11.2 Pin 4 - Remote Shutdown on Battery
1. This pin is functional only when the UPS is in battery mode. If the UPS is being powered by the
utility, Pin 4 will ignore any signal on this pin.
2. Pin 4 requires a 5-12 VDC signal to shutdown. This normally comes form the serial port using
Liebert’s contact closure cable. It cannot be used with just a contact closure unless the relay is
used to switch a voltage source. A 5-12 VDC signal for 1.5 seconds or greater is required to signal
a shutdown. Signals for less than 1.5 seconds will be ignored. After Pin 4 receives a shutdown
signal for 1.5 seconds, the command cannot be canceled.
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 shutdown 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.
11.3 UPS Intelligent Communications
The UPStation GXT2-6000RT208 is equipped with an Intellislot ® port to provide advanced communi-
cation and monitoring options.
Liebert’s MultiLink software continually monitors the UPS and can shut down your computer or
server in the event of an extended power failure.
MultiLink can also be configured for use without the serial cable when the Intellislot SNMP/Web card
is installed in the UPS. Additionally, MultiLink can be configured to coordinate shutdown across the
network with other computers running MultiLink when you purchase a MultiLink License Kit. For
more information about the Intellislot SNMP/Web Card and MultiLink License Kits, visit our Web
site ( www.liebert.com ) or contact your local dealer or Liebert representative.
Several option cards are available for use in the Intellislot port of the UPStation GXT2-6000RT208
The Intellislot SNMP/Web Card provides SNMP and Web-based monitoring and control of the UPS
across the network.
The Intellislot MultiPort 4 Card allows you to install MultiLink software on four computers and coor-
dinate shutdown in the event of a power failure.
The Intellislot Relay Card provides dry contact relay outputs for custom wired applications and deliv-
ers support for built-in shutdown for AS/400 systems.

CAUTION
To maintain safety (SELV) barriers and for electromagnetic compatibility, signal cables
should be segregated and run separate from all other power cables, where applicable.
