5. Intended Use
The device is only approved for appropriate and intended use. Ignoring
these instructions will void any warranty and absolve the manufacturer
from any liability.
Technical data provided in the datasheet may be partly restrained by the
information given in this instruction manual.
Use the device only within the specified ambient and operating conditions.
The device is an electrical apparatus for hazardous areas.
The certificate applies only to the use of apparatus under atmospheric
conditions.
If you use the device outside atmospheric conditions, consider that the
permissible safety parameters should be reduced.
The device can be used in hazardous areas containing gas, vapor, and
mist.
The device can be used in hazardous areas containing combustible dust.
The device can be used in underground parts of mines as well as those
parts of surface installations of such mines containing firedamp and/or
combustible dust.
5.1. Requirements for Equipment Protection Level Ga
Refer to the relevant certificate to see the relationship between the
connected circuit type, the maximum permitted ambient temperature, the
effective inner reactances, and if applicable the surface temperature or the
temperature class.
The suitability for use of the device at ambient temperatures >60 °C in
conjunction with hot surfaces has been checked by the notified body.
For usage according to ATEX Directive and according to EN 1127-1, the
reduction of the surface temperature to 80 % is not considered.
5.2. Requirements for Equipment Protection Level Gb
Refer to the relevant certificate to see the relationship between the
connected circuit type, the maximum permitted ambient temperature, the
effective inner reactances, and if applicable the surface temperature or the
temperature class.
The suitability for use of the device at ambient temperatures >60 °C in
conjunction with hot surfaces has been checked by the notified body.
5.3. Requirements for Equipment Protection Level Da
Refer to the relevant certificate to see the relationship between the
connected circuit type, the maximum permitted ambient temperature, the
effective inner reactances, and if applicable the surface temperature or the
temperature class.
The suitability for use of the device at ambient temperatures >60 °C in
conjunction with hot surfaces has been checked by the notified body.
5.4. Requirements for Equipment Protection Level Mb
Refer to the relevant certificate to see the relationship between the
connected circuit type, the maximum permitted ambient temperature, the
effective inner reactances, and if applicable the surface temperature or the
temperature class.
The suitability for use of the device at ambient temperatures >60 °C in
conjunction with hot surfaces has been checked by the notified body.
6. Improper Use
Protection of the personnel and the plant is not ensured if the device is not
used according to its intended use.
7. Mounting and Installation
Observe the installation instructions according to IEC/EN 60079-14.
Safety-relevant markings are found on the nameplate of the device or the
nameplate supplied.
Attach the nameplate supplied in the immediate vicinity of the device.
Attach the nameplate so that it is legible and indelible. Take the ambient
conditions into account.
Do not mount a damaged or polluted device.
Mount the device so that it complies with the specified degree of
protection according to IEC/EN 60529.
If you use the device in environments subject to adverse conditions, you
must protect the device accordingly.
Do not remove the warning markings.
Prevent the inside of the device from becoming contaminated when the
connector is disconnected.
7.1. Requirements for Usage as Intrinsically Safe Apparatus
When connecting intrinsically safe devices with intrinsically safe circuits of
associated apparatus, observe the maximum peak values with regard to
explosion protection (verification of intrinsic safety). Observe the
standards IEC/EN 60079-14 or IEC/EN 60079-25.
The type of protection is determined by the connected intrinsically safe
circuit.
7.2. Requirements for Equipment Protection Level Dc
The device is designed for use in an environment with pollution degree 3
according to IEC/EN 60664-1.
Install a series resistor R
V
between the supply voltage and the device.
Alternatively, use a switch amplifier according to IEC/EN 60947-5-6.
When selecting materials for accessories consider that the temperature of
the housing can rise up to 70 °C.
The maximum surface temperature of the device was determined without
a dust layer on the apparatus.
7.3. Specific Conditions of Use
Mount the device so that it complies with the specified degree of
protection according to IEC/EN 60529.
7.3.1. Requirements in Relation to Electrostatics
Information on electrostatic hazards can be found in the technical
specification IEC/TS 60079-32-1.
Do not mount the supplied nameplate in areas that can be electrostatically
charged.
You can reduce the electrostatic hazards by minimizing the generation of
static electricity. For example, you have the following options to minimize
the generation of static electricity:
• Control the environmental humidity.
• Protect the device from direct airflow.
• Ensure a continuous drain off of the electrostatic charges.
Avoid inadmissibly high electrostatic charge of the metal housing
components on the device.
Include the metal housing components in the equipotential bonding.
Avoid inadmissibly high electrostatic charge of the metal connector
components.
Include the metal connector components in the equipotential bonding.
