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.

aMAx-31x-x-x-4 and MAx-41x-x-x-4 series actuators provide significantly improved high temperature exposure performance for use in smoke or fire dampers, or combination smoke and fire dampers. Refer to Engineering Information EN-216 (UL 555S), F-27068.
bClass 1, Groups C & D, and Class 2, Groups E, F, and G hazardous locations; refer to EN-56-2.
cModels for hazardous locations are only available as factory-built enclosure/actuator assemblies.
dSee standard actuator part number wiring diagrams for wiring terminations.
