ENG-93001-93222-12.02-1.5M · Printed in Switzerland · ZSD · Subject to technical changes5Dampers up to approx. 1.5m2Open/Close actuator (AC230V)Control by single-pole contact(single-wire control)Improved functional safetyThe damper actuator has no limit switches and is overload-proof. It stopsautomatically when it reaches the damper or actuator end stop.Easy functional checkA functional check of damper operationis simplicity itself: the gearing can be dis-engaged by simply pressing a pushbut-ton on top of the case. While the push-button remains depressed, the dampercan be operated by hand.Simple installationThe damper actuator is fitted with a uni-versal spindle clamp for quick and easymounting directly on the damper spindle.The actuator is supplied with an anti-rotation strap for fixing it in position.Electrical accessoriesSN1, SN2 Auxiliary switches, page 9Mounting instructions, page 10ImportantRead the notes about the use and torquerequirements of the damper actuators onpage 3.Wiring diagramAC 230 V123NM230Parallel connection of several actuatorswith 1-wire control is possible.
