Note 1: See the graph on the previous page for contact capacity.
When using the UPS monitoring function (using the above contact signal) pre
installed in the following OS, contact your maintenance staff, since the dedicated
cable for contact signal which corresponds to each OS is needed separately. For
more detail on the UPS monitoring function pre installed in each OS, refer to an
instructions manual, an on-line manual, etc. of each OS.
Windows NT/2000/XP: FiFH/WS9 (dedicated contact signal cable)
Note 2: Windows 2000 and XP permit shutdown of the OS on occurrence of
interruption of power supply, and UPS automatic shutdown thereafter is not feasible.
Note 3: Dedicated RS-232C communication cable is required elsewhere for
execution of RS-232C serial communication. Please contact the in-charge
maintenance staff.
