Direct-mount on/off electric spring return actuators for damper control, operating on AC 24 V, DC 24 V, AC 120 V, or AC 230 V power. They provide 70 lb·in. (8 N·m) of running and spring return torque without damper linkages, and the spring return direction is selectable via mounting orientation. The -xxC models add two integral line-voltage SPDT auxiliary switches.

the tab on the anti-rotation bracket remains properly
positioned in the slot on the actuator, and that the
actuator remains parallel to the mounting surface.

5. Slide the actuator onto the damper shaft, and
position the anti-rotation bracket tab into the slot at
the bottom of the actuator as illustrated in Figure 6.

Self-Drilling Sheet Metal Screws (2) stroke-limiting stop can be attached in the field to the
shaft coupler side of the actuator to reduce the rotation
range. Attaching the stroke-limiting stop in the furthest
