10 Hazardous Area considerations
Specific conditions of use (X)
The SIL2 version is identified by option code NL (i.e.
PXS100XXXXXX...NL). It is not capable of withstanding a
500 V r.m.s. dielectric strength test according to Clause 6.3.13
of IEC 60079-11:2011.
This shall be taken into account in any equipment installation.
When the PGS100/PAS100 pressure transmitter is used for
group III Db, do not install in area that is subject to flowing
dust.
Explosion protection
Explosion-protection should be conducted in accordance with
Directive 2014/34/EU (ATEX). When installing certified
transmitters (electrical connection, grounding / potential
equalization, etc.), observe national regulations, explosion-
protection directives and standards. The certified method of
protection for the transmitter is provided on the Ex plate.
Type-examination certificate/Declaration of
conformity
For transmitters with hazardous location design, the EU
declaration of conformity and this operating instruction should
be complied with. The EU type examination certificates to be
applied are available for download online on the ABB website.
Type of protection "intrinsic safety Ex ia"
Only intrinsically safe devices may be installed in the
transmitter signal circuit. The signal circuit can be interrupted
while the transmitter is in operation (e.g., clamping/
unclamping signal lines).
The housing may be opened during operation, in absence of
explosive atmosphere.
Transmitters with and without remote seals and featuring type
of protection "intrinsic safety Ex ia" may be directly integrated
into the partition separating application for gas Zone 0 and
Zone 1 (sensor diaphragm in Zone 0, transmitter in Zone 1), and
application for dust Zone 20 and Zone 21 (sensor diaphragm in
Zone 20, transmitter in Zone 21), provided that the power is
supplied via an intrinsically safe circuit with type of protection
"Ex ia".
Use in areas with combustible dust
Installation should be performed in accordance with the EN
60079-14 installation regulations.
The transmitter should only be connected using cable glands
certified in accordance with Directive 2014/34/EU (ATEX). The
cable gland must conform to IP rating IP 67.
The smoldering temperature of the dust must be at least 75 K
above the maximum surface temperature of the transmitter.
The maximum surface temperature is 120 °C (248 °F) or T135 °C.
WARNING - RISK OF EXPLOSION
When using remote seals with an anti-stick coating, be aware
of the risk of electrostatic discharge (with consideration
given to the filling material and transport speed).
WARNING - RISK OF EXPLOSION
Opening the housing during operation (with the supply
voltage switched on) is not permitted. Opening the cover
presents a risk of spark formation and, therefore, explosion.
Only open the housing when the supply voltage is switched
off).
Use of handheld terminal / PC
If a handheld terminal or a PC is being used for communication
/ configuration / parameterization in a potentially explosive
atmosphere with type of protection "intrinsic safety", the
devices used must be certified accordingly.
This applies even if the device is only connected for a short
period of time. This proof of "intrinsic safety" must be supplied
in addition to the transmitter.
