3.0 Installation of the EX-5155-MOS
C
AUTION
: Area must be declassified during installation.
The
ENMET
EX-5155-MOS gas sensor/transmitter (S/T) is a 3
-wire, 24 V
DC
, 4-20 mA S/T for the detection of toxic gas. The S/T is
meant to be used in conjunction with an appropriate power supply and controller. The
ENMET
EX-5155-MOS 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 envir
onment.
C
AUTION
:
Since the sensor/transmitter detects gas only at the sensor location, pay attention to the possible sources of ga
s, 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 know hazards. Also, take precautions to insure condensation insid
of the conduit does not enter the S/T.
3.1 Mounting the EX-5155-MOS 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. Mount the S/T near the ceiling for lighter than air gases /vapors
and near the floor
for heavier then air gas/vapors. 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.
