Any legal regulations or regulations issued by authorities must be observed during assembly. • The device may only be opened at the manufacturer‘s site. It does not contain any parts that can be replaced or repaired by the user. • When calculating the required torque, the specifications supplied by the damper manufactur­ ers (cross section, design, installation site), and the air flow conditions must be observed. • The device contains electrical and electronic components and is not allowed to be disposed of as household refuse. All locally valid regulations and requirements must be observed. T2-CM24G-.. • en • v1.1 • 08.2008 • Subject to changes /2

CM24G-.. Damper actuator, AC/DC 24 V, 2 Nm, IP66 Product features Simple direct mounting Simple direct mounting on the damper spindle with a universal spindle clamp (∅ 6 ... 12.7 mm). The actuator is then secured with the anti-rotation strap supplied, to prevent it from rotating. Manual override Manual override with magnet possible (the gear is disengaged as long as the magnet adheres to the symbol . The magnet for gear disengagement is integrated in the position indicator. U Adjustable angle of rotation High functional reliability Adjustable angle of rotation with mechanical end stops. The actuator...
