7.4.1. 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.
7.4.2. Requirements to Mechanics
7.4.2.1. Requirements for Usage as Intrinsically Safe Apparatus
Protect the device from impact effects by mounting in a surrounding
enclosure if it is used in the temperature range between the minimum
permissible ambient temperature and -20 °C.
Mount the device with at least a degree of protection of IP20 according
to IEC/EN 60529.
7.4.2.2. Requirements for Equipment Protection Level Gc (ec)
Mount the device in a way that the device is protected against mechanical
hazard.
protect the cables from tensile load and torsional stress.
7.4.2.3. Requirements for Equipment Protection Level Dc
Mount the device in a way that the device is protected against mechanical
hazard.
protect the cables from tensile load and torsional stress.
7.4.3. Requirements in Relation to Ultraviolet Radiation
7.4.3.1. Requirements for Equipment Protection Level Gc (ec)
Mount the device in such a way that it is protected from ultraviolet
radiation.
Install the cables and connection lines in such a way that they are
protected from ultraviolet radiation.
7.4.3.2. Requirements for Equipment Protection Level Dc
Mount the device in such a way that it is protected from ultraviolet
radiation.
Install the cables and connection lines in such a way that they are
protected from ultraviolet radiation.
8. Operation, Maintenance, Repair
Observe the specific conditions of use.
Safety-relevant markings are found on the nameplate of the device or the
nameplate supplied.
Do not use a damaged or polluted device.
Do not repair, modify, or manipulate the device.
Modifications are permitted only if approved in this instruction manual and
in the device-related documentation.
If there is a defect, always replace the device with an original device.
Do not remove the warning markings.
8.1. Requirements for Usage as Intrinsically Safe Apparatus
Only operate the device with intrinsically safe circuits according to IEC/EN
60079-11.
The type of protection is determined by the connected intrinsically safe
circuit.

Observe the temperature table for the corresponding equipment protection
level in the certificate.
Also observe the maximum permissible ambient temperature stated in the
technical data. Keep to the lower of the two values.
8.3. Requirements for Equipment Protection Level Gb
Observe the temperature table for the corresponding equipment protection
level in the certificate.
Also observe the maximum permissible ambient temperature stated in the
technical data. Keep to the lower of the two values.
8.4. Requirements for Equipment Protection Level Gc (ec)
Do not exceed the maximum permissible operating voltage U
Tolerances are not permitted.
Do not exceed the maximum permitted output current. Prevent short
circuits.
8.5. Requirements for Equipment Protection Level Da
Observe the temperature table for the corresponding equipment protection
level in the certificate.
Also observe the maximum permissible ambient temperature stated in the
technical data. Keep to the lower of the two values.

technical data. Keep to the lower of the two values.
9. Delivery, Transport, Disposal
Check the packaging and contents for damage.
Check if you have received every item and if the items received are the
ones you ordered.
Keep the original packaging. Always store and transport the device in the
original packaging.
Store the device in a clean and dry environment. The permitted ambient
conditions must be considered, see datasheet.
The device, built-in components, packaging, and any batteries contained
within must be disposed in compliance with the applicable laws and
guidelines of the respective country.
