2. PRELIMINARY CHECKS
Before mounting the transmitter, check the compatibility with
the following measurement and safety requirements:
- Explosion protection
- Pressure rating
- Operating voltage limits
- Process and ambient Temperature limits
- Environmental limits
- Corrosion
2.1 EXPLOSION PROTECTION
Explosions could result in death or serious injury. Installation
of this transmitter in a Hazardous Area (i.e. a potentially
explosive atmosphere) must be in accordance with the
appropriate local, national, and international standards, codes,
and practices. Please review the approvals and marking of the
transmitter shown on the label attached to the transmitter (see
figure 1 - Ref. C), note that this is a sample, read the values on
the real label; if this label is not present, the instrument is not
suitable for installation in Hazardous Areas. It is necessary to

check that all the parameters listed on this label (or on the
certificates enclosed with the transmitter) are in accordance
with the requirements of the area where the transmitter is going
to be installed. See the reference manual for an explanation of
each parameter related to "EX SAFETY". In case of any
discrepancy do not install the transmitter.
For pressure transmitter with ATEX combined approval, before
installation, the transmitter should be permanently marked with
the selected Protection Concept (e.g. intrinsically safe or
explosion proof) on the safety label. The transmitter can be
used only in accordance with this Protection Concept for its
whole life.
Note - The transmitter may be used as a safety
accessory (as defined by the Pressure Equipment
Directive 97/23/EC) i.e. as part of a shutdown system. In
this case it is recommended to select the correct fail safe
mode for the 4-20 mA signal (as per Namur NE43
recommendation). See also the instructions relevant to
fail safe selection (Up/Down scale mode) in the addendum
to the instruction manual on "Use of hardware links on the
secondary electronics" .
