M9220-GGx-3 Proportional Electric Spring Return Actuators Installation Instructions

1

Applications

The M9220-GGx-3 Proportional Electric Actuators are 
direct-mount, spring return electric actuators that 
operate on AC/DC 24V power. These bidirectional 
actuators do not require a damper linkage, and are 
easily installed on dampers with 1/2 to 3/4 in. or 12 to 
19 mm round shafts, or 3/8 and 1/2 in. or 
10, 12, and 14 mm square shafts using the standard 
shaft clamp included with the actuator. An optional 
M9220-600 Jackshaft Coupler Kit is available for 
3/4 to 1-1/16 in. or 19 to 27 mm round shafts, or 
5/8 and 3/4 in. or 16, 18, and 19 mm square shafts.

A single M9220-GGx-3 Series Proportional Electric 
Spring Return Actuator provides a running and spring 
return torque of 177 lb·in (20 N·m). Two or three like 
models mounted in tandem deliver twice or triple the 
torque (354 lb·in [40 N·m] or 531 lb·in [60 N·m]). 
Integral line voltage auxiliary switches are available on 
the GGC models to indicate end-stop position or to 
perform switching functions within the selected rotation 
range.

Installation

The M9220-GGx-3 Proportional Electric Spring Return 
Actuators mount directly to the surface in any 
convenient orientation using two M3 x 9.5 mm 
self-drilling sheet metal screws and the anti-rotation 
bracket (parts included with the actuator). No additional 
linkages or couplers are required. Electrical 
connections are color-coded and identified with 
numbers permanently marked on the actuator cable. 
A tag on the actuator cable identifies the electrical 
connections, and wiring details are also included on the 
actuator housing.

IMPORTANT: Use this M9220-GGx-3 Proportional 
Electric Spring Return Actuator only to control 
equipment under normal operating conditions. 
Where failure or malfunction of the electric actuator 
could lead to personal injury or property damage to 
the controlled equipment or other property, 
additional precautions must be designed into the 
control system. Incorporate and maintain other 
devices such as supervisory or alarm systems or 
safety or limit controls intended to warn of, or protect 
against, failure or malfunction of the electric 
actuator.

IMPORTANT: Do not install or use this 
M9220 GGx-3 Proportional Electric Spring Return 
Actuator in or near environments where corrosive 
substances or vapors could be present. Exposure of 
the electric actuator to corrosive environments may 
damage the internal components of the device, and 
will void the warranty.
