Motorized Rotary Actuator baelz 375-E42
2.3 Operating conditions
In case of extreme variations in ambient temperature and high humidity levels, installation of a
heating resistor is recommended to minimise condensation in the actuator.
Actuatorcoverswithsuppressionofthermalbridges(dualcovers)arerecommended.
● Connecttheheater(HZG)asshowninthewiringdiagram.
● Put the device into service as soon as it is installed.
The actuators are suitable for installation in industrial plants and in waterworks and power
plants with a low pollutant concentration.
Foruseoutdoorsorinanenvironmentwithahighpollutantconcentration,suchasheavytrafc
areas,industrialareas(chemicalplants,sewageplants,etc.),coastalareasandtheopensea,
the actuators must have external parts made of non-corrosive material and must be provided
with a special coating.
When used outdoors, the actuator must be protected with an additional cover against
● rain
● direct sunlight
● strong draughts
● dust
3. TRANSPORT AND STORAGE
Risk of injury caused by failure to observe safety regulations!
Caution
● Wear the required personal and other protective equipment.
● Protecttherotaryactuatorfromimpact,shock,vibrationandsimilarinuences.
● Storetherotaryactuator(orthecompleteactuator/valveassembly)inadryplace.
● Observethetransportandstoragetemperaturelimitsof-20to+60°C.
