*1 Refer to the graph of the previous page for contact capacity.
When using the UPS monitoring function (using the above contact signal)
preinstalled in the following OS, contact your maintenance staff, since the dedicated
RS-232C cable for contact signal which corresponds to each OS is needed
separately. For more detail on the UPS monitoring function preinstalled in each OS,
refer to an instructions manual, an on-line manual, etc. of each OS.

*2 In the case of Windows 2000 and XP, although the shutdown of OS can be
performed during the power failure, a subsequent UPS automatic shutdown cannot
be performed.
