WARNING!
EN 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.
▶
CAUTION!
Damage to the instrument
When working on open electric circuits (printed circuit boards) there is a
risk of damaging sensitive electronic components through electrostatic
discharge.
▶
5.1 Mounting
When the temperature switch is mounted, the temperature must neither drop below the
allowed operating temperature (environment, medium) nor exceed it, even when taking
convection and heat radiation into account.
The installation site must be protected from weather influences and permanent UV
exposure/sun radiation.
Depending on the type of application, the electrical connection must be protected from
mechanical damage.

5.2 Electrical connection

DANGER!
Danger to life caused by electric current

For these media, in addition to all standard regulations, the appropriate
existing codes or regulations must also be followed.
The correct use of grounded working surfaces and personal armbands
is required.
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!
Only connect in an unpowered state!
Only disconnect the mating connector with the voltage disconnected.
Use suitable mating connectors for the current and voltage ranges.
