6. Notes for mounting and operating in hazardous areas
6.3.2 Sensor (terminal 1 to 3)
The connected sensor must not warm up inadmissably according to
the temperature class of the respective hazardous area for the
following values for voltage, current and power:
Model T24.10.**2
II 1G EEx ia
Model T24.10.**9
II 3G EEx nL/nA
The sum of the values of the connected sensor and the connection
line must not exceed the following values for the maximum
permissible capacitance and inductance:
Mod. T24.10.**2 II 1G EEx ia Group IIB
Mod. T24.10.**2 II 1G EEx ia Group IIC
Mod. T24.10.**9 II 3G EEx nL/nA
