LIEBERT LIQUI-TECT® 410
Point Leak Detection Sensor
Product Specification Sheet
Description
The Liebert Liqui-tect 410 (LT410) provides a single-point detection
of leaks. The point detection sensor has two gold-plated sensing
probes to prevent corrosion resistance and to provide accurate
readings. The LT410 constantly monitors points for leaks, internal
faults and power failures and warns of any abnormal conditions.
Mounting brackets allow for sensor height adjustment and leveling.
The LT410 is the ideal solution for sensing leaks under a raised
computer floor or air conditioning drip pans. Two independent
outputs provide added flexibility with the capacity to signal both a
local alarm panel and a remote building management system or
external equipment, such as motorized water shut-off valves.
The LT410 is also ideally suited for the following:

LIEBERT MC
PREMIUM EFFICIENCY CONTROL
STANDARD FEATURES
COIL
Liebert microchannel coils are all‐aluminum construction. Tubes are created by extruding small parallel refrigerant flow paths into
aluminum. Full‐depth louvered aluminum fins fill spaces between the tubes. Tubes, fins and aluminum headers are oven‐brazed to
form a complete refrigerant‐to‐air heat exchange coil. Baffles are used in the headers to separate one coil slab into multiple passes
as needed. Coils are factory leak tested at a minimum of 300 PSIG and dehydrated. Copper stub pipes are electric resistance welded
to aluminum coils and joints are protected with polyolefin to seal joint from environmental corrosive elements. Hot gas and liquid
lines are brazed to the stub pipes with spun closed ends for customer piping connections. Coil pipe assembles are filled and sealed
with a nitrogen holding charge for shipment. One coil is used per fan assembly.
FAN/MOTOR ASSEMBLY The fan/motor assembly is complete with external rotor motor, fan blades and fan/finger guard. Fan blades are
constructed of stamped aluminum or steel extrusion coated with PP plastic. Fan guards are heavy gauge, close meshed, steel wire,
coated with a black corrosion resistant finish. Fan terminal blocks located on the top of the fan guard with IP54 protection class.
Fans are factory balanced and tested before shipment.
Fan Motors Fan motors are specifically designed for variable speed and have ball bearings. The EC fans provide internal overload
protection through the built‐in electronics. Each EC fan motor has built‐in controller and communication module, linked via RS485
communication wire to each fan and the Premium Control Board. This allows each fan to receive and respond to precise fan speed
inputs from the Premium control board..
PREMIUM EFFICIENCY FAN CONTROL The Liebert premium efficiency condenser control system is complete with control board, EC fan
motor(s),refrigerant‐pressure transducer(s), refrigerant‐temperature thermistor(s), ambient‐temperature thermistor, and motor
overload protection in the factory wired control panel. The control board maintains EC fans on the same circuit to the same speed
in order to maintain refrigerant head pressure. The control board receives a run signal from the compressor of the indoor unit via
field‐supplied low voltage interlock wires or with optional, field‐supplied CANBUS communication wires from the indoor unit iCOM.
The system head pressure can be maintained to a minimum ambient temperature of 0 °F (‐18 °C).
HOUSING The condenser housing is constructed of bright aluminum sheet and divided into individual fan sections by full width baffles. Internal
structural support members, including coil support frame, are galvanized steel for strength and corrosion resistance. Panel doors
are provided on two sides of each coil/fan section to provide for coil cleaning. Aluminum legs are provided with rigging holes for
hoisting the unit into position.
UNIT DISCONNECT SWITCH Locking unit disconnect switch is factory installed and wired in attached condenser control section.
OPTIONAL FEATURES
LIEBERT LEE‐TEMP LOW AMBIENT CONTROL Lee‐Temp receiver kits can be added to achieve head pressure control down to minimum ambient
temperatures of ‐30 °F (‐34 °C). The premium efficiency fan control when used with the Liebert Lee‐Temp receiver kits runs the
fan(s) at lower speeds during cold temperatures saving fan energy.
COMMUNICATION The Premium Efficiency Control system provides future communication links with the iCOM control of the indoor Liebert
precision air conditioner. The communication link allows for condenser alarm condition communication to iCOM, communication of
other measurable items on the condenser, and future condenser/fan control features to improve efficiency, sound and wintertime
operation based on iCOM programming.

 5C is the CANbus “DEVICE ADDRESS DIP SWITCH”. CANbus cable not by Liebert. See Note 2 (below).
6) Remote unit shutdown – Replace exiting jumper between terminals TB38-1 and TB38-2 with field supplied normally closed
switch having a minimum 75VA 24VAC rating. Use field supplied Class 1 wiring. (This is an optional feature that may be owner
specified.)
7) Alarm terminal connections –
a. Common Alarm Relay indicates when any type of alarm occurs. TB74-1 is common, TB74-2 is normally open, and
TB74-3 is normally closed. 1 Amp 24VAC is the maximum load. Use Class 1 field supplied wiring.
b. Shutdown Alarm Relay indicates when condenser loses power, or when a critical alarm has occurred that shuts down
the condenser unit. TB74-4 is common, TB74-5 is normally open, and TB74-6 is normally closed. 1 Amp 24VAC is the
maximum load. Use Class 1 field supplied wiring.
8) Indoor unit interlock and SPD alarm terminals –
a. On any call for compressor operation, normally open contact is closed across terminals 70 & 71 for Circuit 1, and
normally open contact is closed across terminals 70 & 230 for Circuit 2 from indoor room unit.
b. During SPD alarm, normally open contact is closed across terminals 12 & 13. SPD is an optional device.
9) CANbus shield terminal – Terminal for field connection of the CANbus field supplied cables. Shield of CANbus field supplied
cables must not be connected to ground.
10) Primary low voltage entrance – One 7/8” (22.2mm) diameter knockout that is free for customer low voltage wiring.
11) SPD entrance – One 7/8” (22.2mm) diameter knockout hole located at the bottom of the enclosure. High voltage surge
protective device (SPD) is optional.
NOTES:
1. Refer to specification sheet for unit voltage rating, full load amp, and wire size amp ratings.
2. The CANbus wiring is field supplied and must be:
a)
shielded
b) 22-18AWG stranded tinned copper,
c) twisted pair (minimum 8 twists per foot),
d) low capacitance (15pf/ft or less),
e) plenum rated(NEC type CMP) if required by local codes,
f) UV and moisture resistant or run within conduit once in an outdoor environment, and
g) must be temperature and voltage rated for conditions present.
h) Examples: Belden part number 89207(plenum rated) or Alpha Wire part number 6454 (UV resistant outdoor rated)
category 5, 5e or higher.
3. Do not run the CANbus cable in the same conduit, raceway, or chase as high voltage.
4. For CANbus network lengths greater than 350ft(107m), contact Liebert factory.
5. All wiring must be sized and selected for insulation case per NEC and other local codes.
