1.0 Introduction, continued 1.
2.0 Installation 2.1 FBE2322 Enclosure Installation Overview Installation requirements may differ for each configuration or customer specific application. The following instructions provide guidelines for the most common enclosure configuration installations. Always follow local codes and ordinances when designing and implementing your backhaul enclosure plans. Table 2-1 provides installation options for standard configurations.
2.0 Installation, continued 2.3 WARNING! Follow all rules and guidelines for safe lifting operation. A Secure the lifting straps/cable to the lifting ears. The length of the cable/strap between the lifting ears and the hook (A) is at least twice the distance (B) between the lifting ears (see Fig. 2-1). B NOTE: Remove the lifting ears after installation. The ears are made of steel and may rust over time. Fig. 2-1, Enclosure Lifting Arrangement 2.
2.0 Installation, continued 2.4 Enclosure Installation, H-Frame Mounting continued Most codes require the base of the enclosure to be located a minimum height from the ground. Always verify mounting height requirements before proceeding.
2.0 Installation, continued 2.5 Enclosure Installation, Pole Mounting CAUTION! • • • Never transport the unit with installed batteries. Doing so can cause injury or damage to the enclosure and installed equipment. Install the batteries after you transport the unit to the site and secure it to the pole. Alpha recommends that you position the enclosure on the opposite side of the pole from traffic. This reduces the danger of falling equipment in the event that a pole is struck by an automobile.
2.0 Installation, continued 2.5 Enclosure Installation, Pole Mounting, continued 2.5.1 Wooden Pole, continued 5. Secure the brackets to the pole using the 5/8" (16mm) machine bolts, washers, and nuts. 6. Lift the enclosure onto the brackets. It might be necessary to rock and pull the enclosure to properly seat it on the brackets. 7. Secure the enclosure to the brackets using the 3/8"x 3/4" hex bolts. 8. Make sure all nuts and bolts are fully tightened and the flanges of the brackets seat in the wood. 9.
2.0 Installation, continued 2.5 Enclosure Installation, Pole Mounting, continued 2.5.2 Concrete or Steel Pole Tools and Materials Required (customer supplied): • Stainless steel banding (or equivalent), rated to support loaded enclosure and sized for pole diameter • Assorted sockets Procedure: 1. Unpack the enclosure and galvanized brackets; turn the enclosure facedown on a soft surface. 2. Slide a bracket up through the enclosure’s lower mounting bracket.
2.0 Installation, continued 2.6 Ground-mount Installation CAUTION! Never transport the unit with installed batteries. Doing so can cause injury to the installer or damage the enclosure and equipment. Install the batteries after you transport the unit to the site and secure it to the pad. ATTENTION: It is the responsibility of the installer to meet the requirements of all applicable national and local codes.
2.0 Installation, continued 2.6 Ground-mount Installation, continued Typically, Alpha Technologies recommends using precast polymer mounting pads. The size of the mounting pad is determined by the size of the enclosure. Precast pads provide proper enclosure support and easy installation. They also provide knockouts for coax and service sweep openings and pre-installed threaded inserts for enclosure attachments. 38.53" 14.76" 3.937" ø0.375" 0.0" ø5.26" ø0.375" ø9.62" 13.03" ø13.762" 3.937" 10.48" 36.

2.0 Installation, continued 2.6 Ground-mount Installation, continued Before installation verify the following: • All necessary grounding rods and materials are in place. • Utility power is on site in accordance with the NEC (National Electric Code). • Review and comply with all local safety practices for working with high-voltage systems. • All necessary permits and permissions are granted. • The lifting/transport path is free of obstructions.
2.0 Installation, continued 2.7 Enclosure Grounding NOTE: Alpha Technologies recommends using the grounding method illustrated below. The grounding method for a particular site is dependant upon soil type, available space, local codes, NEC (National Electric Code), and other site-specific characteristics. ATTENTION: It is the responsibility of the installer to meet the requirements of all applicable national and local codes.
2.0 Installation, continued 2.8 Equipment Installation, FBE2322-ENC The FBE2322 Enclosure system's modular design and flexibility allow for a wide variety equipment installation options. A standard configuration example is shown below. Consult an Alpha Applications Engineer for more details about approved configurations.

2.0 Installation, continued 2.9 Equipment Installation, FBE2322-ENCBEE The FBE2322 Enclosure system capabilities may be expanded by adding additional enclosure sub-units. A standard configuration example for that scenario is shown below. A standard configuration example is shown below. Consult an Alpha Applications Engineer for more details about approved configurations.
2.0 Installation, continued 2.10 Battery Installation WARNING! Electrical shock can injure or kill. Remove any metallic personal items (rings, watches, etc.) before working with batteries. Always use insulated tools. Only qualified personnel should install batteries. The FBE2322 Enclosure system allows for battery storage in the FBE2322-ENC.

3.0 Environmental Control Systems 3.1 FBE2322 Enclosure Environmental Control Overview The FBE2322 Enclosure system has four integrated environmental control systems and an alternative emergency backup system. The following options are available: • Convection Cooling • Fan & Filter Cooling • AC Air Conditioning • Heat Exchanger • Emergency Fan (Optional for Air Conditioning/Heat Exchanger units) The following sections provide further information for each environmental control option.
3.0 Environmental Control Systems, continued 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.
3.0 Environmental Control Systems, continued 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: 3.5 • Programmable variable speed DC fan controller with self-test. • Internal fan: Off below 5ºC.
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.
