Mounting Location

Recommendations:
• Ambient temperature within –40 to 80
• Easy access for viewing the display and programming via the hand programmer.
• An environment suitable to the housing rating and materials of construction.
• Keep the sound path perpendicular to the material surface.
Precautions:
• Avoid proximity to high voltage or current wiring, high voltage or current contacts, and to
variable frequency motor speed controllers.
• Avoid interference to the sound path from obstructions or from the fill path.
The sound path should be:
• perpendicular to the
monitored surface
• clear of rough walls,
seams, rungs, or
other obstructions
• clear of the fill path
