INTRODUCTION

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 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 ECM80 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.

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.

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.

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 provided. An optional internal cable management raceway (vertical) is available. Both doors have a key lock and a four point latch.

ENVIRONMENTAL CONTROL

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 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.

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 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.

UPS SUPPORT

The integrated/matched models include an uninterruptible power supply (UPS) module to provide surge suppression, regulated voltage and frequency, and battery backed operating time. This will allow you to perform a controlled computer shutdown in the event of a utility/mains power failure. The UPS supplied is a rackmount model factory installed in the rack rails and supported by brackets. UPS models available include the on-line Liebert UPStation GXT in 1000, 1500, or 2000 VA capacity. Refer to the separate UPS manual for more details.

EQUIPMENT MOUNTING OPTIONS

Optional equipment mounting hardware is available including a fixed shelf, a pullout shelf, 19 inch to 24 inch rack rail adapters, threaded adapters, adjustable position rack rails and Compaq® adapters. Each optional kit is supplied with installation hardware.

CLUSTERED CONFIGURATIONS

For applications requiring more than one enclosure, an optional Cluster Enclosure is available. In addition to providing more space for electronic equipment, this configuration allows cabinets to be connected side-by-side so that an ECM, FAC, or UPS can serve more than one cabinet. Refer to separate installation instructions provided with the cluster cabinet.

HEAT REJECTION DUCT

For applications in confined spaces (equipment rooms or closets), an optional Heat Rejection Duct is available to connect the Little Glass House to a ducted ventilation system. Refer to drawing on page 19 in this manual for details.

The unit can be rolled forward on casters for easy access to Liebert and customer wiring at the rear of the unit. To open the front door, clearance required depends on the size of your unit. No side clearance is needed.

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.

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 to the grounded/earthed and ungrounded/earthed supply conductors which is grounded/earthed to ground/earth at the service equipment or separately derived source.

NOTE: The utility/mains output must have the neutral and ground/earth bonded, per the National Electrical Code, to prevent damage to the UPS. Damage related to faulty utility/mains wiring is not covered by Liebert warranty.

Contacts are provided to annunciate two alarms: High Temperature (100°F - 38°C internal, Back-

up Cooling Fan operating) and Dirty Air Filter (filter is clogged and requires cleaning). Customer connection is two compression lug terminals inside the rear of the unit. These normally open contacts are rated for 40 milliAmps at 30 volts maximum (Class 2 wiring).

A contact is provided on the rear of the ECM to indicate power to the compressor (Compressor on/off). This normally open contact is rated for

0.5 Amp at 120 V~.

A control contact is provided inside the ECM (under access plate at top left rear) for remote shutdown/ startup. To use, replace jumper on 37 and 38 with a normally open non-powered switch, rated for 5 Amps at 120 V~.

To allow communications between the UPS and a LAN server or other computer system, the available UPStation GXT is equipped with an RS-232 interface port. Other UPS communication options are available, including SNMP. Refer to the separate UPS manual for details.

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.

INSTALLING CUSTOMER EQUIPMENT

The Little Glass House can accommodate rack mounted or freestanding computer and network equipment. The unit contains 19 or 24 inch punched rack rails (per EIA 310), depending on model selected. Rack rails are provided at the front and rear of the enclosure. Mounting hardware available from your Liebert representative includes a fixed shelf, a pullout shelf, 19 inch to 24 inch rack rail adapters, threaded adapters, adjustable position rack rails and Compaq® adapters. Each optional kit is supplied with installation hardware.

To maintain unit center of gravity as low as possible, install customer equipment from the

bottom up, starting with the heavier units. Leave available space (if any) at the top of the enclosure.

CAUTION: To avoid tipping the unit when it is 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.

The LGH can support an electrical load based on the UPS capacity. For integrated/matched models, the Environmental Control Module is normally sized to match the capacity of the UPS plus heat transmitted into the enclosure. A 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 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.

Provide enough length on customer supplied cables to allow unit to be rolled forward for rear access. Remember to connect a cable to the Little Glass House alarm contacts if required for your installation. Route customer wiring through the two horizontal cable entrance raceways. An optional internal cable management raceway (vertical) is available.

START-UP

Before applying power, make sure the computer equipment and power switches are in the OFF position. Plug the Little Glass House power cable into the customer provided receptacles/sockets. Be certain there are no obstructions (such as wires, conduit, or trash) to the front or sides of the ECM. Make sure all doors shut and seal properly. Roll the unit into final position according to the location section on page 4. If heat rejection duct option is included, be sure there are no loops or kinks in the duct.

Turn on the Environmental Control Module (ECM), or Forced Air Cooling system (FAC). Then turn on the UPS, if included. If UPS status indication is normal, turn on your computer and network equipment. The UPS will immediately supply regulated power. Battery back-up will be available after batteries are fully charged.

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 UPS module has user friendly controls and indicators. Refer to separate UPS manual for details of UPS operation and LED indicators. CAUTION: To maintain UPS battery capacity, do not store Little Glass House for more than 6 months without applying power.

Call your Liebert supplier if you have any questions or problems during the installation or operation of your Little Glass House.

OPERATION

ENVIRONMENTAL CONTROL MODULE (ECM) & UNINTERRUPTIBLE AIR SUPPLY™ (UAS)

For integrated/matched models, the Environmental Control Module is normally sized to match the capacity of the UPS module and heat transmitted into the Little Glass House™. The module is located at the bottom of the enclosure. Internal air is conditioned and circulated within the enclosure. Outside (ambient) air is used to remove heat from the 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.

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 condenser is below 80°F (27°C). The compressor in the Environmental Control Module will turn off if the internal cabinet temperature goes below 65°F (18°C).

The hot gas bypass valve is factory set so the compressor will operate nearly continuously for maximum compressor life. This valve 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).

FORCED AIR COOLING (FAC)

Forced Air Cooling can be provided by a single fan (nominally rated at 190 CFM - 323 CMH), or by dual fans (nominally rated at 360 CFM - 611 CMH). The two-speed fans are activated by a temperature switch. Ambient air is drawn through the filter at the bottom front of the unit, and discharged at the top rear.

The ON/OFF control switch is located inside the front door, on the left side. The same control box includes the temperature switch factory set at 80°F (27°C), which measures air entering the unit. If the entering air temperature goes above 80°F (27°C), the fan speed switches from low to high.

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.

For LGH models supplied with a UPS, refer to the separate UPS manual for operation and specifications.

SITENET® INTEGRATOR®

Refer to the Integrator Electrical Connection Diagram on page 21 for specifics regarding installation.

The SiteNet Integrator is a separate rackmount unit that communicates status of the UPS and LGH. The option consists of a SiteNet Integrator module that is typically mounted in the top of the LGH cabinet.

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.
