Proportional Damper Actuator, Spring Return Fail-Safe, Multi-Function Technology

®

Wiring Diagrams

1

Provide overload protection and disconnect as required.

2

CAUTION

Equipment damage!

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

3

Actuators may also be powered by 24 VDC.

5

For end position indication, interlock control, fan startup, etc., AF24-MFT-
S US incorporates two built-in auxiliary switches: 2 x SPDT, 7A (2.5A)
@250 VAC, UL Approved, one switch is ﬁxed at +5, one is adjustable 25
to 85.

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

The ZG-R01 500

7

resistor may be used.

WARNING

Live Electrical Components!

During installation, testing, servicing and troubleshooting of this product, it maybe

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.
