5. Commissioning, operation
Only use original parts.
WARNING!
Physical injuries and damage to property and the environment caused
by hazardous media
Upon contact with hazardous media (e.g. oxygen, acetylene, flammable
or toxic substances), harmful media (e.g. corrosive, toxic, carcinogenic,
radioactive), and also with refrigeration plants and compressors, there is a
danger of physical injuries and damage to property and the environment.
Should a failure occur, aggressive media with extremely high temperature
and under high pressure or vacuum may be present at the instrument.
▶ For these media, in addition to all standard regulations, the appropriate
existing codes or regulations must also be followed.
▶
Wear the requisite protective equipment (see chapter 3.6 "Personal
protective equipment").
DANGER!
Danger to life caused by electric current
Upon contact with live parts, there is a direct danger to life.
▶
The instrument may only be installed and mounted by skilled 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!
5.1 Mechanical connection
The installation of the thermocouple should be made so that the temperature neither drops
below the permissible operating temperature (environment, medium) nor exceeds it, even
when taking convection and heat radiation into account.
5.2 Electrical connection
Only connect cables and lines in an unpowered state!
■
Fine-stranded leads must be finished with end splices.
■
Cables used must comply with the respective requirements in terms of stability and
■
temperature.
Connection cables must be run so that any mechanical damage is prevented.
