Warning! Specific safety considerations for installation,
commissioning, operation, and maintenance of the Prima PRO Ex
and Sentinel PRO Ex instruments in hazardous areas are given in
Appendix A: Hazardous Area Operation. The points covered in that
section must be considered in addition to the points above.
For Ex systems, the instructions in Appendix A: Hazardous
Area Operation take precedence over content in the rest of the
manual.
For Ex systems, always defer to the instruction in Appendix
A: Hazardous Area Operation.
Note: At full speed, the noise level from the air conditioner fan can
be up to 65 dBA. Although this is below a level considered harmful,
it can be intrusive if the installation is in a confined space, laboratory
environment, or where ambient background noise levels are low.
If the installation is in an environment where ambient temperatures
are not expected to exceed 30°C, a speed limiter can be switched in
to the fan supply, which will reduce the maximum noise level to < 55
dBA.
