The aforementioned Slam® Trans–types are certified as follows. You may find brief
explanation of certificate beneath:
CE
II 2 GD
0537
CE
= Valid production quality system approved and notified by VTT (Finnish Notified Body,
0537
listed by EC)
= Certified for explosion-hazardous areas
II = Certified for use in areas excluding mines
2 = Equipment category (suitable for Zone 1&21 and Zone 2&22)
G = Certification taking account explosion hazardous GASES
D = Certification taking account explosion hazardous DUSTS
Explanation of marking for explosion hazardous area due to Gases (Ex e mb IIC T4 Gb):
Ex = Certified for use in explosion hazardous areas
e = Explosion protection method increased safety (of certain components)
mb = Explosion protection method encapsulation (encapsulating ignition sources e.g. Ex-
fuse)
IIC = Equipment group (for all IIA, IIB and IIC gases)
T4 = Maximum inside temperature of the unit is 135 °C (within the ambient temperature range
of
-20°C - +40°C)
Gb = Explosion Protection Level (EPL) marking for "HIGH" level of protection. Equipment for
explosive GAS atmospheres, which is not a source of ignition in normal operation or during
expected malfunctions
Explanation of marking for explosion hazardous area due to Dusts (Ex t IIIC T 70 °C Db):
Ex = Certified for use in explosion hazardous areas
t = Explosion protection method "protection by enclosure"
IIIC = Equipment group for conductive dusts (including IIIA, IIIB and IIIC dusts)
T 70 °C = Maximum OUTSIDE surface temperature of the unit is 70 °C (within the ambient
temperature range of -20°C - +50°C)
