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.

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

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)

Auxiliary Switches The MA40-704X-501 series actuators include one built-in SPDT auxiliary switch which can be used for interfacing or signaling (e.g., for fan start-up). The switch is adjustable between 0° and 95° of rotation (0 to 1 scale). The MA4X-715X-502 and MA4X-707X-502 series actuators include two built-in SPDT auxiliary switches which can be used for interfacing or signaling (e.g., for fan start-up). The switch position near the normal (spring return) position is fixed at 5°. The o
