11.2 Designs for potentially explosive atmospheres in accordance with ATEX and FM

This chapter includes information that must be observed when using the devices in potentially
explosive atmospheres (devices in accordance with ATEX Cat. 1/2 G and 2 D (Zone 1/21, Zone
0/21), FM Cl.1, Div.1/2).
This applies specifically to the mandatory safety instructions, the wiring of the signal and supply
power lines, and the safety specifications from the valid certificates.
Please also remember to comply with the other information in this manual.
Information for safe operation
ATEX
Meters must be installed, commissioned and operated according to ElexV (Standard on
electrical equipment in potentially explosive atmospheres) and EN 60079-14 (Installation of
electrical equipment in potentially explosive atmospheres).
FM
Installations must conform to "Installation of Intrinsically Safe Systems for Hazardous
(Classified) Locations" (ANSI / ISA RP 12.6) and "National Electric Code" (ANSI / NFPA 70
Sections 504 and 505). Comply with the relevant control drawings.
