APPLICATION AND USE
MDS.20R(M) rotary actuators with electronic return function are designed for the direct operation of dampers up to 4 m2.
All models are equipped with an electronic return function in case of power supply loss and are used in applications where it is ne-
cessary to ensure a xed position of the damper in emergency and/or power-o conditions.

INSTALLATION AND MOUNTING
The actuator is tted directly to the damper and the calmp tightened securely to the damper shaft. A universal anti-rotation bar is
supplied with each actuator and must be tted to prevent rotation during operation.
Mounting position Mechanical limiting angle of rotation
NO
YES The rotation of the actuator can be mechanically limited by
adjusting as follows:
Changing direction of rotation
Default factory setting: CW.
Direction of rotation can be changed by toggling between CW/
CCW switch on the actuator’s housing.

SAFETY NOTES
24 V AC/DC: connect via safety isolating transformer.
230 V AC: to isolate from the main power supply, the system must iincorporate a device which disconnects the phase conductor
(with at least 3 mm contact gap).
