materials or sealing grease in particular on the processed sealing surfaces of
the covers of terminal boxes having the following degree of protection:
"pressure-resistant encapsulation, EEx d IIC(B) marking".
The approved sealing materials are:
• For threads and surfaces:

In the case of "increased safety" terminal boxes the gaskets
used are included in the approval. Only original gaskets are
to be used.
