6.2.1 Installation i 2G-/3G-enclosure
In order to guarantee the IP degree of enclosure protection = IP54 for installation in 2G
enclosures of Ex e type of protection (e.g. control equipment), and = IP6X for installation
in 2D enclosures in areas where combustible dusts exist - with “protection through the
enclosure” type of protection - the reinforcement frame should be used for fastening on
the front side.
A reinforcement frame is inserted between the retaining brackets and the enclosure
material for good transmission of the clamping force. This ensures even transmission of
force.
For POLARIS built into the enclosure door:
The open door must be supported and secured during the installation and servicing
phase. Otherwise the wall thickness specified may lead to the door sagging slightly
when open.
DANGER
If there is no reinforcement frame, it will not be possible to maintain the
IP protection. There is a risk of fatal injury in an explosive atmosphere!
Only use enclosure with at least 2 mm wall thickness.
Insert the reinforcement frame between the holder and the enclosure.
