7.2 Special conditions for safe application
T32.30.***:
The surface of the case is not conductive. The temperature trans-
mitter must be mounted in a way that electrostatic charges will not
occur.
T32.**.**2:
Transmitters in a hazardous area are supplied only with associated
intrinsically safe apparatus that are approved for this hazardous area.
These transmitters must be mounted in a case that must at least
correspond to following ingress protection IP 20 per DIN EN 60 29 /
IEC 29.
T32.1*.**2 for category II 1G/IIC in addition:
The surface of the case is not conductive. The temperature transmitter
must be mounted in a way that electrostatic charges will not occur.
T32.**.**9 (Use as energy-limited equipment II 3G EEx nL):
The supply current circuit must fulfil the requirements for ignition
protection type II 3G EEx nL, energy-limited. These transmitters
must be mounted in a case that must at least correspond to
following ingress protection IP  per DIN EN 60 29 / IEC 29.
