Battery Maintenance Guidelines

The battery maintenance instructions listed below are for reference only. Battery manufacturer’s instructions for
transportation, installation, storage or maintenance take precedence over these instructions.

• To prevent damage, inspect batteries every 3 months for:

Signs of battery cracking, leaking or swelling. The battery should be replaced immediately by authorized personnel

using a battery of the identical type and rating.

Signs of battery cable damage. Battery cable should be replaced immediately by Authorized Personnel using

replacement parts specied by vendor.

Loose battery connection hardware. Refer to battery manufacturer’s documentation for the correct torque and

connection hardware for the application.

• Apply battery manufacturer’s specied antioxidant compound on all exposed connections.

• Verify battery terminals and/or exposed connection hardware is not within 2 inches of a conductive surface. Reposition

batteries as necessary to maintain adequate clearance.

• Clean up any electrolyte (battery emission) in accordance with all federal, state, and local regulations or codes.

• Proper venting of the enclosure is recommended. Follow the Battery Manufacturer’s approved transportation and

storage instructions.

• Always replace batteries with those of an identical type and rating. Never install old or untested batteries.

• Do not charge batteries in a sealed container. Each individual battery should have at least 0.5 inches of space

between it and all surrounding surfaces to allow for convection cooling.

• All battery compartments must have adequate ventilation to prevent an accumulation of potentially dangerous gas.

Recycling and Disposal Instructions

Spent or damaged batteries are considered environmentally unsafe. Always recycle used batteries or dispose of the
batteries in accordance with all federal, state and local regulations.

Electrical Safety

• Lethal voltages are present within the power supply and electrical boxes. Never assume that an electrical connection

or conductor is not energized. Check the circuit with a volt meter with respect to the grounded portion of the enclosure
(both AC and DC) prior to any installation or removal procedure.

• Always use the buddy system when working under hazardous conditions.

• A licensed electrician is required to install permanently wired equipment.

• Input voltages can range up to 240Vac. Ensure that utility power is disabled before beginning installation or removal.

• Ensure no liquids or wet clothes contact internal components.

• Hazardous electrically live parts inside this unit are energized from batteries even when the AC input power is

disconnected.

Mechanical Safety

• Keep hands and tools clear of fans. Fans are thermostatically controlled and will turn on automatically.

• Power supplies can reach extreme temperatures under load.

• Use caution around sheet metal components and sharp edges.

Battery Safety Notes

WARNING!

Lead-acid batteries contain dangerous voltages, currents and corrosive material. Battery
installation, maintenance, service and replacement must be performed only by authorized
personnel.

Chemical Hazards

Any gelled or liquid emissions from a valve-regulated lead-acid (VRLA) battery contain dilute sulfuric acid, which is harmful
to the skin and eyes. Emissions are electrolytic, and are electrically conductive and corrosive.

To avoid injury:

• Servicing and connection of batteries shall be performed by, or under the direct supervision of, personnel

knowledgeable of batteries and the required safety precautions.

• Always wear eye protection, rubber gloves, and a protective vest when working near batteries. Remove all metallic

objects from hands and neck.

• Batteries produce explosive gases. Keep all open ames and sparks away from batteries.

• Use tools with insulated handles, do not rest any tools on top of batteries.

• Batteries contain or emit chemicals known to the State of California to cause cancer and birth defects or other

reproductive harm. Battery post terminals and related accessories contain lead and lead compounds. Wash hands
after handling (California Proposition 65).

• Wear protective clothing (insulated gloves, eye protection, etc.) whenever installing, maintaining, servicing, or

replacing batteries.

• If any battery emission contacts the skin, wash immediately and thoroughly with water. Follow your company’s

approved chemical exposure procedures.

• Neutralize any spilled battery emission with the special solution contained in an approved spill kit or with a solution

of one pound Bicarbonate of soda to one gallon of water. Report chemical spill using your company’s spill reporting
structure and seek medical attention if necessary.

• All battery compartments must have adequate ventilation to prevent an accumulation of potentially dangerous gas.

• Prior to handling the batteries, touch a grounded metal object to dissipate any static charge that may have developed

on your body.

• Never use uninsulated tools or other conductive materials when installing, maintaining, servicing or replacing batteries.

• Use special caution when connecting or adjusting battery cabling. An improperly connected battery cable or an
unconnected battery cable can make contact with an unintended surface that can result in arcing, re, or possible

explosion.

For ground mount congurations, do NOT exceed a maximum height of 72" (1.8m).

2.2 Site Selection

• Where possible, select a site above the 100-year ood plain and away from houses.

• Place in a shaded location to minimize the effects of solar loading.

• Locate in an area where airow can be maximized.

• Avoid locating the enclosure where it is an obstruction and would inhibit visibility.

• Locate the enclosure away from sprinkler systems or other sources of forced water.

• Locate the enclosure out of the prevailing wind to minimize the buildup of snow or the

accumulation of wind-borne dust.

• Ensure soil conditions are suitable for the the appropriate grounding system installation.

• Ensure cabling has been run and terminated at the site.

• Decide whether the enclosure will be placed on a precast concrete pad or on a pad poured on site.

• Contact a cable locating service, the local utility, and adjacent building supervisors to ensure

installation location and cable routing does not interfere with existing utility connections.

ATTENTION:

Ensure that all enclosure installations are installed per local, state, and federal codes and regulations. Local,
state, and federal codes and regulations supersede information provided in this manual.

3.3 FBE2322 AC Air Conditioner

Theory of Operation:

The FBE2322 Enclosure AC Air Conditioner is an ICEQube1000V/ICEQube2400VXS. The air conditioner
is powered by a 120Vac 15A receptacle inside the enclosure. The ICEQube1000V draws 3.1A, and the
ICEQube2400VXS draws 7.1A.

The controller is located on the inside of the door and the digital display shows internal temp. The external
condenser fan turns on with the compressor when unit calls for cooling. There is a factory default off cycle
time delay of 3 ½ minutes on the compressor and condenser fan.

For more information see ICEQube Operation and Installation Manual. The air conditioner will maintain
enclosure temperature in cooling mode at the 25°C set point as long as cooling capacity is not exceeded.
In heating mode, the unit will maintain 10°C using a heating element mounted in the internal fan return air
stream. See Table 3-1 for Factory Default settings and Fig. 3-1 for control panel description.

NOTE:

The internal evaporator fan runs continuously.

3.4 FBE2322 Heat Exchanger

General Operation:

The heat exchanger moves the heated cabinet air into a network of closed loop vents that are in close
contact with closed loop vents with ambient air passing through them. This process transfers heat out of
the cabinet maintaining a constant internal temperature.

Features:

• Programmable variable speed DC fan controller with self-test.

• Internal fan: Off below 5ºC. On at 10ºC min speed; Variable to max speed between 20ºC to 35ºC.

• External Fan: Off below 15ºC. On at 20C min speed; Variable to max speed between 30ºC to 45ºC.

• High Temp alarm: 70ºC.

• Low Temp Alarm: -50ºC.

• Fan fail: Alarm contact loop open on alarm.

3.5 FBE2322 Emergency Fan

General Operation

When the primary cooling system cannot maintain adequate enclosure temperature, the emergency fan
thermostat closes energizing the emergency fan relay. This activates the form C dry contact alarm. The
high temperature alarm activates, the emergency air dampers open and the emergency fans turn on. Fan
air pressure pushes open the discharge air check valves and an electronic solenoid opens the air intake
damper.

Features:

• Two 118 CFM fans are powered by a variable speed temperature control. Fans turn off below
25ºC. Fans turn on at 25ºC and increase from 50% to 100% full speed with increased enclosure
temperature from 25ºC to 45ºC.

• Dual Fan Control PCBA has a green LED to indicate proper function, a red LED to indicate an alarm
condition and a push button test feature. During the test fans momentarily ramp up to full speed and
the alarm condition will be indicated. After this test sequence the fans will return to normal speed and
the alarm will clear with green LED indicated. Emergency fan solenoid does not have low voltage
disconnect (LVD) protection.

• One form C dry contact alarm, open on alarm.

Emergency Fan System Power Requirement:

• 24 or 48VDC input power.

• 3A fuse or circuit breaker is required (not provided unless congured with Cordex shelf or GMT fuse

panel options).

• 20awg input power leads provided (see wire labels for correct voltage and polarity).

• Maximum power draw 36W.

4.0 Maintenance

4.1 FBE2322 Enclosure Maintenance

Monthly, visually inspect the enclosure for any mechanical damage that may allow insect or rodent
ingress into the enclosure. Ensure fasteners and hinges are tightened and in a state of good repair
(free from rust, damage, etc.). Inspect insect screens for damage and replace if necessary. Clear away
any windblown dust or insect debris from inside the cabinets. Inspect and maintain batteries per the
manufacturer's recommendations.

Annually ensure that all electrical components are operable and in good repair. Repair or replace any
component that shows excessive sign of wear or breakdown per the manufacturer's recommendations.

4.2 FBE2322 Environmental Control Maintenance

4.2.1 FBE2322 Air Filter Replacement

For fan cooled applications, the system has directional lters that should be inspected for

cleaning or replacement every six months depending on time of year or environment. Clean the

lters by back ushing with water in the direction indicated on the lter and reinstall the lter.

Filter placement is directional.

4.2.2 FBE2322 Heat Exchanger

The lterless design of the Heat Exchanger provides long-term low maintenance operation.

Occasional cleaning of the vent openings may be necessary to clear insects or windblown debris.
If further maintenance is required please Contact Alpha Technical Support.

4.2.3 FBE2322 AC Air Conditioner

Ambient Air Filter: It is recommended that the ambient air lter be inspected and cleaned

regularly, at least every 3 to 6 months, or more frequently depending upon ambient conditions.
Refer to the ICEQube Maintenance Manual for detailed information about maintaining the
Ambient Air Filter.

Condensate Management System: The condensate management system should be checked
periodically for scale, sludge and debris that may cause the drip outlet to clog. Maintenance
of the condensate management system will require removal of electrical power from the Ice
Qube system. Unplug the AC power cord from the 120Vac 15A receptacle within the enclosure
and ensure that the ICEQube system is disconnected from power. Follow all instructions in the
ICEQube Manual for cleaning the Condensate Management System before reconnecting the air
conditioner to the power receptacle.

Alpha mounts the Air Conditioner Filter bracket for security. Using pin-in-hex screws and orienting

the lter bracket opening toward the enclosure door prevents unauthorized removal of the lter.
See page 36 for instructions on changing the lter and/or reorient the bracket for convenience.
