2.5 Operating conditions

Attention
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 connection diagram.
● After installation, put the device immediately into operation.
The actuators are suitable for installation in industrial plants, 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 traffic 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 draught
● dust
