General information

The standard empty enclosures and connecting flanges from the EX – Line series are made of stainless steel pursuant to EN 10088. The enclosure and the doors are produced as a rectangular welded construction made from stainless steel sheet 1.4301 which is at least 1.25 mm thick or higher, depending on the size and design.

In addition to using closures, the doors can also be screwed in place using multi-purpose nuts which are welded on outside the seal area.

Drill holes and recesses can be introduced in the door, in the rear wall, in the base and in the side walls. These are used to accommodate cable and lead feed-ins only in the mandatory protection classes. The flange plates are produced from stainless steel plate which is at least 2.0 mm thick. These are then screwed to the enclosure using EPDM – moulded seals.

Closure IP66

• Welded multi-purpose nuts 
• Screwed using countersunk screws and conical feed-ins which are attached outside the seal area 

Wall mounting

• The enclosure can be mounted using external wall brackets which are secured against rotation. Alternatively, the locking nuts in the enclosure can be used.

Labelling

• A self-adhesive identification plate made from corrosion and heat-proof material is attached to the enclosure for identification.
• The identification plate carries the information required by EN 60079-0:2012.
