Applications

The M9203-GGx-2(Z) Series Proportional Electric

Spring Return Actuators are direct-mount actuators

that operate on AC/DC 24 V power. These bidirectional

actuators do not require a damper linkage, and are

easily installed on round shafts from

1/4to1/2in.(6to12mm) or square shafts from

1/4 to 5/16 in. (6 to 8 mm) using the standard shaft

clamp included with the actuator.

A single M9203-GGx-2(Z) Series Proportional Electric

Spring Return Actuator provides 27 lb·in. (3 N·m)

running and spring return torque. An integral line

voltage auxiliary switch, available only on the

M9203-xxB-2(Z) models, indicates end-stop position,

or performs switching functions within the selected

rotation range.

M9203-GGA-2 and M9203-GGA-2Z actuators include

plenum-rated cables and are specially configured for

installation in spaces used for environmental

air-handling purposes other than ducts and plenums as

specified in National Fire Protection Association

(NFPA) 70: National Electrical Code section 300.22(C),

Other Space Used for Environmental Air. The space

over a hung ceiling used for environmental air handling

purposes is an example of the type of space for which

these actuators are configured.

Installation

The M9203-GGx-2(Z) Series Proportional Electric

Spring Return Actuators mount directly to the surface in

any convenient orientation using two No. M3.5 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 included on the

actuator housing.

Parts Included

• M9203-GGx-2(Z) actuator

• M9203-603 adjustable stop kit

• M9000-604 anti-rotation bracket with two

No. M3.5 x 9.5 mm, pan-head, cross-recessed

(Phillips), self-drilling and self-tapping screws

Special Tools Needed

• 10 mm wrench/socket

• drill with Phillips bit, driver size 1

IMPORTANT: Use this M9203-GGx-2(Z) Series

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: Before specifying M9203-GGx-2(Z)

Series Proportional Electric Spring Return Actuators

for plenum applications, verify acceptance of

exposed plastic materials in plenum areas with the

local building authority. Building codes for plenum

requirements vary by location. Some local building

authorities accept compliance to UL 1995, Heating

and Cooling Equipment, while others use different

acceptance criteria.

IMPORTANT: Do not install or use this

M9203-GGx-2(Z) Series Proportional Electric Spring

Return Actuators 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.

Counterclockwise (CCW) Spring Return Direction – Clockwise (CW) Powered Operation For CCW spring return direction, mount the actuator to the damper shaft so that Side A of the actuator is away from the damper as illustrated in Figure 2. With power applied, the actuator drives CW from the 0° position and spring returns CCW. Removable Coupler If the damper shaft extends less than 3.31 in. (84 mm), mount the coupler on the face of the actuator closest to the damper. If the damper shaft extends less than 0.

IMPORTANT: The tab on the anti-rotation bracket must fit midpoint in the actuator slot. Positioning the tab midpoint in the slot prevents actuator binding and premature wear, and makes actuator removal easier. 8. Apply power long enough for the actuator to travel a full stroke. Verify that the actuator rotates freely throughout the range. Limiting Rotation Range Using M9203-603 Adjustable Stop Kit 3-1/4 (82.
