DANGER: Hazard with a high risk and
that will result in death or serious
injury if not prevented.
WARNING: Hazard with a moderate
risk and that may result in death or
serious injury if not prevented.
CAUTION: Hazard with a low risk and
that may result in slight or moderate
injury if not prevented.
ATTENTION (NOTE): Risk of damage
to property if informaon is not
observed.
2.1 How warnings are structured and what they mean
When performing dierent types of work either with the or on the RHE42
Coriolis transmier, the personnel carry out steps that could entail hazards.
These steps are therefore preceded by a warning.
Warnings are always structured as follows:
■Warning symbol
■Signal word:
–DANGER
–WARNING
–CAUTION
–ATTENTION
■Descripon of the type of hazard and how it arises
■Descripon of the potenal consequences of disregarding the hazard
■Descripon of measures for prevenng the hazard

2.2 Safety and associated safety measures
DANGER
Risk to life if the informaon in this installaon guide is not
observed!
If the informaon in this installaon guide is not observed, this
will result in serious injury or death.
−Read and observe the informaon in this installaon guide
before working either with the or on the RHE42 Coriolis
transmier.
−Take the safety instrucons and warnings seriously and
follow the measures for prevenng the hazard.
−Work carefully in order to prevent accidents resulng in
personal injury or damage to property.
−Keep the installaon guide safe and make it available to
anyone working either with the or on the RHE42 Coriolis
transmier.
DANGER
Risk to life due to explosive dust and gas atmospheres igning!
When working in hazardous areas there is a risk that explosive
dust and gas atmospheres will be ignited by sparks or naked
ames.
−Have work in hazardous areas performed only by trained
and instructed specialist personnel.
−Observe any country-specic guidelines that apply to work
performed in hazardous areas.
■Explosion protecon in areas with explosive dust and gas atmospheres
Explosive dust and gas atmospheres can cause major explosions and re.
–Please observe the informaon concerning explosion protecon in
Appendix A, see: ⮫
Chapter 14 ‘Appendix A: Ex-Safety Instrucons
(product approval informaon)’ on page 95
.
–In hazardous areas, only use the RHE42 Coriolis transmier in conjunc-
on with intrinsically safe RHM Coriolis sensors. The classicaon can be
found on the type label on the RHM Coriolis sensor.
–The RHE42 Coriolis transmier must be installed and maintained in
accordance with the applicable standards governing electrical installa-
ons in hazardous areas.
–The connecng cable (ARHE-Cx) between the RHM Coriolis sensor and
RHE42 Coriolis transmier is intrinsically safe.
–The connecng cable (ARHE-Cx) must not exceed 20 m in length.
–The connecng cable (ARHE-Cx) has been specied for a temperature
range of -50 to +105°C. Avoid any temperatures higher than this. Temper-
atures of below -50°C are permied if the connecng cable (ARHE-Cx)
has been routed in a protecve conduit.
–If the RHE42 Coriolis transmier has been installed in a hazardous area,
do not open it whilst it is energised.
–Observe all naonal regulaons governing how to install, maintain and
repair instruments located in hazardous areas.

■Modicaons, aachments and conversions
Any modicaons to or aachments and conversions on the RHE42 Coriolis
transmier may make the safety devices less eecve or enrely ineecve,
resulng in unforeseeable hazards.
–Do not carry out any technical modicaons or extensions on the RHE42
Coriolis transmier.
■Risk of injury from slipping, tripping or falling when carrying out installaon
work!
There is a risk of serious injury from slipping on or tripping over electrical
cables, supply lines, and tools that are lying around.
–Make sure that nobody could trip over or fall as a result of the electrical
cables when carrying out installaon work.
–Route electrical cables and supply lines such that nobody could slip on or
trip over them and fall.
2.3 Personnel qualicaons
NOTICE
Damage to property due to inadequately qualied personnel!
All electrical work must only be performed by people who have
in-depth experse in electrical engineering (e.g. qualied electri-
cians). These individuals must provide evidence that they have
the requisite experse for performing work on electrical systems
and the associated components (e.g. by having passed an exami-
naon) and have been trained on the specic product(s) in ques-
on.
Mechanical work must only be performed by appropriately
qualied and trained personnel.

3 Intended use
The RHE42 Coriolis transmier displays the measured values for RHM Coriolis
sensors. It can display the mass ow of liquids and gases as well as the medium
density and medium temperature. In addion, the RHE42 Coriolis transmier is
able to calculate variables such as the volume.
Only install and operate the RHE42 Coriolis transmier in locaons with the
following ambient condions:
■Ambient temperature -20 to +60 °C (oponally -40 to +65 °C), see specica-
on on type label:
Fig. 3 ‘Type label’ on page 16
■Altude of max. 3000 m above sea level
■Relave humidity of 10 to 95% (non-condensing)
■In shade; not exposed to direct sunlight
3.1 Impermissible use
The following are examples of impermissible use of the RHE42 Coriolis trans-
mier (i.e. use contrary to its intended use):
■Using the RHE42 Coriolis transmier in locaons other than those specied
above.
■Using the device in life-support systems in the medical, motor vehicle, air-
cra, water cra or mining industries.
