M9208-100 Remote Mounting Kit Installation Instructions 3
Note: If the actuator is in a difficult-to-reach location,
adjust the auxiliary switches and stroke settings before
continuing with the installation. Adjustable stroke
instructions are detailed in the section Setup and
Adjustments.
Mounting Positions
The M9208-100 Remote Mounting Kit allows the
installer to select spring-return direction as required by
the application. The label on the actuator indicates the
spring-return direction.
To set the spring-return direction of the actuator when
mounted in a bracket, rotate the actuator as required.
Choose CW or CCW spring-return direction by flipping
the actuator over.
Installing the Remote Mounting Kit
See Figure 4 for the hole mounting pattern of the
mounting bracket. The hole pattern locates the actuator
crankarm assembly with respect to the drive blade,
jackshaft, or crankarm to be driven.
To install the mounting bracket:
1. Locate the mounting bracket in the desired
position.
2. Use a center punch to mark the hole locations for
the bracket in the duct or damper frame. See
Figure 4.
3. Fasten the mounting bracket by drilling the
No. 10-16 x 0.75 in. self-tapping screws through
the holes in the mounting bracket and into the duct
or damper frame.
Note: Ensure that the orientation of the actuator is
correct with respect to the application. Observe the
spring-return direction of the actuator during the
installation.
4. Using two M5 cap screws, secure the actuator to
the mounting bracket as shown in Figure 2 and
Figure 3. The raised buttons on the mounting
bracket are used for anti-rotation of the cap screw,
allowing installation with only one wrench. Install
the M5 nylon insert hex nuts using the
recommended torque of 1.7 to 2.3 N·m (15 to
20 lb·in.).
5. Install the crankarm and washer using the M5 cap
screw and nylon insert hex nut, as shown in
Figure 5. The raised buttons on the crankarm are
used for anti-rotation of the cap screw, allowing
installation with only one wrench. Install the M5
nylon insert hex nut using the recommended
torque of 1.7 to 2.3 N·m (15 to 20 lb·in.).
Note: Proper orientation of the crankarm is critical for
correct operation. Observe the full open and close
positions of the actuator, and ensure that the crankarm
does not interfere with the mounting surface.
6. Placing the washer in the orientation shown in
Figure 6 allows for use of the adjustable end-stop if
desired.
IMPORTANT: Remotely mounted M9208 Series
actuators can develop high linear and rotational
forces. Confirm that mounting surfaces are
sufficiently rigid and strong before installing the
remote mounting kit.
IMPORTANT: All user adjustable features of the
actuator are accessible when mounted in the
bracket. Depending on the orientation and model
used, the bracket may cover up the scale on the
label for the adjustable switch.
