with the liquid level, it raises the attraction sleeve
into the field of the magnet, which then snaps against
the non-magnetic enclosing tube

IEC Installation Instructions:
Controls with two or more HS or H1 switches are not ATEX approved.
The cable entry and closing devices shall be Ex d certified suitable for the conditions of use and correctly installed.
For ambient temperatures above +55° C or for process temperatures above +150° C, suitable heat resistant cables shall be used.
Heat extensions (between process connection and housing) shall never be insulated.
Special conditions for safe use:
When the equipment is installed in process temperatures higher than +85° C the temperature classification must be reduced
according to the following table as per IEC60079-0.
