Title: Ventilmotorer i fyrrom - AVM322.pdf
The concept of synchronous motor/electronics ensures electrical parallel operation of up to five actua- tors of the same type. The actuator is mounted directly on the valve and fixed with screws (no further adjustments are re- quired). The actuator is connected with the valve spindle automatically. As delivered ex works, the actuator spindle is in the middle position. Condensate, dripping water, etc. must be prevented from entering the actuator along the valve spin- dle. The housing contains two break-out cable inlets for two metric plastic cable glands M20×1.5, which are broken out automatically when the cable inlet is screwed in. The cross-section of the power cable must be selected based on the cable length and the number of actuators. With five actuators wired in parallel and a cable length of 50 m, we recommend a cable cross-section of 1.5 mm2 (power consumption of the actuator × 5). According to building installation regulations, the lines must be protected from overload or short cir- cuit.)
