ADAPTER BRACKET
Adaptor Bracket, positioned between the
motor and the equipment, raises the shaft height
M9484 motor by 0.75 inch to match that of the M941 motor.
This is required on all valve linkage applications,
External Auxiliary Switch applications, and on some
damper linkage applications (either to provide clearance
for the crank arm to rotate through the downward position,
or to allow the damper linkage to reach the shaft).
To mount the motor with the bracket:
1. Mount the bracket to the equipment with existing or
standard bolts.
2. Mount the motor to the bracket using the bolts pro-
vided into the threaded holes of the bracket (see Fig. 3).
For valve linkage applications, the bracket should first
be mounted to the linkage (see Fig. 4). The bracket then
provides a convenient base on which the motor can be
positioned. After the motor shaft is aligned to the linkage,
it can then be attached to the bracket with the 4 bolts
provided. These bolts go through the inner set of holes in

linkage. In general, however, check the following points of
operation when installing a motor and linkage.
1. Linkages for valves and louver type dampers should
be adjusted so that the damper or valve moves through
only the maximum required distance when the motor
moves through its full stroke.
A 220738A Adapter Bracket is packed with replace-
ment motors. Use of this bracket is optional for many
damper applications but may be needed in damper appli-
cations requiring the crank arm to rotate through the
bottom plane of the actuator. If the bracket is not used in a
replacement application, the damper linkage will have to
be adjusted to the new shaft position.
The motor comes without a crank arm. The crank arm
is included in the Q605 linkage or may be ordered sepa-
rately (see Accessories).
For detailed instructions on the assembly of specific
linkages, refer to the instruction sheet packed with each

3. The motor must be stopped at the end of its stroke
by the limit switch and must not be stalled by the damper

complete its full stroke.

WIRING BOX
WIRING
When used with liquid-tight conduit connectors, the wiring
box provides NEMA 3 weather protection for the motor.
The box also provides knockouts for wiring conduits and
encloses terminals. The wiring box, standard with replace-
ment motors, is required for housing an internal trans-
former, internal auxiliary switches or Series 70 Interface
Modules.
Disconnect power supply before wiring to prevent electri-
cal shock or equipment damage. All wiring must agree with
applicable codes, ordinances, and regulations.
A transformer is required to supply 24
power to the
motor. Make sure that the power requirements stamped on
the motor correspond to the characteristics of the power
supply.

The auxiliary switches in
motors are actu-

motor shaft at the power end of the motor. The settings of
the cams determine the point in motor shaft rotation at
which the auxiliary equipment will be switched on or off.
These cams can be set to actuate switches at any angle
within the stroke of the motor. Also each cam provides a

SERIES 90 CIRCUIT
These motors are designed for use in series 90 propor-
tioning control circuits employing a 135 ohm series 90
controller. Series 90 high or low limit controls or manual
minimum position potentiometers may also be used in the
control circuit.
The potentiometers, one in the controller and one in the
motor, along with resistor network, form a bridge circuit. As
long as the value of the controlled medium remains at the
controller set point, the circuit is balanced, and the motor
does not run.
When the value of the controlled medium changes, the
potentiometer wiper in the controller is moved, which
unbalances the bridge circuit. This unbalance is amplified,
