INSTALLATION
WARNING - For installation in Hazardous Areas, i.e.
areas with dangerous concentrations of e.g. gases or
dusts that may explode if ignited, the installation must be
carried out in accordance with relative standards either EN
60079-14 or IEC 79-14 and/or with local authority
regulations, for the relevant type of protection adopted.
Together with safety information here and after enclosed
see also the Addendum for "Ex Safety" aspects which is
part of this instruction manual.
WARNING - In order to ensure operator safety and
plant safety it is essential that installation is carried out by
suitably trained personnel according to the technical data
provided in the Data Sheet for the relevant model included
in the supplementary documentation, in particular in the
"Operative limits" section.
The transmitter may be mounted on a vertical or horizontal 2-
inch pipe (figg. 4 and 5) by means of the same mounting bracket.
Note: for other installation details see the relevant
Addendum.
WARNING: The transmitter when installed in
accordance with this instruction manual will not be
subjected to mechanical stresses.
WARNING: the transmitter should not be installed
where it may be subjected to mechanical and thermal
stresses or where it may be attached by existing or
foreseable aggressive substances. ABB cannot
guarantee that a construction material is suited to a
particular process fluid under all possible process
conditions. Therefore it is the user responsibility the
selection of suitable wetted parts materials and filling fluid.
The secondary unit of the transmitter may be rotated through
360° approx. with respect to the primary unit without degrading
performance or damaging the internal wiring. Do not force the
primary unit to rotate; use the 2 mm Allen key supplied to unlock
and lock the tang grub screw (see Fig. 7). This feature, obtained
by unscrewing (one turn is sufficient) the Allen screw,
particularly useful for reaching optimum access to the electrical
connections and visibility of the output indicator.

CAUTION - Proper location of the transmitter
with respect to the process pipe will depend upon the service
for which the instrument is used. Care should be exercised
to identify correct process connections.
