
This is the maximum permissible surface temperature of
the motor if used in an explosive atmosphere containing
dust.
