INTRODUCTION  
ENVIRONMENTAL CONTROL  
Your Liebert Little Glass House™ (LGH) will  
provide a secure controlled environment in a  
single factory assembled enclosure. The  
integrated/matched models are designed to  
control the environment and provide smooth  
reliable power so that your sensitive computer  
and network equipment will provide the reliable  
performance you depend upon for your business  
operations.  
The Uninterruptible Air Supply™ (UAS) consists  
of an Environmental Control Module (ECM) and  
a Back-up Cooling Fan. The ECM is normally  
sized to match the capacity of the UPS module  
plus heat transmitted into the LGH. Three ECM  
modules, ECM-42, ECM-62, and ECM-80 are  
available. Air is controlled and circulated within  
the enclosure. Outside (ambient) air is used to  
remove heat from the enclosure through the air  
cooled condenser. Two-speed fans are used to  
provide quiet operation. At rated maximum  
ambient conditions, the temperature inside the  
enclosure will be from 70° to 95°F (21 to 35°C),  
depending on the electronics load. If the internal  
cabinet temperature reaches 100°F (38°C) -- for  
example, during a power failure -- the Back-up  
Cooling Fan operated on UPS battery power will  
flow filtered ambient air through the enclosure.  
The Little Glass House is completely factory  
assembled and tested, ready for you to install  
your equipment and plug the unit into a 120 V~/  
60 Hz or 230 V~/ 50 Hz dedicated outlet. For 60  
Hz  
models,  
the  
required  
power  
receptacle/socket may be 15, 20, or 30 Amps,  
depending on your selected LGH. Models with  
60 Hz ECM-80 uses two input power  
connections, with one 20 Amp plug for the ECM-  
80 and the other plug either 15 or 20 Amps  
depending on the UPS model. For 50 Hz  
models, a power cord is included for connection  
to a customer supplied plug.  
The Back-up Cooling Fan is standard on UAS  
models. All UAS or ECM models require a  
clearance of 12 inches (305 mm) both on top  
and rear of the LGH for proper airflow. The 50  
Hz back-up cooling options have an On/Off (O/I)  
switch located in the inlet channel to the ECM  
condenser coil. This switch should be on during  
normal operation.  
Refer to drawings and tables in this manual for  
dimensions, environmental performance data,  
and input power requirements. Refer to the  
separate UPS manual for UPS performance  
details.  
If environmental control as previously described  
is not required, Forced Air Cooling (FAC) is  
available. Filtered ambient air is drawn through  
the enclosure from the bottom front to the top  
ENCLOSURE  
The enclosure can accommodate shelf mounted  
or rack mounted equipment, on either 19 or 24  
inch punched rails (per EIA-310). The 19 inch  
rack cabinets are 25 inches (635 mm) wide.  
Cabinets with 24 inch racks are 30 inches (765  
mm) wide. The enclosures can be nominal 72  
or 78 inches (1830 or 1980 mm) high, and 34 or  
38 inches (865 or 965 mm) deep. The unit is  
mounted on casters and leveling feet. Interior  
insulation is provided in models with  
Environmental Control Module (ECM) cooling.  
rear.  
A two-speed fan is controlled by a  
thermostat factory set at 80°F (27°C), which  
measures air entering the unit. The two-speed  
fan design provides quiet low-speed operation  
below the thermostat set point. A single fan  
(nominally rated at 190 CFM - 323 CMH) or dual  
fans (nominally rated at 360 CFM - 611 CMH)  
can be provided. A clearance of 12 inches (305  
mm) is required both on top and rear of the LGH  
for FAC models.  
A solid panel (metal) front door is standard. A  
smoked plastic front window is available to  
maintain enclosure security while allowing you to  
monitor equipment status.  
The rear door  
provides convenient access to customer wiring.  
Two horizontal cable entrance raceways are

INSTALLATION CONNECTIONS  
The Little Glass House is a self-contained unit.  
The only required connection is for electric  
power. For 60 Hz models, the power cord is 9  
(2.7 m) feet long and has a NEMA 120 V~ plug,  
sized for current (Amps) based on equipment  
specified when ordered. For 50 Hz models, a  
power cord is included for connection to a  
customer supplied plug. The 60 Hz ECM-80  
model uses two input power connections, with  
one 20 Amp plug for the ECM-80 and the other  
plug either 15 or 20 Amps depending on the  
UPS model. Refer to table on page 11. The  
LGH and its protected equipment should be on a  
dedicated circuit and circuit breaker.  
The optional SiteNet™ Integrator is a separate  
rackmount unit which communicates status of  
the UPS and Little Glass House (including  
temperature/humidity and several contact  
closures) in SNMP protocol to a network  
management system.  
No plumbing connections are required as ECM  
condensate is evaporated into the heat rejection  
airstream. A condensate drain tube (3/8 inch  
O.D. copper) is provided with ECM, but a  
customer connection is not necessary. The  
drain connection may need to be used in  
exceptional situations, such as if a door is left  
open for longer than 15 minutes while the ECM  
is operating.  
Do not defeat ground/earth connections  
between the utility/mains outlet and the Little  
Glass House. All plug receptacles/sockets in  
the vicinity of where the LGH will be used must  
be a ground/earth type and grounded/earthed  
with an insulated ground/earth conductor of  
identical size, insulation material, and thickness  
INSTALLING CUSTOMER EQUIPMENT  
The Little Glass House can accommodate rack  
mounted or freestanding computer and network

larger UPS can be supplied for longer battery  
time. For 60 Hz units without a UPS, the  
customer specifies maximum Amp load to  
determine proper NEMA power plug rating.  
NOTE: To charge the UPS batteries before  
using the unit, you can apply power to the UPS  
module while you are installing your equipment.  
Install your critical equipment in the Little Glass  
House. Use the two vertical channels at the rear  
of the unit for routing customer wiring. Power  
and communication wiring should be kept  
separate as much as possible.  
The 60Hz Environmental Control Module has a  
lighted power switch. The power switch for the  
50 Hz models is the circuit breaker “B" on the  
electric service assembly. ECM temperature  
and capacity controls, including hot gas bypass,  
are factory set. The FAC models have a  
temperature switch factory set at 80°F (27°C),  
which measures air entering the unit. The front  
air filter requires periodic cleaning.  
CAUTION: To avoid excessive condensation,  
turn off the Environmental Control Module any  
time an LGH door will be open for more than 15  
minutes.  
The optional power strip includes a circuit  
breaker. The 60 Hz model includes 10 5-15R 15  
Amp, 120 V~ receptacles/sockets. The 50 Hz  
model includes 10 CEE22 (IEC320) 10 Amp,  
250 V~ receptacles/sockets. The power strip is  
protected by the UPS if a UPS is included. As  
viewed from the rear, the ten power outlets are  
on the right side. Power wiring is intended to be  
routed on the right. Communication and control  
wiring should be routed to the left side.  
The UPS module has user friendly controls and  
indicators. Refer to separate UPS manual for  
details of UPS operation and LED indicators.

enclosure through the air cooled condenser. The  
outside air is drawn through a louver and filter at  
the bottom front of the unit and is discharged at  
the rear (near the bottom).  
The lighted ON/OFF switch is located inside the  
front door, on the left side of the electrical panel  
on 60 Hz models. For 50 Hz models, use circuit  
breaker “B” of electrical service assembly for  
ECM On/Off.  
UNINTERRUPTIBLE POWER SUPPLY (UPS)  
The Little Glass House may be supplied with  
one of several Liebert UPS units, or with no  
UPS. For integrated/matched models, the UPS  
and ECM are normally sized with matched  
capacities. A larger UPS can be supplied for  
more battery time, but the connected electronics  
load should not exceed the ECM rating.  
At rated maximum ambient conditions, the  
temperature inside the enclosure will be from  
70° to 95°F (21 to 35°C), depending on the  
electronics load. The two speed fans are factory  
set to operate at the lower speed for quiet  
operation when the outside air entering the

modulates automatically to match compressor  
capacity to the present load. Consult factory if  
adjustment is desired.  
In UAS systems, during an enclosure high  
temperature condition (100°F - 38°C) a separate  
Back-up Cooling Fan operated on UPS battery  
power (if included) will use filtered ambient air to  
cool the enclosure. This would occur only  
during a power failure or an Environmental  
Control Module failure. To annunciate a high  
temp condition, an alarm beeper sounds and the  
alarm contact closes (press Alarm Silence  
switch to turn off beeper). Outside air is drawn  
through a louver and filter at the bottom front of  
the unit and is discharged at the rear (near the  
top).  
The SiteNet Integrator is powered by one or two  
externally mounted power supplies. One is  
standard, the second is optional. These power  
supplies provide the 9VDC required to power the  
Integrator module. One supply will be plugged  
into the UPS or the UPS outlet strip located in  
the rear hinge side of the cabinet. The output  
cable is plugged into the SiteNet Integrator  
Power Supply Main input receptacle/socket. The  
(optional) second supply will be plugged into the  
electrical service power inlet in the lower rear of  
the LGH cabinet. The supply's output cable is  
plugged into the SiteNet Integrator Power  
Supply Aux input receptacle/socket.

rear of the ECM. A two-conductor control cable  
is connected between the power supply terminal  
strips marked "Close to Energize Relay R1" and  
the Relay Output K1 terminal strip on the rear of  
the SiteNet Integrator. When the relay output  
contacts on the SiteNet Integrator close, the  
relay in the power supply is energized closing  
the normally open contacts and shorting  
between terminals 37 & 38 in the rear of the  
ECM. This will allow power to be applied to the  
ECM and cause the ECM to begin operation if  
the ECM On/Off switch is in the On position.  
Consequently, de-energizing the relay will allow  
the ECM to be turned off remotely by the SiteNet  
Integrator.  
An optional UPS status communication cable is  
available that allows transmission of information  
between the UPS and the SiteNet Integrator.  
This cable will plug into the 25 pin D Type  
connector on the rear of the UPS marked DB-  
25P. The opposite end of the cable in plugged  
into the 9 pin D Type receptacle on the rear of  
the SiteNet Integrator marked UPS RS-232 DB-  
9P.  
SENSOR OPTIONS  
Door Ajar -- This option consists of two normally  
open switches that are mounted to the cabinet  
front and rear frame supports. The switches will  
indicate by the position of the doors (opened or  
closed) as determined by the status of the dry-  
contact inputs to which they are connected on  
the rear of the SiteNet Integrator.  
Smoke Detector Option -- A four-wire smoke  
detector with normally open contacts, heat  
sensor and sounder alarm is mounted in the top  
of the LGH cabinet. The smoke detector is  
power by a 24VDC power supply (*) mounted in  
the frame channel of the LGH cabinet. The  
power supply is normally powered from the UPS  
(if available), but may be powered from  
utility/mains by customer discretion. Power to  
the smoke detector is supplied by a two-  
conductor cable between the power supply and  
the smoke detector. A second two-conductor  
cable connects between the smoke detector and  
the Integrator dry-contact inputs. If smoke,  
flame, or high temperature change are detected,  
the normally open contacts of the smoke  
detector will close to provide alarm status to the  
Integrator. The smoke detector sounder alarm  
will also activate. This alarm can be silenced  
only by removing power from the smoke  
detector. This is accomplished by unplugging  
the smoke detector power supply.  
Temperature and Humidity Sensors (Internal  
and External) -- The sensors allow monitoring  
of temperature and humidity status by the  
SiteNet Integrator. The internal option is for  
installation inside the LGH cabinet and is  
supplied with a 12 foot (3.6 m) cord for  
connection between the temperature/humidity  
sensor and the SiteNet Integrator. Refer to the  
connection diagram for wiring specifics. The  
external option is supplied with a 30 foot (0.1 m)  
cord for monitoring of temperature humidity  
status outside the LGH cabinet. The sensor and  
connections for both options are identical.  
Water Detect -- The water detect option  
includes a Liquitect (LT-400S) dry contact  
sensor mounted in the bottom of the LGH  
cabinet. The sensor is powered by a 24 VDC  
power supply mounted in the frame channel of  
the LGH cabinet. (Multiple options may share  
this same general power supply. The supply is  
rated for 1.6 Amps at 24 VDC). The water  
detector is connected to the dry-contact input on  
the rear of the SiteNet Integrator by a 30 foot  
two-conductor cable. The detector may be  
relocated outside the LGH cabinet by user  
discretion for external water detection.  
*The smoke detector power supply is a general purpose  
supply that may be used to power any option requiring 24  
VDC. Multiple options may share the same supply. The  
supply is rated for 1.6 Amps at 24 VDC.  
All the above options are available factory  
installed with the order. The options are also  
available for field installation. Field installed  
options are shipped as kits containing the  
sensors with appropriate mounting hardware,  
Remote ECM On-Off Control -- This option  
allows on-off control of the ECM by the SiteNet  
Integrator. It consists of a 24 VDC Power  
Supply with Control Relay that is mounted in the  
frame channel of the LGH cabinet. The 24 VDC  
power supply may also be used to power other  
options. A black SJ two-conductor (black & red)

MAINTENANCE  
CAUTION: To avoid tipping the unit when it is  
UPS REPLACEMENT  
being moved, push slowly on the lower part of  
the enclosure. After customer equipment is  
installed, the Little Glass House™ may have a  
high center of gravIty.  
To remove the UPS for factory repairs:  
-Turn off power. Unplug UPS from receptacle  
inside rear of the Little Glass House.  
-Unplug the power strip, ECM or FAC controls,  
and any other equipment plugged into the UPS.  
FILTER CLEANING  
NOTE: Inspect the air filter periodically to  
determine the necessary cleaning interval based  
on conditions at your installation.  
-Disconnect any optional communication cables.  
-Remove screws retaining the UPS.  
-Remove the UPS from the front of the LGH.  
-Install the replacement UPS.  
If the air filter becomes dirty and clogged, the  
alarm contact closes (no beeper alarm is  
sounded). The filter is behind the louver at the  
bottom of the front door. Remove two screws,  
pull up the filter, clean with mild soapy water,  
rinse, dry, and replace.

TO REMOVE THE ECM FOR FACTORY  
REPAIRS:  
-Turn off power. Unplug Environmental Control  
Module from receptacle inside rear of the Little  
Glass House.  
-Remove the screws retaining the access plate  
at top left rear of ECM. Remove the plate and  
tuck the ECM power cord and plug inside the  
opening to allow the ECM to pass beneath the  
UPS or mounted shelves. For models including  
a UPS, do not replace this access panel until  
after ECM has been removed.  
-Models containing a 60 Hz ECM80 require the  
removal of the plug from the ECM power cord.  
Once removed the power cord strain relief may  
be loosened to allow the power cord to slide  
through when the ECM is withdrawn from the  
cabinet.  
Observe wiring polarity when  
reinstalling the plug on the replacement unit.  
-If connected, remove customer wiring to ECM  
compressor power contact and/or remote  
shutdown/startup contact.  
-Remove four screws retaining the front  
electrical panel. Pivot panel to the left. Cables  
are long enough to move the box out of the way  
so the Environmental Control Module can be  
pulled forward after removing four rack mount  
screws.  
-Replace cable access cover on ECM. Package  
unit for return to Liebert.  
-Install the replacement ECM.
