5.1 General
Study these installation instructions carefully before proceeding.
Failure to observe the warnings and instructions may cause a
malfunction or personal hazard. Before installing the transmitter,
check whether the device design meets the requirements of the
measuring point from a measurement technology and safety
point of view.

This applies in respect of the:
—
Explosion protection certification
—
Measuring range
—
Gauge pressure stability
—
Temperature
— Operating voltage
The suitability of the materials must be checked as regards
their resistance to the media. This applies in respect of the:
their resistance to the media. This applies in respect of the:
—
Gasket
— Process connection, isolating diaphragm, etc.
In addition, the relevant directives, regulations, standards, and
accident prevention regulations must be observed (e.g., VDE/
VDI 3512, DIN 19210, VBG, Elex V, etc.). Measurement
accuracy is largely dependent on correct installation of the
pressure transmitter and, if applicable, the associated
measuring pipe(s). As far as possible, the measuring setup
should be free from critical ambient conditions such as large
variations in temperature, vibrations, or shocks.

Important. If unfavorable ambient conditions cannot be avoided for
reasons relating to building structure, measurement technology, or
other issues, the measurement quality may be affected. If a remote
seal with capillary tube is installed on the transmitter, the additional
operating instructions for remote seals and the related data sheets
must be observed.

5.2 IP protection & designation
The housings for 266 transmitters are certified as conforming to
protection type IP66 / IP67 (according to IEC 60529).

The first number indicates the type of protection the integrated
electronics have against the entry of foreign bodies, including
dust.

“6” means that the housing is dust-proof (i.e., no ingress of
dust). The second number indicates the type of protection
the integrated electronics have against the entry of water.

“6” means that the housing is protected against water;
specifically, powerful jets of water under standardized
conditions.
“7” means that the housing is protected against water;
specifically, against the effects of temporary immersion in
water under standardized water pressure and temporal
water under standardized water pressure and temporal
conditions.
5.3 Mounting the transmitter
5.3.1 Transmitter factory configuration consideration
The 266 pressure transmitter in your hands has been factory
calibrated to reflect the published declared performance
specification; no further calibration is required in normal
condition. ABB typically configures 266 pressure transmitters
according to the user requirements. A typical configuration
includes:

condition. ABB typically configures 266 pressure transmitters
according to the user requirements. A typical configuration
includes:
—
TAG number
—
Calibrated span
—
Output linearization
—
LCD display configuration
5.3.2 Hazardous area considerations
The transmitter must be installed in hazardous area only if it is
properly certified. The certification plate is permanently fixed on
the neck of the transmitter top housing. The 266 Pressure
Transmitter Line can have the following certifications:

Warning - General risks. Unused port plug must be in accordance
with the intended type of protection (e.g. intrinsically safe, explosion
proof, etc.) and degree of protection (e.g. IP6x according to IEC EN
60529). See also the addendum for “EX SAFETY” ASPECTS AND
“IP” PROTECTION. In particular, for explosion proof installation,
remove the red temporary plastic cap and plug the unused opening
with a plug certified for explosion containment

Warning - General risks. Model 266 enclosure contains aluminium
and is considered to present a potential risk of ignition by impact or
friction. Care must be taken into account during installation and use
to prevent impact or friction.
