2.4.3.2 Temperature Transmitter Wiring

a. Cable connection to the temperature transmitter is made via the terminal
block (4) accessed by removing the terminal housing lid (2) (Figure 19) .
b. Ensure that the outer diameter of the selected cable is matched to an
EExe M20 cable gland (5). Unscrew the cable gland (5) and slide the cable
through the cable gland (5) and into the terminal housing (1) through the
cable entry (3).

HAZARDOUS AREA INFORMATION
The temperature transmitter is certifi ed intrinsically safe for
use in Hazardous areas by TRL and is covered by EC-Type
examination certifi cate TRAC09ATEX11232X. The instrument
conforms to the standards EN60079-0:2006, En60079-
11:2007, EN60079-26:2007, EN61241-0:2006, EN61241-
11:2006 certifi cation code II 1 G Ex ia IIC T4 Ga, Ex iaD 20
T135°C Da, Tamb -20°C to +85°C
Before using the temperature transmitter in any hazardous
environment, ensure that personnel are completely familiar
with the above standards relating to the certifi cation of this
instrument and also with the intrinsically safe apparatus
information in EN60079-14:1997 or equivalent codes of
practice in the country of installation.
If the temperature transmitter is not ordered together with
the analyzer, it is the user's responsibility to make sure
that the temperature transmitter is compatible with the I.S.
barrier in the control unit.
Refer to ATEX/CSA/IECEx certifi cates for the dew-point and
temperature transmitters' connection cable requirements
which stipulate maximum permissible mutual capacitance
and inductance to resistance ratio.
