Special conditions for safe use:

Œ

When the equipment is installed, particular precautions must be take to ensure, taking into account the effect of the process tempera-

ture, that the ambient temperature of the electrical parts is between -40° and +70° C.



When the material is equipped with a aluminum enclosure, all precautions shall be taken to avoid all impacts or frictions which can

result in the ignition of the potentially explosive atmosphere.
