3.2 Personnel qualification
Risk of injury due to insufficient qualification Improper handling can
lead to considerable personal injury and property damage.
The activities described in these operating instructions may only be
performed by qualified personnel with the following qualifications.
Keep unqualified personnel away from the hazardous areas.
For mounting and commissioning of the sensor, these persons must be familiar with
the applicable country-specific directives and standards, and have the appropriate
qualification. You must have knowledge of measurement and control technology, be
familiar with electrical circuits and be able to carry out the work described and recog-
nize possible hazards independently. Depending on the operating conditions, other
knowledge may also be required, e.g. about aggressive media.
3.3 Special hazards
Observe the country-specific regulations (e.g. standards) and, in the
case of special applications, observe the applicable standards and
directives (e.g. for hazardous media such as Acetylene, flammable
or toxic substances as well as refrigeration plants and compres-
sors).
If the relevant regulations are not observed, serious personal
injury and damage to property may result!
Electrostatic discharge (ESD) protection is required. Proper use of
grounded work surfaces and personal wrist straps is required when
working with open circuits (printed circuit boards) to prevent damage
to sensitive electronic components from electrostatic discharge.
There is danger to life from electric current. There is a immediate risk
of death if live parts are touched. Installation and mounting of
electrical equipment may only be carried out by qualified electricians.
When operating with a defective power supply unit (e.g. short-circuit
from mains voltage to output voltage), life-threatening voltages can
result at the device.
Residual media in devices that have been removed can be
hazardous to persons, the environmet and equipment. Sufficient
precautions must be taken. This device must not be used in safety or
emergency stop devices. Incorrect applications of the device can
lead to injuries. In case of a fault, aggressive media at extreme
temperatures and under high pressure or vacuum may be present at
the device.
