DANGER!

 

The classification for the device can be found on the EX-type plate on the unit. 

The device must only be used in the classification stated or in a lower classification.

 

 

2.6.2 

Surface temperature of the devices 

 

   

DANGER!

 

The temperature class mentioned on the EX-type plate on the unit must be observed, - make sure 
that the max. surface temperature is even fallen short of. 

 

 

   

DANGER!

 

The maximum surface temperature of the equipment must always be lower than the ignition 
temperature of the gas/vapour/dust/air mixture. Equipment which has been classified in higher 
temperature classes is, of course, also approved for use in applications with lower temperature 
classes. As gas/air mixtures for T5 do not occur with normal use, and only very rarely occur for T6, 
for specific gas/air mixtures such as carbon disulphide (IIC), our hoists are not rated for these 
temperature classes and must not be used for these classes.

EX zone classification 

Areas that are prone to explosion are classified into zones. The owner must determine the zone that exists. 
Information on the zone classification can be found in IEC 60079-10 and in national standards. The following 
table contains an overview of the zone classification in combination with the device category.
