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 switch the power supply on once the instrument has
been properly installed.
5.1 Mechanical mounting
Protect measuring instruments from contamination, high temperature
fluctuations and vibrations. In order to avoid any additional heating,
the instruments must not be exposed to direct solar irradiation while
in operation. The ventilation duct temperature sensor can be fastened
directly to the ventilation duct using either a mounting flange or screws.
The IP65 protection is guaranteed, even without screwing down the case
cover. The temperature sensor is fixed to the ventilation duct using the
mounting clip. If condensation could form in the thermowell, it is essential
to install it in such a way that any condensation can drain off.
