5. INSTALLATION
*WARNING*
STATIC ELECTRICITY - Installation, wiring, configuration, or other activity may
require handling or disassembly of the transmitter circuit card assemblies (CCA).
Handling of a CCA without proper precautions can expose the electronic components
to the possible damage from static electricity discharge.
Try to ensure you are grounded when handling a CCA. If continuous grounding is
not practical, touch some metal item, which is known to be grounded.
walking around after this as you can regenerate a static charge. Note that the
smallest static discharge, which is noticeable by humans, is 3,000 Volts.
noticeable, significant discharge may be as high as 30,000 Volts
5.1 Mounting
The QTS-6100 Sensor/Transmitter should be mounted where the gas to be measured is most likely to be
present. This location will be dependent on the source of the target gas and whether that gas is lighter or
heavier than air. Air circulation and mixture should also be taken into account. The following table
provides recommended mounting location based on the molecular weight of the gas:

QTS-61230 Ethylene Oxide
QTS-61240 Ozone
Where possible, the sensor/transmitter should be mounted where it is accessible for the purposes of routine
re-calibration and periodic sensor replacement. Sufficient room should be left to allow the enclosure cover
to be removed. On units with industrial explosion-proof enclosures, sufficient room should be left to allow
the connection of the calibration adapter to the sensor assembly. For sensor element replacement there will
need to be enough room to reach into the sensor assembly.
*CAUTION*
The sensor assemblies on the industrial explosion-proof enclosures are designed for
integral mounting only.
transmitter may be possible, but may require special wiring considerations. If you
must remote mount the sensor from the transmitter please consult the factory for
recommendations.
