3.2 Stuff qualification
Improper handling can result in considerable injury and damage to
equipment. The activities described in these operating instructions
may only be carried out by skilled stuff who have the qualifications
described below. Keep unqualified stuff away from hazardous areas.
For installation and starting of the flow-meter the stuff has to be familiar with the
relevant regulations and directives of the country and must have the qualification
required. They must have knowledge on measurement and control technology, have
to be acquainted with electric circuits, are capable of carrying out the work described
and can independently recognize potential hazards. Depending on the operation
conditions of the application they have to have the corresponding knowledge, e.g.
of aggressive media.
3.3 Special hazards
For hazardous media such as oxygen, acetylene, flammable or toxic
gases or liquids, refrigeration plants, compressors, etc., in addition to
all standard regulations, the appropriate existing codes or regulations
must also be followed. If you do not observe the appropriate reg-
ulation, serious injuries and/or damage can occur!
A protection from electrostatic discharge (ESD) is required. The
proper use of grounded work surfaces and personal wrist straps is
required when working with exposed circuitry (PCB, printed circuit
boards), in order to prevent static discharge from damaging sensitive
electronic components.
There is a danger of death caused by electric current. Upon contact
with life parts, there is a direct danger of death. Electrical instruments
may only be installed and connected by skilled electrical personnel.
Operation using a defective power supply unit (e.g. short circuit from
the mains voltage to the voltage output) can result in life-threatening
voltages at the instrument.
Residual media in dismounted instruments can result in a risk to per-
sonnel, the environment and equipment. Take sufficient precaution-
ary measures. Do not use this instrument in safety or Emergency
Stop devices. Incorrect use of the instrument can result in injury.
Should a failure occur, aggressive media with extremely high tem-
perature and under high pressure or vacuum may be present at the
instrument.
