Precautions
General
Warning:
• Electrical shock hazard! Disconnect the power supply (line power) before installation to
prevent electric shock and equipment damage.
• Make all connections in accordance with the job wiring diagram and in accordance
with national and local electrical codes. Use copper conductors only.
Caution:
• Avoid electrical noise interference. Do not install near large contactors, electrical
machinery, or welding equipment.
• Do not drill holes in actuator body. Six pre-drilled holes are located on each side, under
the label, to accept #10-24 thread-forming screws for mounting accessories.
Caution: The MX41-707X and MX41-715X actuators are equipped with a manual
override.
• The manual override is to be used only when power is not applied to the unit.
• If the universal clamp is not set to 0° on the position indicator, manually wind the
actuator in the direction indicated with hex wrench from -5° to 0° and lock with a
screwdriver.
• When operating manual override, back off 5° from full open mechanical stop to ensure
proper release.
• Do not attempt to use the manual override with actuators mounted in tandem. Damage
to the gear train may occur.

F-26642-8
Mounting
Caution: To remain in NEMA 2/IP54 compliance, the MA4X-715X and MA4X-707X series
actuators should be mounted with conduit end down.
Mount the TAC DuraDrive Actuator directly on the damper shaft in locations that clear the
maximum dimensions of the actuator case and allow the actuator to be mounted flush to the
surface of the terminal box and perpendicular to the damper shaft.
Note: Some terminal boxes have sheet metal screw heads or other protrusions near the
damper shaft. In these cases, a spacer or shim may be added under the anti-rotation
bracket of the actuator to make the actuator perpendicular to the shaft.
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 3-1/2"
(90 mm) long.
Use the “Short Damper Shaft” mounting instructions if the damper shaft is shorter than 3-1/2"
(90 mm) or the area around the damper shaft is too narrow to allow standard mounting, as
described in the “Short Damper Shaft” mounting section.
MA40-704X Series Installation
Note: The MA40-704X series actuator comes equipped with standard universal mounting
clamp. For damper shafts larger than 5/8" (16 mm) in diameter, the AM-710 universal
mounting clamp is required (order separately). The AM-710 clamp accommodates shafts
sizes up to 3/4" (19 mm) diameter shafts.

Jackshaft Installation
(MA40-704X Series)
The MA40-704X actuator is designed for use with jackshafts up to 3/4" (19 mm) in diameter.
In most applications, the MA40-704X actuator may be mounted in the same manner as a
standard damper shaft application. If the jackshaft diameter is larger than 5/8" (16 mm) in
diameter, the optional AM-710 universal clamp must be used.
(MA4X-715X and MA4X-707X Series)
The MA4X-715X and MA4X-707X actuators are designed for use with jackshafts up to 1.05"
(27 mm) in diameter. In most applications, the actuator may be mounted in the same manner
as a standard damper shaft application. If the jackshaft diameter is larger than 3/4" (19 mm)
in diameter, the optional AM-687 universal clamp must be used.
Multiple Actuator Mounting
If more torque is required than one actuator can provide a second actuator may be mounted
to the damper shaft, using the AM-673 multiple mounting bracket. See Figure-4.
Multiple actuators may be powered from one transformer provided the following rules are
followed:
• The total current draw of the actuators (VA rating) is less than or equal to the rating of
the transformer and less than the rating of the control circuit.
• Polarity on the secondary of the transformer is strictly followed.
– All L2 wires from all actuators are connected to the common lead on the
transformer.
– All L1 wires from all actuators are connected to the hot lead.
Caution: Mixing the L2 and L1 wires on one lead of the transformer may result in erratic
operation or failure of the actuator and/or controls.
Caution: Do not attempt to use the manual override with actuators mounted in tandem.
Damage to the gear train may occur.
Multiple actuators positioned by the same control signal may be powered from multiple
transformers provided the following rules are followed:
• The transformers are properly sized.
• All L2 wires from all actuators are tied together and tied to the negative lead of the
control signal.

Rotation Limitation
Rotation Limitation for MA40-704X Series
The Stop Block is used in conjunction with the tab on the universal clamp or the AM-709
position indicator. In order to function properly, the clamp or indicator must be mounted
correctly.
The Stop Block controls the rotational output of the MA40-704X and MF40-704X-501
actuators. It is used in applications where a damper has a designed rotation that is less than
90°, for example with a 45° or 60° rotating damper.
1. Determine the amount of damper rotation required. The actuator stop block provides
limited rotation from 40° to 95°.
2. Loosen the screw securing the stop block to the actuator.
Note: The actuator is shipped with the Stop Block mounted to the “L” side. If the damper
application requires the “R” side face the installer, simply remove the Stop Block and screw
and move it to the new location.
3. Slide the stop block into position, so that its edge lines up with the degree graduation
on the actuator face which corresponds with the required rotation. See Figure-5.
4. Secure the stop block in place.
5. Test the damper rotation by applying power. Re-adjust if necessary.

Rotation Limitation for MA4X-715X and MA4X-707X Series
The AM-689 rotation limiter is used in conjunction with the tab on the universal clamp or the
AM-686 position indicator which comes with the AM-689. In order to function properly, the
clamp or indicator must be mounted correctly.
The AM-689 rotation limiter controls the rotational output of the MA4X-715X, MA4X-715X-
502, MA4X-707X, and MA4X-707X-502 actuators. It is used in applications where a damper
has a designed rotation that is less than 90°, for example with a 45° or 60° rotating damper.
1. Determine the amount of damper rotation required.
2. Locate the AM-689 rotation limiter on the actuator so that its edge lines up with the
degree graduation on the actuator face which corresponds with the required rotation.
3. Find the appropriate cross-hair location through the slot of the rotation limiter. This is
the mounting location for the retaining screw.
4. Pierce through the label material to allow easy fastening of the retaining screw.
5. Position the rotation limiter back to the desired position, making sure the locating “teeth”
on the rotation limiter are engaged into the locating holes on the actuator.
6. Fasten the rotation limiter to the actuator using the self-tapping screw provided.
7. Test the damper rotation by applying power. Re-adjust if necessary.

CHECKOUT
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. Actuator and damper should be driven to their powered
position.
2. On the MA4X-7XXX-50X models, check for correct auxiliary switch operation.
3. Break power to the actuator. Actuator and damper should return to their normal, or
spring return position.

THEORY OF
OPERATION
The actuators are mounted directly onto a damper shaft using a universal V-clamp. When
power is applied, the actuator rotates 95° to its powered position, at the same time tensing
the spring return safety mechanism. When power is removed, the spring returns the actuator
to its normal position. The actuators provide true mechanical spring return operation for
reliable, positive close-off on air tight dampers.
The MA4X-707X, MA4X-707X-502, MA4X-715X, and MA4X-715X-502 actuators are
equipped with a graduated position indicator showing -5° to 90°. The MA40-704X and
MA40-704X-501 are equipped with a graduated position indicator showing 0 to 1.
The MA40-704X-501 models are provided with 1 built in auxiliary switch. The SPDT switch
is provided for interfacing or signaling, for example, fan start-up. The switching function is
adjustable between 0° to 95° rotation (0 to 1 scale).
The MA4X-715X-502 and MA4X-707X-502 models are provided with 2 built in auxiliary
switches. The SPDT switches are provided for interfacing or signaling, for example, fan
start-up. The switching function is adjustable on one switch between 25° to 85° rotation and
the other switch is fixed at 5°.
The MA41-707X-XXX and MA41-715X-XXX actuators are equipped with a manual override
mechanism. This allows the actuator to be manually positioned at any point between -5o and
85o. This mechanism is accessible on both sides of the actuator and can be used to ensure
tight close-offs for valves and dampers. The manual override should not be used while a unit
is powered or on units that are mounted in tandem.
MAINTENANCE
FIELD REPAIR
Regular maintenance of the total system is recommended to assure sustained optimum
performance. The actuators are maintenance free.
