SECTION I INSTALLATION

INTRODUCTION

AeroComm strongly recommends that the user install the two rack enclosures for the system by bolting them down onto level concrete flooring. The user must equip the concrete floor with appropriate anchors and drill the floor of the cabinet to match. AeroComm recommends stainless steel wedge anchors with a minimum diameter of 3/8” and a thread length of 2 ¼”. The hole pattern in the concrete floor and in the floor of the cabinet should be arranged such that the anchor studs are centered 2” from each wall of the cabinet in each of the four corners.

WARNING

FAILURE TO SECURE THE CABINET AS RECOMMENDED MAY RESULT IN

CABINET TIP-OVER DURING INSTALLATION OF THE POWER SUPPLIES.

AeroComm recommends installing the two cabinets 3 feet apart. This separation distance provides easy access to the sides and top of each cabinet; additionally, this separation provides necessary RF isolation of the two units. Under no circumstances should the two units be located more than 10 feet from one another; separation distances greater than 10 feet will increase path loss on the RF cables connecting the two units and result in nonoptimal operation.

DETAILED INSTALLATION INSTRUCTIONS

MECHANICAL INSTALLATION OF THE CABINETS

Determine the bolt pattern to be used for anchoring the two cabinets. Install anchors in concrete floor & match drill cabinet floors. Position cabinets over the floor anchors and fasten the cabinets to the floor.

WARNING

ENSURE AC POWER SERVICE LINES ARE NOT LIVE PRIOR TO

CONNECTING TO THE EQUIPMENT CABINETS.

RESTRICTION ON THE TITLE PAGE OF THIS MANUAL

AC POWER CONNECTION

Install AC power conduit. Each cabinet is configured with clamping-ring hardware suitable for attachment of ½” electrical conduit. Each cabinet is fitted with an electrical junction box inside at the top rear of the cabinet. Remove the cover plate and connect the AC source lines to the appropriate terminals in the junction box. Refer to figure 1. Re-install the cover plate.

SETTING THE THERMOSTATS

Set the thermostat inside each cabinet for 90-95ºF (32-35°C). This will keep the cabinet at optimal operating temperatures. Refer again to Figure 1. The Thermostat is marked with three dots between 80ºF and 130ºF(27-54°C). Turn the thermostat dial so the pointer is just past the first dot above 80ºF (27°C).

NOTE

THE THERMOSTATS MAY BE ADJUSTED AFTER INSTALLATION BY

REMOVING THE GRILL AND FILTER ON THE TOP OF EACH CABINET. THE USER CAN THEN REACH THROUGH THE ACCESS HOLE TO ADJUST THE THERMOSTAT SETTINGS.

CONNECT EXTERNAL RF CABLING

Connect the two cabinets to one another using low-loss ½” heli-axial cable as shown in the Figure 2 above. Connect the cable leading to the roof antenna to the type N connector on the top right (when viewed from the front) of the “Talk In” / High Band cabinet. Connect the radiating cable to the type N connector on the top right (when viewed from the front) of the “Talk Out” / Low Band cabinet.

INSTALLING POWER SUPPLIES & BATTERY CHARGER

The power supplies and battery charger are the first items to be loaded into the equipment cabinets by the user. The following items were shipped in each cabinet (listed from top to bottom of the cabinet):

I. Duplexer II. Power Control Breaker Panel III. LNA / 8-Way Splitter IV. VME Chassis for Channel Cards V. Blower

1. Verify equipment listed above is installed in each cabinet. Refer to Figure 3 below.

POUNDS.

THE SINGLE POWER SUPPLY MODULE WEIGHS ABOUT 40 POUNDS.

THE BATTERY CHARGER MODULE WEIGHS ABOUT 15 POUNDS.

TWO PEOPLE SHOULD LIFT THE MODULES TOGETHER TO

PREVENT INJURY DURING INSTALLATION INTO THE CABINETS.

USE OR DISCLOSURE OF DATA CONTAINED ON THIS PAGE IS SUBJECT TO THE

2. Locate the dual power supply modules (2 ea.), the single power supply module (1 ea.)

and the battery charger module (1 ea.).

The modules are distinguished by the following features:

• The dual power supply modules have two large gold power supplies (made by

Acopian) mounted side-by-side in the chassis.

• The single power supply module has a single gold Acopian power supply mounted on

the left side of the chassis (when viewed from the front).

• The battery charger module has a single yellow TrueCharge 40™ battery charger

(made by StatPower) mounted on the right side of the chassis (when viewed from the front). The battery charger module is shown in Figure 4.

Figure 4. Battery Charger ModuleFigure 4. Battery Charger Module

CAUTION

MAKE SURE THE POWER SUPPLIES AND CHARGER ARE SWITCHED OFF

PRIOR TO INSTALLATION. THESE UNITS ARE OFF WHEN THE CIRCUIT BREAKER PUSS-PULL SWITCHES ON THE FRONT PANEL ARE PULLED OUT (THE WHITE BAND AROUND THE BODY OF THE SWITCH IS VISIBLE).

3. Load one dual power supply module into the High Band equipment cabinet. This

module goes directly above the LNA / 8-Way Splitter Module.

50289-BDA

USE OR DISCLOSURE OF DATA CONTAINED ON THIS PAGE IS SUBJECT TO THE

RESTRICTION ON THE TITLE PAGE OF THIS MANUAL

4. Attach the power connections on the rear of the chassis. Refer to Figure 5 below.

Note that there are two connections that must be made on the left side of the module (as viewed from the front). The longer harness lead in the cabinet should be attached to the connector further in from the left edge of the cabinet.

5. Load the other dual power supply into the Low Band equipment cabinet, directly

above the LNA / 8-Way Splitter Module.

6. Attach the power connections on the rear of the chassis as in step 4.

7. Load the single power supply into the High Band equipment cabinet, directly above

the dual power supply module.

8. Attach the power connections on the rear of the chassis. Note that the single power

supply has only one connection that must be made on the left side of the module (as viewed from the front).

9. Load the battery charger supply into the Low Band equipment cabinet, directly above

the dual power supply module.

10. Attach the AC power connection on the right rear of the chassis.

11. Connect unterminated AC power leads to the rear of the charger using the wire nuts

provided. Install the cover over the wire nut junctions per the manufacturer’s instructions provided in the appendix.

INSTALLING THE IF CHANNEL MODULES

The channel slots have been factory preset to be installed in order, from low to high frequency, from left to right, in the VME-style IF Channel rack located in lower middle of each cabinet.

Note that each IF channel module is labeled with the frequency to which it was factorytuned; the frequency is written on the “TESTED” sticker located on the top rear corner of the RF enclosure in each module.

Also note the bank of jumpers at the rear of each IF channel module; the jumper position determines the keying of the power amp directly below the IF channel rack and, consequently, which slot each IF channel module should be placed in. The IF channel module slots are ordered 1 through 8 from left to right.

The factory preset frequencies and jumper settings for the High- and Low-Band IF Channel Modules are listed in Table 1. Jumper location is depicted in Figure 7
