Actuators with plenum rated cable do not have numbers on
wires; use color codes instead. Actuators with appliance
cables are numbered.

Actuators may also be powered by 24 VDC.

Meets cULus requirements without the need of an electrical
ground connection.

Equipment damage!
Actuators may be connected in parallel if not mechanically
mounted to the same shaft. Power consumption and input
impedance must be observed.

CAUTION
Indicates a potentially hazardous situation which, if not avoided,
may result in minor or moderate injury. It may also be used to
alert against unsafe practices.
Warnings and Cautions appear at appropriate sections throughout
this manual. Read these carefully.
Hazard Identification
INSTALLATION NOTES
APPLICATION NOTES
Control signal may be pulsed from either the Hot (Source)
or Common (Sink) 24 VAC line.
10
For triac sink the Common connection from the actuator
must be connected to the Hot connection of the controller.
Position feedback cannot be used with a triac sink controller.
The actuator internal common reference is not compatible.

A 500 Ω resistor converts the 4 to 20 mA control signal
to 2 to 10 VDC.

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.
