2. General

2.1 Proper use

The actuators are intended to be used exclusively for actuating final control elements
(valves, vanes, etc.). Do not use these actuators for any other purpose. Otherwise, a
hazard of personal injury or of damage to or impairment of the operational reliability of
the device may arise.

2.2 Safety and precautions

When mounting the actuator in areas which may be accessed by unauthorized per-
sons, take the required protective measures.
- The actuators perform movements for positioning vanes and valves. Handle proper-
ly and with care. Otherwise, a hazard of bruise injuries may arise.
- When changing the oil of the actuator, thoroughly remove any oil that may have run
down on the floor during the procedure to avoid accidents.
- Dispose of the waste oil in compliance with the respective local regulations. Make
sure that no waste oil reaches the water cycle
- Only qualified specialists who have been trained for these tasks are authorized to
mount and adjust the control actuator, and to make the electrical connection.
- When working on the actuator itself or the electronics always observe the locally val-
id accident prevention regulations and the regulations concerning the construction
of technical installations.

3. Storage

The actuators may be stored under moist and aggressive condition for a short time. The
equipment is protected against external corrosive influences. However, direct expo-
sure to rain, snow, etc. must be avoided
Actuators, equipped with an anti condensation heater, are additionally protected by
desiccant, which is placed in the following locations:
Motor: . . . . . . . . . . . . . . . . . . . . . . . . . . . . under brake cover
Position sensor: . . . . . . . . . . . . under position sensor cover
Electronics (delivered separately): . . . . in terminal enclosure
The desiccant guarantees sufficient protection for approximately 150 days. It can be
regenerated at a temperature of 90° C within 4 h.
The desiccant must be removed prior to commissioning the actuator or the electronics.

3.1 Long-time storage

If you intend to store or transport the device for a longer time, we recommend to wrap
it in plastic foil and add desiccant. Regularly check if the desiccant is still active.

4. Delivery settings
