3.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 shut down.

4.If the utility returns during the 2-minute timer countdown, the shut- down timer will continue until the end of 2 minutes and the UPS will turn OFF. The UPS must remain 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

1.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 spe- cial applications to disable the UPS output power—both Inverter and Bypass.

2.The Options tab allows the behavior of the Any-Mode Shutdown fea- ture to be modified. When the program opens, or the REFRESH but- ton is pressed, the UPS setting is read by the configuration program and displayed.

Auto-Enable Output

! WARNING

Note that when this option is selected and the UPS output is disabled using Pin 6, the UPS output can turn on automatically and without warning if the Pin 6 connection is changed.

Pin 6 Logic

! WARNING

DO NOT CHANGE THIS OPTION from the factory default setting unless you are ready to install a normally-closed connection between Pins 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.

If version 1.6 (or later) is used with an earlier GXT 2U model (with an ear- lier UPS firmware version), the Any-Mode Shutdown features cannot be changed.
