5.1 Supplementary safety instructions for hazardous areas

DANGER!
Danger to life from explosion
Incorrect mounting and non-compliance with the contents of this chapter can
lead to a risk of explosion.
▶
Carefully read and comply with the following sub-chapters.
DANGER!
Damaged diaphragm
If the diaphragm is damaged, the explosion protection is no longer
guaranteed. Through any explosion resulting from this, there will be a high
danger to life.
▶
Before commissioning, the diaphragm should be checked for visible
damage. Leaking fluid is indicative of damage.
▶
Protect the diaphragm from contact with abrasive media and against any
impacts.
Observe the information given in the type examination certificate and the country-specific
regulations for installation and use in hazardous areas (e.g. IEC 60079-14, NEC, CEC). If
this is not observed, serious injuries and damage to property could occur.
The installation of the instrument should be made in such a way that the permissible
operating temperature, also considering the effects of convection and thermal radiation,
neither exceeds nor falls below the permissible limits.

5.2 Mechanical mounting

The instrument may only be installed and mounted by skilled personnel.
5.2.1

Requirements for mounting point

The display unit of the process transmitter can be adapted to the installation site.
→ See chapter 2.2 "Description"
No hazardous environment/flammable atmosphere, except for instruments that are
■
explicitly suitable for installation in or mounting to equipment in explosive atmospheres.
Mechanical vibration/mechanical shock within the permissible values, see chapter 15
■
"Specifications".
Sufficient space for a safe electrical installation.
■
Operating elements can be accessed following the mounting.
■
Observe the permissible medium and ambient temperatures. These are constituent
■
elements of the order confirmation.
