The Liebert AC4™ Autochangeover Controller provides autochangeover and autosequence control for
up to four Liebert Mini-Mate2 units within a room. The Liebert AC4 will enable redundant units in an
alarm condition, balance usage and test standby units at programmed intervals. Two common alarm relay
outputs are available. A built-in LCD and RS-232 port for direct PC/terminal connection provides two
options for configuration and monitoring of the product. The Liebert AC4 requires 24VAC input power.
™
The Liebert® AC8 is ideal for coordinated control of systems with redundant units. The Liebert AC8
enables redundant devices during an alarm condition, balances usage of devices and tests standby
devices at programmable intervals. Supports four zones and can use the 4-20mA temperature sensor
(TW420) for temperature staging in each zone. Two programmable output control relays are available for
auxiliary control such as humidity lockout. Emergency power operation input provided for device control
during an emergency. Two common alarm relay outputs are available. A built-in LCD and RS-232 port for
direct PC/terminal connection provides two options for configuration and monitoring of the product.
™
The Liebert ENV-DO interface card provides 16 discrete outputs, corresponding to status and major
alarm conditions of Environmental units. The Liebert ENV-DO-ENCL1 packages one Environmental DO
interface card in its own steel enclosure and the ENV-DO-ENCL2 packages two Environmental DO
interface cards in one enclosure for installation external to the Liebert Mini-Mate2™. The self-contained
kit includes an external 120VAC-to-24VAC power transformer. Wiring harnesses are not provided. Power
and communication wiring is field-provided.

410 Point Leak Detection Sensor detects the presence of conductive liquid using
The Liebert Liqui-tect
a pair of corrosion-resistant, gold-plated probes mounted in a painted, height-adjustable enclosure. Dual
Form-C, dry contact common alarm relays (rated at 24VAC, 3A) signal a leak detected as well as loss of
power and cable fault. The Liebert Liqui-tect 410 requires an external 24VAC or 24VDC power source.
Liebert LT460 Zone Leak Detection Kits include one LT460 sensor, a specified length of LT500-xxY
cable (maximum length is 100 ft [30.5m]) and a corresponding number of hold-down clips. The Liebert
LT460 requires an external 24VAC, 0.12A power source, such as EXT-XFMR or XFMR24.
Liebert SiteScan® is a monitoring solution that gives you decision-making power to effectively manage
the equipment critical to your business.
Liebert SiteScan enables communication from Liebert environmental and power units, as well as many
other pieces of analog or digital equipment, to a front-end software package that provides real-time
status and alarms so you can react quickly to changing situations.
Liebert SiteScan is designed with flexibility for both small systems and large, complex systems such as
those in computer rooms, telecommunications facilities or industrial process control rooms. Contact your
local Vertiv™ representative for assistance with a Liebert SiteScan system.
The NIC-ENCL1 and NIC-ENCL2 package one or two Liebert IntelliSlot® Web/485 Cards with Adapters,
respectively, in one steel enclosure for installation external to the Liebert Mini-Mate2. The Liebert
IntelliSlot Web/485 Card with Adapter provides communication with Liebert Mini-Mate2 via SNMP, HTTP,
RTU Modbus 485 and BACnet IP. The self-contained kit includes an external 120VAC-to-24VAC
transformer as a power source. Wiring harnesses are not provided. Power and communication wiring is
field-provided.
