Installation
•If the universal clamp is not set to 0° on the position
Inspection
Inspect the package for damage. If damaged, notify the
appropriate carrier immediately. If undamaged, open the
package and inspect the device for obvious damage. Return
damaged products.
Requirements
•Job wiring diagrams
•Tools (not provided):
–#8 sheet metal screws
–10mm open end wrench or socket wrench
–7/16 inch, open end wrench or socket wrench
–1/8 inch, allen wrench
–Appropriate screwdriver(s)
•Appropriate accessories
•Training: Installer must be a qualified, experienced
technician
Precautions
Notices
•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.
•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.
Manual Override
The MX41-707X & MX41-715X actuators are equipped with a
manual override.
•The manual override is to be used only when power is not
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.

This equipment has been tested and found to comply with the
limits for a Class B digital device, pursuant to Part 15 of the
FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in residential installations. This equipment generates, uses, and can radiate radio
frequency energy and may cause harmful interference if not
installed and used in accordance with the instructions. Even
when instructions are followed, there is no guarantee that interference will not occur in a particular which can be determined
by turning the equipment off and on; the user is encouraged
to try to correct the interference by one or more of the following measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and
receiver.
•Connect the equipment to an outlet on a circuit different
from that to which the receiver is connected.
•Consult the dealer or an experienced radio/television

Notice: This is a Class B digital (European Classification)
product. In a domestic en
vironment this product may cause
radio interference in which case the user may be required to take
adequate measures.
Enclosure Rating
Notice: Avoid locations where excessive moisture, corrosive
fumes, vibration, or explosive vapors are present.
Mounting
Notice: To remain in NEMA 2/IP54 compliance, the MA4X-715X
and MA4X-707X series actuators should be mounted with conduit
end down.
Mount the SmartX 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.
: Some terminal boxes have sheet metal screw heads or other
Note
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.
Installation Instructions
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” (90mm) or the area around the damper
shaft is too narrow to allow standard mounting, as described in the
“Short Damper Shaft” mounting section.
