Mechanical:
Anti-Rotation Bracket,
Standard 9" long x 13/16" wide (229 x 21 mm), included with the actuator.
Optional Order AM-752 (4" long x 1-11/16" wide) for mounting the actuator in narrow
spaces.
Universal Mounting Clamps, Two clamps are required for all mounting configurations.
Standard 3/8" to 1/2" (10 to 13 mm) round and square shaft mounting clamps are
included with the actuator.
Optional Order AM-753 for 5/8" (16 mm) square and 3/4" to 1" (19 to 25 mm) round
damper shafts, two per package.
Minimum Damper Shaft Length,
Standard Damper shaft must be at least 4-5/8" (117 mm) long for standard mounting.
Optional Shorter than standard length shafts require the AM-676 shaft extension
(order separately).
Position Indicator, Scale numbered from 0 to 95°, provided for position indication.
Nominal Damper Area, Actuator sizing should be done in accordance with damper
manufacturer’s specifications.
Direction of Rotation, Clockwise or counterclockwise rotation determined by actuator
mounting. The zero (0) position on the position indicator is the normal or spring return
position.
