The Liebert PSI is a 2U, line-interactive UPS that may be installed in a rack or used as a tower UPS.
Status indicators on the front of the Liebert PSI display load level, battery level, buck/boost, site-wir-
ing fault, overload, battery status and UPS operation. Controls include a combination On/Alarm
Silence/Manual Self-Diagnostic Test button, an Off button and a Status Change button.
The Liebert PSI has USB, DB-9 (contact closure) and Liebert IntelliSlot
®
ports. The DB-9 and USB
ports provide detailed operating information including voltages, currents, and alarm status to the
host system when used in conjunction with Liebert MultiLink
™
software.
The Liebert PSI is compliant with the Restriction of Hazardous Substances Directive (ROHS), prohib-
iting use of six hazardous materials manufacturing of electronics, including lead-free solder.
