A battery shutdown signal on Pin 4 will NOT cause an immediate shutdown.
A shutdown signal will start a 2-minute shutdown timer. The timer cannot
be stopped. After 2 minutes, the UPS will shutdown.
4.
If the utility returns during the 2-minute timer countdown, the
shutdown timer will continue until the end of 2 minutes and the UPS
will turn OFF. The UPS must remain in OFF for at least 10 seconds
even if AC input power returns before the UPS turns OFF. This serves
to reset and restart the server.
Whether the UPS turns back ON when power is restored depends on the
auto-restart setting: enabled or disabled.
If the auto-restart is disabled, the UPS will not restart after performing the
2-minute shutdown delay.
Pins 5 & 6 - Any-Mode Shutdown
Pin 6 of the 9-pin communication connector is used for “Any-Mode Shutdown”
of the UPS output. This control input may be used in special applications to
disable the UPS output power-both Inverter and Bypass.
The Options tab allows the behavior of the Any-Mode Shutdown feature to be
modified. When the program opens, or the REFRESH button is pressed, the
UPS setting is read by the configuration program and displayed.

WARNING
Note that when this option is selected and the UPS output
is disabled using Pin 6, the UPS output can turn on

WARNING
DO NOT CHANGE THIS OPTION from the factory default
setting unless you are ready to install a normally-closed
connection between Pin 5 & 6. This connection must be
maintained to use the UPS or to use the configuration
program again, including the ability to change the UPS
setting back to the default setting using the configuration
program via a serial communication link.
