WARNING!
For hazardous media such as oxygen, acetylene, flammable or toxic gases or liquids,
and refrigeration plants, compressors, etc., in addition to all standard regulations, the
appropriate existing codes or regulations must also be followed.
WARNING!
Protection from electrostatic discharge (ESD) required. The proper use of grounded
work surfaces and personal wrist straps is required when working with exposed
circuitry (printed circuit boards), in order to prevent static discharge from damaging
sensitive electronic components.
To ensure safe working on the instrument, the operating company must ensure
■ that suitable first-aid equipment is available and aid is provided whenever
required,
■ that the operating personnel are regularly instructed in all topics regarding work
safety, first aid and environmental protection and knows the operating instructions
and, in particular, the safety instructions contained therein.
DANGER!
Danger of death caused by electric current
Upon contact with live 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 output voltage) can result in life-threatening voltages at the
instrument!
WARNING!
Residual media in dismounted instruments can result in a risk to persons, the
environment and equipment. Take sufficient precautionary 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 temperature and under
high pressure or vacuum may be present at the instrument.
