Depending on the version, the explosion-protected surface-mounting
thermostat type ATH-EXx can be used as a
TW temperature monitor
TB temperature limiter
STW fail-safe temperature monitor
STB break-proof protection temperature limiter
in areas with an explosion hazard caused by gases, vapors or mists, Zone 1 or
in areas with combustible dust or dust/air mixtures, Zone 21.
If this surface-mounting thermostat is used inside the hazardous area, the
relevant regulations for mounting and operating equipment in such an area
must be observed.
Cutting through or kinking the capillary of the surface-mounting thermostat,
type ATH-EXx, will result in permanent failure of the instrument!
Only use the ATH-EXx with TZ 679 in areas that are classified as areas with
low mechanical risk.
