MAx-305 & MAx-318 Series
MAx-405 Through MAx-419
Series
Two-Position Actuators
General Instructions
Application
For two-position operation of dampers, valves, and
other equipment which require the return to normal
position upon power interruption.
Hazardous location models offer a sturdy cast
aluminum case with bolted cover. They have two 3/4"
pipe tapped openings for joints with rigid metal conduit.
All wiring is brought out to separate terminals for ease
of installation. These factory enclosure and actuator
assemblies are Underwriters Laboratories listed.
Features
• Compatible with most SPST control devices
• Spring return
• 24, 120, 208, and 240 Vac models
• Actuators with part number suffix "-500" are
equipped with SPDT auxiliary switch
• Actuator has a rugged die cast aluminum housing
with two 1/2” conduit openings
• Hazardous location actuator housing has two 3/4"
pipe taped openings for rigid metal conduit
connection
• Oil immersed motor and gear train

INSTALLATION
Inspection
Requirements
Mounting
F-06491-32
Inspect the package for damage. If damaged, notify the appropriate carrier immediately.
If undamaged, open the package and inspect the device for obvious damage. Return damaged
products.
• Job wiring diagrams
• Tools (not provided):
– Digital Volt-ohm Meter (DVM)
– Appropriate screwdriver(s) for cover and mounting screws
– Appropriate drill and drill bit for mounting screws
– Appropriate wrenches for adjustment of damper and valve linkages
• Appropriate accessories
• Mounting screws (not provided)
• Training: Installer must be a qualified, experienced technician
Warning:
• Disconnect the power supply (line power) before installation to prevent electrical shock and
equipment damage.
• Make all connections in accordance with the wiring diagram and in accordance with
national and local electrical codes. Use copper conductors only.
Caution:
• Do not apply power to the unit unless the damper linkage and/or the valve assembly have
been installed.
• Avoid locations where excessive oil, dust, moisture, corrosive fumes or vibration, or an
explosive atmosphere is present. The actuator case is intended primarily to provide a
degree of protection against windblown dust, rain, sleet, and external ice formation (NEMA
Type 4).
Mount the actuator according to the following requirements:
1. Allow a minimum of 6" (152 mm) clearance behind the actuator for access to the wiring
compartment.
2. Locate the actuator in a weather-protected area.
3. To ensure water and weather resistance, install the cover gasket (provided) and use
water-tight conduit fittings.
Dampers
Install the actuator and the damper linkage, so that 180° of actuator shaft rotation drives 90° of
damper shaft rotation, as follows:
Actuator Mounting and Damper Linkage Installation
1. Mount the actuator in an appropriate position near the damper.
Note:
• MA-305 and MA-405 series actuators are not position-sensitive, and in damper applications,
may be mounted in any position. However, the upright position is preferred.
• MA-318, MA-416, MA-418, and MA-419 series actuators must be mounted so that the
output shaft lies in a horizontal position.
• To the extent possible, position the actuator to optimize the length of the damper rod
needed to link it with the damper. A damper rod that is too long is not rigid enough for good
control, and a damper rod that is too short makes it difficult to adjust the linkage.
2. Install crank arms onto the driven shaft and the actuator shaft. Tighten the crank arm on the
driven shaft. Do not tighten the crank arm on the actuator shaft at this time.
3. Install a linkage connector onto the actuator shaft crank arm, at the prick point. Refer to
(Figure-3) and (Figure-4).

MAINTENANCE
Caution: MA-300 series and MA-400 series actuators that are used in applications where they
are energized for extended periods of time must be electrically cycled at least once every six
months to ensure correct operation.
Regular maintenance of the total system is recommended to assure sustained, optimum
performance.
FIELD REPAIR
None. Replace an inoperative actuator with a functional unit.
