Environmental Specifications
Certain components of a PM controller may run at temperatures exceeding 120
°
Degrees Fahrenheit. This is normal for a PM controller and does not indicate a defect.
The recommended operating temperature for all PM controllers is -25 to +85
°
C. This
temperature rating is based on temperature specifications of the components used to
build a PM controller and is not based on actual testing. We have speculated that PM
controllers may be able to withstand lower temperatures due to the fact that PM
controllers tend to have hot components in critical areas of the design.
Break-Away Tabs
Physically, most MirC controllers are actually 2 sizes. When you receive your
MirC, the unusual shape and size ensures the MirC can fit into a standard
enclosure. Optionally, you can make the controller smaller by breaking away the
out tabs. Break Away tabs are useful in applications where space may be a
concern. This allows your MirC to offer the same functionality in the smallest
possible profile. Break Away tabs are unique to the NCD product line and are a
standard option for most devices released in 2010 and later.
Before breaking the tabs on your controller, please be advised that your MirC
controller will not be returnable for refund or credit if the Break Away Tabs have
been removed.
To break away the tabs, gently but firmly grab each break-away tab with a pair of
pliers and bend the tab back and forth until it breads away from the main circuit
board. This will NOT damage the controller in any way.
Breaking the Tabs from a controller DOES NOT VOID the warranty. Please see
NCD return policy if you would like more information on the policies that
apply to Surface Mount devices.
