Wiring Diagrams
1
Provide overload protection and disconnect as required.
3
Actuators may also be powered by 24 VDC.
4
Position feedback cannot be used with Triac sink controller.
The actuator internal common reference is not compatible.
5
Control signal may be pulsed from either the Hot (source)
or the Common (sink) 24 VAC line.
8
Contact closures A & B also can be triacs.
A & B should both be closed for triac source and open for triac sink.
9
For triac sink the common connection from the actuator
must be connected to the hot connection of the controller.
Meets UL requirements without the need of an electrical ground
connection.
WARNING Live Electrical Components!
G
During installation, testing, servicing and troubleshooting of this product, it
may be necessary to work with live electrical components. Have a qualifi ed
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.

Note
• Connect via safety isolation transformer.

Note
When several actuators are connected in parallel,
the maximum cable length must be divided by the
number of actuators.
Note
There are no special restrictions on installation if
the supply and data cable are routed separately.
