Enclosures
Installation Instructions
Applications
The M9000-310 and M9000-320 Weather Shield
Enclosures are cost-effective and durable weather
shields designed to provide a degree of protection for a
single Johnson Controls® M9000 Series Electric
Actuator used in either control damper or iron flanged
valve applications. These weather shield enclosures
are manufactured to National Electrical Manufacturers’
Association (NEMA) 3R specifications and protect the
electric actuator from corrosion, rain, freezing rain,
sleet, and snow. The enclosure can be mounted
indoors or outdoors; however, it may not prevent
externally formed ice from restricting the motion of the
rotary shaft.
Each enclosure is constructed of impact-grade ABS
plastic that provides excellent impact resistance. The
cover features ultraviolet inhibitors that extend service
life by preventing the cover from becoming brittle or
damaged by the sun or other environmental elements.
The transparent cover provides an unobstructed view
of the electric actuator without having to disassemble
the enclosure. An appliance cord enables installation of
control wiring, and a form-fitting seal prevents water or
moisture from entering the unit and damaging the
actuator.
IMPORTANT: The M9000-310 and M9000-320
Weather Shield Enclosures only provide protection
for the Johnson Controls M9000 Series Electric
Actuator used in control damper and iron flanged
valve applications. To ensure proper operation,
check that all associated equipment used in the
application is suitable for the surrounding
environment.
