2.302 (continued)
Connect Type N coaxial jumper cable from the RF module to waveguide
and run the waveguide, in turn, to the antenna. Refer to Figure 2-5.
Allow approximately 3 inches of hole clearance through wells for the
cable connector. Connect the waveguide to ground. Ensure that the
outdoor connection from RF module to antenna is properly
weetherproofed with 3M Scotch" 130C or equivalent.
With reference to subsection 2.5. power up the radio system.
0 When a maintenance terminal is used, connect it to the LOCAL port on
the controller and set its data parameters (9600 baud, N-B-l) per
subsection 2.6. Also set the transmitter power level.
Align the near-end and far-end antennas following the instructions in
Section 3, paragraph 3.03.
Test the performance of the radio system from the maintenance
terminal as described in Section 4.
Turn up the radio system (put the Model 9000 into service)
2.4 Connecting Model 9000 to Facility
2.401 Mount the 9000 assembly in the rack, making sure of the 24-inch minimum
space clearances (refer to Figure 2-1). then perform the steps in the
following paragraphs to connect it to the facility.
@ NOTE: ‘
The method of distributing powar to the Model 9000 equipment within
the rack is entirely the customer's option. It can be connected Sthrough
a rack fuse and alarm panel by way of bus bars or with aepaifif’e power
cables distributed from a primary power connection point on the rack.
Actual power connections to the 9000 are bv way of terminal block TB1
on the Control Module‘s back panel.

Power
Plant battery connects to the Model 9000 equipment at terminal block TB1
on the controller's rear panel. The assignments for this terminal block
include FRM GND, BAT GND, and —24/-48 Vdc. Refer to Figure 2-6.
Follow the steps below to make power and ground connections to the
shelf.
{Eb Use a DC power source capable of supplying two (2) amps
minimum with a ripple noise of less than 100 MVrma.
1 Connect the plant Battery A and Battery B power feeds to TBl
terminals —24I—48 Vdc A and —24l~48 Vdc B, respectively. (Remove
shorting clips that are not required.)
2. Connect the plant battery return to TBl terminals BAT GND A and BAT
GND B. respectively. (Remove shorting clips that are not required.)
3. Connect the rack frame ground to TB1 terminal FRM GND. (Remove
shorting clips if appropriate.)
4. Dress the power and ground lines across the back of the shall, then
down or up the edge of the rack frame (as required by your site's cable
rune).
Alarms
The minor and major alarms (rem Model 9000 to facility alarm equipment
connect through TBZ on the controller‘s rear panel.
“
® NOTE:
The alarm Form A relay contacts can handle a maximum of 0.1 amp at
100 Vdc. (Form A is normally open.)

Lightning Protection
All grounds for lightning are left outside the Central Office structure while
equipment grounds are entirely inside the structure. The only place where
everything ties together is at the master ground bar. typically located in a
cable vault or basement or near the battery room. Lightning, or anything
possibly conducting lightning, is kept outside and carried to a well-certified
ground point (typically <1 chm with respect to absolute ground). Exactly
what is implemented as a grounding scheme depends on adherence to the
National Electrical Code, local regulations. and company practices. These
are weighed against the types and value of transmission equipment
installed as well as the traffic revenue loss in the event of disruption.
The Model 9000 has internal circuits designed to protect the £11051
interfaces and its own connections from the effects of lightning. However,
to ensure the unit is protected, the 9000 must be properly connected to
earth ground as shown in Figure 2-7. Outdoor lightning protection, which
is entirely the customer's responsibility, requires cutting into the interface
cable and adding the appropriate lightning protectors (refer to Figure 2-8).
A CAUTION:
Refer the installation of additional lightning protection to a qualified
service engineer.

Model 9000 Power-up
2.501 The Model 9000 has no power control of its own. All power to the radio
is by way of the circuit breakers or fuses that feed to the -24/-48 Vdc
connection at the controller unit. To apply power to the radio, simply
switch on the facility battery 'A' and 'B' branch circuit breakers or fuses.
2.6 Connecting Maintenance Terminal
2.601 The Model 9000 has two ElA RS-2320 connections that can be used for
controlling the radio locally and remotely through a modem. The terminal
(or Local) input on the front panel of the controller must use a VT-100 or
compatible device (e.g. a PC running a VT-100 terminal emulator), The
modem (or Remote) input is located on the rear of the controller unit. The
data rate and format for the virtual data circuit ports default to 9600 bps.
8 data bits, no parity bit, and one stop bit,
