Installation Instructions

TYPICAL APPLICATIONS (wiring diagrams)

Figure-1 through Figure-3 illustrate typical wiring diagrams for spring return floating actuators. See Available Models.

Figure 1 Typical Wiring Diagram for 24 Vac Basic and Double Auxiliary Switch Models.

MA41-707X-502 and MA41-715X-502 units manufactured prior to the date code 0141 (October 6, 2001) used the following color coding for the auxiliary switches:

Auxiliary Switch 1
Orange:	Fixed auxiliary switch common (com)
Yellow:	Fixed auxiliary switch normally closed (NC)
Violet:	Fixed auxiliary switch normally open (NO)
Auxiliary Switch 2
Orange/white:	Adjustable auxiliary switch common (com)
Violet/white:	Adjustable auxiliary switch normally closed (NC)
Yellow/white:	Adjustable auxiliary switch normally open (NO)

The label information on these units is incorrect. If replacing these units, the auxiliary switch operation of the replacement actuator will be per the product label.

Installation

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 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.

Federal Communications Commission (FCC)

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 technician for help.

Canadian Department of Communications (DOC)

This Class B digital apparatus meets all requirements of the Canadian Interference-Causing Equipment Regulations.

Cet appareil numerique de la classe B respecte toutes les exigences du Reglement sur le material broilleur du Canada.

European Standard EN 55022

Installation Instructions

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.

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.
