2 Installation
Electronics can be destroyed by electrostatic discharge (ESD). Therefore the installation work
should be done only by persons connected to ground, e. g. by standing on a conductive floor or
by taking appropriate grounding measures (acc. to DIN EN 100015).
2.1 Mounting Instructions
See description of the SB2, MSC2 and MSB2 devices.
When choosing the mounting site please pay attention to the following:
The mounting height depends on the relative density of the gas type to be monitored.

Table Mounting Heights
Choose mounting location of the sensor according to the local regulations.
Consider ventilation conditions! Do not mount the sensor near the airflow (air passages, suction holes
etc.).
Mount the sensor at a location with minimum vibration and minimum variation in temperature (avoid
direct sunlight).
Avoid locations where water, oil etc. may influence proper operation and where mechanical damage
might be possible.
Provide adequate space around the sensor for maintenance and calibration work.
