TOSHIBA

Description and Resolution
This warning can be caused by
the same conditions listed for
ambient overheat. Another
possible cause would be a
problem with the battery module,
which could prevent the unit
from providing backup power.
This warning will occur if the input
voltage drops below the minimum
allowable voltage. If the u nit was
online when the warning occur red it will
transfer to battery backup. After the
backup the output will shutdown. If the
unit was in bypass the output will be
turned off. The unit will reinitialize the
startup sequence if input power returns
to within specified limits.
This warning will occur if the input
voltage exceeds the maximum
allowable voltage. If the u nit was
online when the warning occur red it will
transfer to battery backup (see note 2).
If the unit was in bypass the output will
be turned off. The unit will return to
normal operation if input power returns
to within specified limits.
