Mounting
Damper Actuator Sizing
Correct sizing of the actuator is necessary for proper control of dampers. The area of
damper that can be controlled by a given actuator is dependent upon the type of damper,
the quality of the damper, the pressure drop across the damper in the closed position, and
the velocity of the air flow through the damper. To obtain actual damper torque requirements,
contact the damper manufacturer.
Damper Shaft Sizing
Use the “Long Damper Shaft” mounting instructions if the damper shaft is at least 4-5/8" 
(117 mm) long.
Use the “Short Damper Shaft” mounting instructions if the damper shaft is shorter than
4-5/8" or the area around the damper shaft is too narrow to allow standard mounting, as
described in the “Long Damper Shaft” mounting section. See Figure-4 for minimum shaft
length.
Min. 4-5/8" (117 mm)
Figure-4 Long Damper Shaft Dimensions.
Caution: The MA50-E2X01 actuator is not designed to be used on aluminum damper
shafts, solid steel shafts smaller than 1/2" diameter round or 1/2" square, or hollow steel
shafts smaller than 3/4" round. The actuator can produce up to 450 in-lbs (51 N-m)
maximum stall torque, which could result in the actuator snapping off an aluminum damper
shaft or an improperly sized steel damper shaft. Refer to Table-2 for nominal damper shaft
sizes.

Mounting the Actuator for Clockwise or Counterclockwise Spring Return
Long Damper Shaft
1. Move the damper to the normal position (usually closed).
– If the damper shaft rotates clockwise to the closed position, mount the actuator with
the side marked “R” facing the installer. See Figure-5.
– If the damper shaft rotates counterclockwise to the closed position, mount the
actuator with the side marked “L” facing the installer. See Figure-6.
Note: The actuator comes equipped with two AM-754 universal mounting clamps. For
damper shafts larger than 1/2" (13 mm) in diameter, the AM-753 universal mounting clamps
are required (order separately). The AM-753 clamps accommodate round shaft sizes
ranging from 3/4" to 1" (19 to 25 mm) or 5/8" (16 mm) square shafts.
2. Slide the actuator over the shaft and into its desired final mounting position. See
Figure-5 or Figure-6.
3. Hand tighten the nuts on both of the actuator’s universal mounting clamps.
4. Align the actuator at 90° (perpendicular) to the damper shaft. See Figure-7.
5. Slide the anti-rotation bracket pin into the mounting slot on the actuator and drill
mounting holes. See Figure-7. For narrow spaces, the AM-752 anti-rotation bracket is
recommended (order separately).
6. Attach one side of the anti-rotation bracket to the mounting surface with one of the
screws provided. Leave the screw loose so that the bracket can be rotated. See
Figure-5 for clockwise or Figure-6 for counterclockwise spring return.
7. Pivot the anti-rotation bracket away from the actuator. See Figure-5 or Figure-6.
8. Loosen the universal mounting clamps, making sure not to move the damper shaft.
Rotate the actuator approximately 5° in the direction which would open the damper. See
Figure-5 or Figure-6.
9. Tighten all of the universal mounting clamp nuts with a 1/2" socket wrench. Apply 
4 to 6 ft. -lbs (5 to 8 N-m) of torque.
10. Manually rotate the actuator toward the full-closed position to apply pressure to the
damper seals. See Figure-5 or Figure-6.
11. Pivot the anti-rotation bracket into place and secure the other side of the bracket onto
the mounting surface with the other screw provided with the actuator. See Figure-5 or
Figure-6.
12. Verify that the damper is in its full-closed position and actuator at 90° (perpendicular) to
the damper shaft. See Figure-5 or Figure-6.

Short Damper Shaft
See Figure-8 for installation of actuator using the AM-676 Universal Shaft Extension.
Installation requires AM-676 Universal Shaft Extension and AM-753 Universal Mounting
Clamps for 3/4" to 1" (19 to 25 mm) shafts, these items must be ordered separately.
1. Loosen the V-clamp nuts on the AM-676 universal shaft extension.
2. Fit the universal shaft extension fully onto the damper shaft. Tighten the universal shaft
extension V-clamp nuts with a 10 mm open-end wrench. Apply 4 to 6 ft. lbs 
(5 to 8 N-m) of torque.
3. Move the damper to the normal position (usually closed).
– If the damper shaft rotates clockwise to the closed position, mount the actuator with
the side marked “R” facing the installer. See Figure-5.
– If the damper shaft rotates counterclockwise to the closed position, mount the
actuator with the side marked “L” facing the installer. See Figure-6.
4. Remove the mounting clamps from the actuator and replace them with the AM-753
universal mounting clamps.
5. Loosen the nuts on both of the AM-753 universal mounting clamps on the damper
actuator.
6. Assemble the damper actuator onto the universal shaft extension, allowing the
extension to slide through the actuator’s universal mounting clamps. Make sure the
actuator is 90° (perpendicular) to the damper shaft. Then, hand tighten the nuts on both
of the actuator’s universal mounting clamps. See Figure-7
Note: If the universal shaft extension protrudes excessively above the damper actuator's
top universal mounting clamp:
•
•

•
remove the damper actuator from the universal shaft extension,
remove the extension from the damper shaft,
shorten the universal shaft extension by cutting it to the desired length,
then proceed to follow mounting instructions.
7. Slide the anti-rotation bracket pin into the mounting slot on the actuator. See Figure-7.
For narrow spaces, the AM-752 anti-rotation bracket is recommended (order
separately).
8. Position the actuator and bracket in the desired final mounting position on the mounting
surface and drill mounting holes. See Figure-8.
9. Attach one side of the anti-rotation bracket to the mounting surface with one of the
screws provided. Leave the screw loose so that the bracket can be rotated. See
Figure-5 for clockwise or Figure-6 for counterclockwise spring return.
10. Pivot the anti-rotation bracket away from the actuator. See Figure-5 or Figure-6.
11. Loosen the universal mounting clamps, making sure not to move the damper shaft.
Rotate the actuator approximately 5° in the direction which would open the damper. See
Figure-5 or Figure-6.
12. Tighten all of the universal mounting clamp nuts with a 1/2" socket wrench. Apply 
4 to 6 ft. -lbs (5 to 8 N-m) of torque.

damper seals. See Figure-5 or Figure-6.
14. Pivot the anti-rotation bracket into place and secure the other side of the bracket onto
the mounting surface using the other screw provided with the actuator. See Figure-5 or

CHECKOUT
This procedure is for checking out a normally closed actuator that is typically mounted
unpowered. It is possible to mount the actuator with power applied for special applications.
After the entire system has been installed and the actuator has been powered up, the
following check can be made for proper system operation. Check for correct operation of the
damper while actuator is being stroked.
1. Apply power to the actuator.
2. Set the controller to cause the actuator to drive open.
3. Check to see that the actuator travels to the full-open position.
4. Remove power from actuator to cause the actuator to drive closed.
5. Check to see that the actuator travels to the fully closed position.
Note: If anticipated damper operation does not occur, verify the Long Damper Shaft or
Short Damper Shaft mounting procedures. Also, verify that the controller has the proper
action (direct or reverse) to match the damper required operation.

THEORY OF OPERATION
The actuator is, by means of dual mounting clamps, directly mounted onto the damper shaft.
The anti-rotation bracket supplied with the actuator prevents lateral movement of the
actuator. The damper actuator is not provided with and does not require, any limiting
switches, but is electronically protected against overloading.
The angle of rotation is electronically limited to 93° ±1°. When reaching the damper or
actuator end position, the motor stops automatically. The position of the actuator is indicated
by means of scale reading 0 to 95°.
MAINTENANCE
Regular maintenance of the total system is recommended to assure sustained optimum
performance. The MA50-E2X01 actuator is maintenance free.
FIELD REPAIR
None. Replace with functional actuator.
