5. Commissioning, operation
5.1 Installation
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.

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!
▶
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.
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.
Only connect circuits with the same voltage and type of protection
■
to the switch contacts and connecting cables.
Size the connecting cables for the largest current strength in the
■
circuits.
