M9203-AGA-2Z, M9203-AGB-2Z
Applications
The M9203-AGx-2(Z) Series On/Off and Floating Point
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
1/4 to 1/2 in. (6 to 12 mm) 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-AGx-2(Z) Series On/Off and Floating
Point 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-AGA-2(Z) 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.

IMPORTANT: Use this M9203-AGx-2(Z) Series
On/Off and Floating Point Electric Spring Return
Actuator only to control equipment under normal
operating conditions. Where failure or malfunction of
the 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 actuator.
IMPORTANT : Utiliser ce M9203-AGx-2(Z) Series
On/Off and Floating Point Electric Spring Return
Actuator uniquement pour commander des
équipements dans des conditions normales de
fonctionnement. Lorsqu'une défaillance ou un
dysfonctionnement du actuator risque de provoquer
des blessures ou d'endommager l'équipement
contrôlé ou un autre équipement, la conception du
système de contrôle doit intégrer des dispositifs de
protection supplémentaires. Veiller dans ce cas à
intégrer de façon permanente d'autres dispositifs,
tels que des systèmes de supervision ou d'alarme,
ou des dispositifs de sécurité ou de limitation, ayant
une fonction d'avertissement ou de protection en
cas de défaillance ou de dysfonctionnement du
actuator.
Installation
The M9203-AGx-2(Z) Series On/Off and Floating Point
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.
