Installation Guide
READ THIS INSTRUCTION SHEET AND THE SAFETY WARNINGS
CAREFULLY BEFORE INSTALLING AND SAVE IT FOR FUTURE USE
General Features
The actuators are intended for the operation of air dampers in HVAC
systems. The universal adapter allows them to be mounted directly on the
damper spindle where they are secured with the locking device supplied.

Square spindles: 10...16 mm
f. 1 - Angle of rotation limiting
2- Releasing the adapter
The actuator allows ON/OFF and Floating control use, operating via
contacts. The motor stops running when the damper end-stop or actuator
end-stop is reached. For manual operation of the damper the gearing is
disengaged by means of the self-resetting button (See Figure 2 d.).
WARNING: When calculating the torque required to operate
dampers, it is essential to take info account all the data
supplied by the damper manufacturer.

Installation and adjustment
Figure 3: Mounting Instructions
Installation
Attach the actuator to the damper spindle by means of the adapter and
secure the locking device with the screws provided.
Angle of rotation limiting
An angle-of-rotation/working range (Figure 2 f1.) of less than 90° can be
limited mechanically by repositioning the adapter in 5° steps as required.
The adapter is released by simply pressing the adapter clips on the lower
side of the actuator (Figure 2 f2.).
Selecting the direction of rotation
• In order to reverse the direction of rotation (CW/CCW), loosen screw
(See Figure 1 a.) and remove the cover.
• Reverse the motor connector (See Figure 2 c.).
• Factory setting: Clockwise (CW) rotation.
Wiring
WARNING:
• The electrical connections for the actuators must be
executed in accordance with the relevant legal requirements.
•In order to avoid any personal injury or damage to the
equipment or other property, always isolate the power
supply before commencing any work on the electrical
wiring.
• In order to avoid danger to property, it is important for the
equipment to be used solely for which it is intended.
WARNING: The integrated circuits in the actuator are
sensitive to static electricity. Take suitable precautions.

Electrical connections via safety isolating transformer
• In order to make the electrical connections, loosen screw (Fig. 1 a.) and
remove the cover.
•Actuator wiring diagram according to terminal connection (Fig. 4).
•Parallel connection according to terminal connection (Fig. 5).
•Auxiliary switches according to terminal connection (Fig. 6).
•Feedback potentiometer according to terminal connection (Fig. 7).
•The electrical installation work should be carried out by a qualified
electrician.
• Wrong connections can damage the equipment. Check the connections
before energizing the power supply.
• Local accident prevention regulations should always be adhered to when
installing the actuators.
• The actuator moves about slightly while it is working so it is important to
use flexible leads for the electrical connections.

Auxiliary switches adjustment (See Figure 2 a. - b.)
Example:
Switching position adjustment a. to 30° and b. to 70°.
30°: Depress the manual button (Figure 2 d.) and rotate the adapter (Figure 2 e.)
to the 30° position. Slightly loosen the Phillips screw in the cam wheel a. so
that the wheel can be moved by hand. Rotate the cam wheel
a. counterclockwise until the switch button can be seen. Then tighten-
back the Phillips screw in the cam wheel a..
70°: Rotate the adapter (Figure 2 e.) in the same manner as before to the
70° position. Slightly loosen the Phillips screw in the cam wheel b. so that
the wheel can be moved by hand. Rotate the cam wheel b. clockwise until
the switch button can be seen. Then tighten-back the Phillips screw in the
cam wheel b..
Factory setting of auxiliary switches
The two auxiliary switches a. and b. are factory set at the to approximately
10° CW (a.) and 80° CW (b.).
