3.2 Intrinsically safe sensors marked
1/2G Ex ia IIC T5/T6 Ga/Gb
Equipment in areas of category 1G requires:
 Where the sensor is mounted through a barrier wall to 1G,
(zone 0), ensure that the sensor mounting is sealed to at
least IP67 acc. to EN 60529.
 Connect the sensor housing to the earth point.
 Ensure that, at a current rating I
lowing criterion is met:
 Temperature class T6/T5 at a maximum ambient tempera-
ture of 50 °C / 70 °C (see section 1.3 Electrical specifica-
tion).
When using the sensor in connection with aggressive / corrosive
media:
 Test for material compatibility with the aggressive / corrosive
media.
3.3 Intrinsically safe sensors marked
2G Ex ia IIC T5/T6 Gb
 Ensure that, at a current rating I
lowing criterion is met:
 temperature class T6/T5 at a maximum ambient tempera-
ture of 50 °C / 70 °C (see section 1.3 Electrical specifica-
tion).
