Power consumption and input impedance must be observed.Actuators may also be powered by 24 VDC.Actuators Hot wire must be connected to the control board common. Only connect common to neg. (-) leg of control circuits. Terminal models (-T) have no-feedback.16Actuators are provided with a numbered screw terminal strip instead of a cable.Meets cULus requirements without the need of an electrical ground connection.!WARNING! LIVE ELECTRICAL COMPONENTS!During installation, testing, servicing and troubleshooting of this product, it may be necessary to work with live electrical components. Have a qualified licensed electrician or other individual who has been properly trained in handling live electrical components perform these tasks. Failure to follow all electrical safety precautions when exposed to live electrical components could result in death or serious injury. 24 VAC TransformerLineVolts12316 (1) Common (2) + Hot (3) + InputOn/Off (1) Common (2) + Hot (3) + InputLineVolts1231624 VAC TransformerFloating Point ComHot2316Blk (1) CommonRed (2) + HotWht (3) Y InputLineVolts24 VAC Transformer1Floating Point - Triac Source 216Blk (1) CommonRed (2) + HotWht (3) Y InputLineVolts24 VAC TransformerComHot61Floating Point - Triac SinkNRX24-3-T N4NEMA 4X, On/Off, Floating Point Control, Non-Spring Return, 24 V800-543-9038 USA866-805-7089 CANADA203-791-8396 LATIN AMERICA / CARIBBEANDate created, 11/30/2017 - Subject to change. © Belimo Aircontrols (USA), Inc.Next >
