6.2.2 Battery Mode Shutdown Via Pins 4 & 5
While the UPS is operating on battery, a 5-12VDC signal for 2 seconds or longer is required to signal a
shutdown. Signals for less than 2 seconds are ignored.
After Pin 4 receives the shutdown signal, a 2-minute shutdown timer begins a countdown. The shutdown
timer cannot be stopped: If mains power returns during the 2-minute countdown, the shutdown timer
continues until the end of 2 minutes and the UPS turns Off. The UPS will restart 10 seconds after mains
power returns.
6.3 Network Surge Protection Connectors
Network (in and out) connectors on the rear of the UPS provide transient voltage surge suppression
(TVSS) for network devices.
6.4 UPS Communications
The Liebert PSI XR is equipped with a Liebert IntelliSlot
®
port to provide advanced communication and
monitoring options.
Liebert’s shutdown software continually monitors the UPS and can shut down your computer or server via
USB and RS-232 in the event of an extended power failure.
The Liebert IS-WEBRT3 provides SNMP and Web-based monitoring and control of the UPS across the
network.
NOTE: The USB and Contact Closure communications operate in parallel. Using the Liebert IS-WEBRT3
disables the serial communications of the DB-9.
6.5 UPS Inverter/Transfer Voltage Configurations
A two-pin DIP switch on the rear of the Liebert PSI XR permits setting the UPS to operate at nominal
voltages of 220V, 230V or 240V. This feature will change the high and low points at which the UPS
switches to battery power. It also will change the UPS’ output voltage when the UPS is operating in battery
mode. The factory default setting is 230 VAC.
