INSTALLATION NOTES
Provide overload protection and disconnect as required.
Actuators may also be powered by 24 VDC.
Actuators with plenum cable do not have numbers; use color codes instead.
22 Actuators and controller must have separate transformers.
23 Consult controller instruction data for more detailed information.
24Resistor value depends on the type of controller and the number of actuators. No resistor is used for one actuator. Honeywell® resistor kits may also be used.
25 To reverse control rotation, use the reversing switch.
46Actuators may be controlled in parallel. Current draw and input impedance must be observed.
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.
