Wiring for Damper Actuators and Control ValvesGeneral Wiring InstructionsAlways read the controller manufacturer’s installationliterature carefully before making any connections. Follow allCAUTION: It is good practice to power electronic or digital controllersfrom a separate power transformer than that used for actuators or otherend devices. The power supply design in our actuators and other enddevices use half wave rectification. Some controllers use full waverectification. When these two different types of power supplies areconnected to the same power transformer and the DC commons areconnected together, a short circuit is created across one of the diodes inthe full wave power supply, damaging the controller. Only use a singlepower transformer to power the controller and actuator if you know thecontroller power supply uses half wave rectification.instructions in this literature. If you have any questions, contactthe controller manufacturer and/or Belimo.Multiple actuators, one transformerTransformer(s)Belimo actuators require a 24 VAC Class 2 transformer. Theactuator enclosure cannot be opened in the field, there are noparts or components to be replaced or repaired.– EMC Directive: 2004/108/EC– Software Class A: Mode of Operation Type 1– Low Voltage Directive: 2006/95/ECExample: 3 AF Actuators Supplied, 16 Ga. wire (refer to table onpage 3)350 ft.

The TOTAL current draw of the actuators (VA rating) is less than orequal to the rating of the transformer.2. Polarity on the secondary of the transformer is strictly followed.This means that all No. 1 wires from all actuators are connectedto the common leg on the transformer and all No. 2 wires from allactuators are connected to the hotleg. Mixing wire No. 1 & 2 on oneleg of the transformer will result in erratic operation or failure of theactuator and/or controls.Multiple actuators, multiple transformersMultiple actuators positioned by the same control signal may be poweredfrom multiple transformers provided the following rules are followed:1. The transformers are properly sized.2. All No. 1 wires from all actuators are tied together and tied to thenegative leg of the control signal. See wiring diagram.Wire type and wire installation tipsFor most installations, 18 or 16 Ga. cable works well with Belimoactuators. Review job requirements and determine whether a plenumor appliance rated cable is appropriate. Use code-approved wire nuts,terminal strips or solderless connectors where wires are joined. It isgood practice to run control wires unspliced from the actuator to thecontroller. If splices are unavoidable, make sure the splice can bereached for possible maintenance. Tape and/or wire-tie the splice toreduce the possibility of the splice being inadvertently pulled apart.Wire length for actuator installationKeep power wire runs below the lengths listed in the following tables.If more than one actuator is powered from the same wire run, dividethe allowable wire length by the number of actuators to determine themaximum run to any single actuator.866-805-7089 CANADA203-791-8396 LATIN AMERICA / CARIBBEANN40067 - 7/11 - Subject to change. Belimo Aircontrols (USA), Inc.WARNING: The wiring technician must be trained and experiencedwith electronic circuits. Disconnect power supply before attempting anywiring connections or changes. Make all connections in accordancewith wiring diagrams and follow all applicable local and national codes.Provide disconnect and overload protection as required. Use copper,twisted pair, conductors only. If using electrical conduit, the attachmentto the actuator must be made with flexible conduit.
