7. Notes for mounting and operating in hazardous areas
T32.**.**9 (Use as non-incentive equipment II 3G EEx nA):
Disconnection of power supply is forbidden inside the hazardous
area. When connecting or disconnecting the terminals ensure the
power supply is disconnected outside the hazardous area.
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.
When during use in circuits with the safety class nA (non-incendive)
the permissible connected loads have been exceeded for a short
term
1) , the use of these transmitters in circuits with the safety class
EEx nL (energy limited) is not permissible any more.
1) When the transmitters are used in circuits with the safety class nA, it is permissible to exceed the maximum
supply voltage by up to 0 % for a short term.
Operation in Zone 0:
The temperature transmitter may only be operated in areas that
require apparatus of category 1 when following atmospheric condi-
tions exist:
Temperature: -20 °C ... +60 °C
Pressure:
0.8 bar ... 1.1 bar
Operation in Zone 1 and Zone 2:
According to the temperature class, these transmitters may be used
only in the following ambient temperature ranges:
