LED modules for 24 V intrinsic safety (floor mounting)
The LED modules for enclosure mounting are installed in 3SU18 enclosures. The LED
modules are approved in accordance with IEC 60079-11 and are used in hazardous zones
1, 2. They comply with the "ib" type of protection for intrinsic safety.
On enclosures with raised cover (Article No.: 3SU180(5)1-1AA00-0AA1) base mounting is
not envisaged.
You will find additional information in Chapters "ATEX for intrinsically safe circuits
(Page 25)", "3SU18 enclosures (Page 219)".
