Introduction

1.0 INTRODUCTION
The Liebert Intellislot™ Interface for Relay Contacts card
provides contact closures for remote monitoring of alarm
conditions in your Liebert UPS. Delivering On Battery, On
Bypass, Low Battery, Summary Alarm, UPS Fault and On
UPS signals, the easy-to-install card integrates with other
relay contact monitoring systems.
This advanced power-management device is specially
designed to function only in the Liebert Intellislot port of the
following supported UPS units:
• Nfinity™
• Liebert NX™
• PowerSure PSI™

• UPStation GXT™
• UPStation GXT2™

In addition, the RS-232 port on the UPS remains active with
the card installed, allowing more sophisticated monitoring
with Liebert MultiLink™ software.
On supported units, the inverter shut-off command can be
controlled from the computer directly connected to the UPS
(via the factory-installed DB9 connector) and will conserve
battery power after the workstation shutdown is completed.
The Intellislot Interface for Relay Contacts card is rated for
24 VAC/DC at 1A.
