CAUTION:
If your test sample is energized, it may be capable of raising the workspace
temperature beyond safe limits. This could occur if your test sample exceeds
the live load rating of the chamber or if the chamber’s refrigeration system
fails. This chamber has a set of contacts that can be used to remove power to
your test sample if the Limit Controller’s temperature limits are exceeded.

CAUTION:
To prevent damage to your test sample and the chamber’s compressors, do not
exceed the live load rating of the chamber.
