Special Conditions for Safe Use (X):
1. This device contains a thin wall diaphragm less than 1
mm thickness that forms a boundary between zone 0
(process connection) and zone 1 (all other parts of the
equipment). The model code and datasheet are to be
consulted for details of the diaphragm material.
Installation, maintenance and use shall take into
account the environmental conditions to which the
diaphragm will be subjected. The manufacturer’s
instructions for installation and maintenance shall be
followed in detail to assure safety during its expected
lifetime.
2. Flameproof joints are not intended for repair.
3. Non-standard paint options may cause risk from
electrostatic discharge. Avoid installations that could
cause electrostatic build-up on painted surfaces, and
only clean the painted surfaces with a damp cloth. If
paint is ordered through a special option code, contact
the manufacturer for more information.
4. Appropriate cable, glands and plugs need to be
suitable for a temperature of 5°C greater than
maximum specified temperature for location where
installed.
I7 IECEx Intrinsic Safety
Certificate: IECEx BAS 12.0071X
Standards: IEC60079-0:2011, IEC60079-11:2011
Markings: Ex ia IIC T4 Ga (–55 °C
≤ T
a
≤ +70 °C)
Special Conditions for Safe Use (X):
1. When fitted with a transient suppression terminal
block, the Model 3051P is incapable of passing the
500V isolation test. This must be taken into account
during installation.
2. The enclosure may be made of aluminum alloy and
given a protective polyurethane paint finish; however,
care should be taken to protect it from impact or
abrasion if located in a Zone 0 environment.
N7 IECEx Type n
Certificate: IECEx BAS 12.0072X

Special Conditions for Safe Use (X):
1. When fitted with a transient suppression terminal
block, the Model 2088 is incapable of passing the 500V
isolation test. This must be taken into account during
installation.
NK IECEx Dust
Certificate: IECEx BAS12.0073X

Markings: Ex t IIIC T50 °C T
500
60 °C Da
Special Conditions for Safe Use (X):
1. Cable entries must be used which maintain the ingress
protection of the enclosure to at least IP66.
2. Unused cable entries must be filled with suitable
blanking plugs which maintain the ingress protection
of the enclosure to at least IP66.
3. Cable entries and blanking plugs must be suitable for
the ambient temperature range of the apparatus and
capable of withstanding a 7J impact test.
