4.1 Allgemeines
Der Temperaturregler dient innerhalb
von explosionsgefährdeten Bereichen zur
betriebsmässigen Temperaturregelung von
elektrischen Heizeinrichtungen.
Für den Einsatz ist zwingend eine Ex-i
Trennbarriere mit ATEX Bescheinigung
[Ex ia] IIC erforderlich.

4.1 General points
Temperature controllers are used for control-
ling the temperature of electric resistance
heaters in potentially explosive atmospheres.
The temperature controllers are designed for
stationary installation only.
