Over the extended ranges of temperature, voltage, and frequency not
covered by normal operating conditions, low frequency and run related
functions are allowed an additional 20% on specification limits. The
degradation shall not be permanent, and upon returning to normal
operating conditions shall be within the specification limits. Non-nor-
mal òRun Modeó operation is 45 hours cumulative life not exceeding a
continuous run time of 10 minutes with a 10 minute òOffó time follow-
ing each successive operating cycle.
