CAUTIONARY NOTE: 

In common with all other electrical apparatus installed in hazardous areas,this apparatus must 
only be installed, operated and maintained by competent personnel. Such personnel shall have 
undergone training, which included instruction on the various types of protection and installation 
practices, the relevant rules and regulations, and on the general principles of area classification. 
Appropriate refresher training shall be given on a regular basis. [See clause 4.2 of EN 60079-17].
This instruction manual supplements the requirements of nationally accepted codes of practice,
