6.2. Over Temperature Shutdown
If configured, the Application may trigger the Shutdown Procedure when the UPS is
about to shut down by its Over Temperature protection.
Notes:
1. An Over Temperature failure is a rare event, triggered by a combination of abnormal
conditions such as above spec ambient temperature, a prolong overload, a blocked
cooling air path, a failed cooling fan, etc. The Over Temp threshold is set sufficiently
high such that it eliminates false trips, but once it does trip, in order to prevent
irreversible damage, the UPS will shut itself off within 3 minutes.
2. If the system cannot tolerate an un-orderly shutdown even in the unlikely event of an
Over temp failure, then the settings of "Windows Shutdown Delay" + the time it
actually takes your PC to shutdown should be shorter than 3 minutes. If this is
impossible, you may need to disable the Over Temp protection by driving the UPS to
Battle Mode (see the UPS User Manual "M359_SNMP_UM"). But caution!!! When
the in Battle Mode, an Over Temp failure may result in an irreversible damage to
the UPS!!!
If the Application detects that the UPS is about to shutdown due to an Over
Temperature (and the Over Temperature Shutdown is enabled), the battery icon
will change to Red and a message balloon will inform the user about the imminent
shutdown:
And the following Windows shutdown window will be displayed:
