UPS LAN Shutdown Signal Operation

When the UPS stop signal is sent to the UPS through pin 2 and 3 of the external contact interface, it is possible to
automatically reset the following operating systems (OS), which can automatically implement the shutdown function and
restart the operation: Windows NT, IBM OS/2 LAN server, LANtastic
Parameter 646 – UPS Shutdown by LAN Input Signal Enabled/Disabled
Parameter 647 – UPS Shutdown by LAN Signal Permitted Time Window (Adjustable)
With the UPS Shutdown by LAN Signal function enabled, when line power fails and the UPS goes to backup the LAN will
shutdown even if the UPS returns to normal mode during the shutdown process.
LAN shutdown can take several minutes. The UPS Shutdown by LAN Signal function has a companion UPS Shutdown
by LAN Signal Permitted Time Window parameter that can be set to allow sufficient time to complete the LAN shutdown
process (default: 10 minutes) even if line power is restored during LAN shutdown.
LAN shutdown is treated as a restart after battery shutdown. The restart of the LAN will be determined by the Restart After
Battery Shutdown timer.
Connect only the UPS stop signal to the external contact interface for automatic processing so that the UPS output will not
be turned off by mistake.
If the computer is started/restarted within 10 minutes after the recovery from a power failure, the power supply may
be reset while the computer is restarting.
