3.0 Installation of the EX-5165
C
AUTION
:
Area must be declassified during installation.
The
ENMET
EX-5165
gas sensor/transmitter (S/T) is a 3-wire, 24 V
DC
, 4-20 mA S/T for the detection of Carbon Dioxide. The S/T is
meant to be used in conjunction with an appropriate power supply and controller. The
ENMET EX-5165
sensor/transmitter has been
designed and approved to be used in a Class I, Div. 1, Groups B, C, D, classified areas. The approval was issued by CSA
International. Appropriate wiring, conduit and fittings are required for proper installation in a explosion proof rated environment.
C
AUTION
:
Since the sensor/transmitter detects gas only at the sensor location, pay attention to the possible sources of gas, the density
of the gas, locations where the gas may be confined and locations where the gas may damage or injure property or personnel, when
choosing locations of sensor/transmitters.
Also, take into consideration environmental factors when deciding on S/T location. Avoid locations where the S/T may be damaged
by liquid immersion, excessive heat or other known hazards. Also, take precautions to insure condensation inside of the conduit does
not enter the S/T.
3.1 Mounting the EX-5165 Enclosure
Mount the enclosure, using the two mounting holes provided see
Figure 2
. Pay particular attention to the source and density of the
gas being detected when choosing the location. Contact
ENMET
if you have questions regarding your application.
C
AUTION
: Before connecting S/T to controller remove the power source to controller. Failure to do so may cause damage to
sensitive components.
