Electrical connection in explosion hazardous areas

The TE2 with Pt100 output can be used in explosion hazardous areas of zone 0, zone 1 and zone 2.
DANGER
Risk of fatal accident due to a wrongly connected sensor
Correct gas protection can only be achieved by meeting their installation requirements.
Make sure that all requirements are met and that sensor and installation have a valid approval
f „
for their specific explosive atmosphere.
In explosive gas atmospheres of zone 0, zone 1 or zone 2, use Zener barriers.
f „
Allow only persons trained in explosion protection to perform the installation.
