Installation - ABB 2600T Series Operating Instruction

INSTALLATION

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 2-inch pipe (figg. 4, 5a,
5b, 5c, 6a and 6b) by means of the proper mounting bracket.
The transmitter may also be directly, supported by the piping
connection.

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.

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: 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. See also the paragraph on "Operati-
ve limits".
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.
