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 & 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.

Precautions Location9 Schneider Electric 1-888-444-1311 www.schneider-electric.com Product Support Services F-26642-9 August 2014 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 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. 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. Mounting Shaft Rotates Clockwise To Open Shaft Rotates Counterclockwise To Open A - LeftA - Right This step determines shaft rotation. Linkage may change damper direction. Long Shaft Short Shaft Min. 3 1/2" (90 mm) 3/8" to 3/4" Diameter (10 mm to 20 mm) 3/8" to 1/2" Square (10 mm to 13 mm) Min. 3/4" (20 mm) Move the damper to its normal position. Verify the controller action is set to match the damper application. Normally closed damper: when damper is closed, actuator position indicator should be at 0°. When damper is open, actuator position indicator should be at 90°. Normally opened damper: when damper is open, actuator position indicator should be at 0°. When damper is closed, actuator position indicator should be at 90°.Next >
