Installation

Overview

This section explains how to install the ZR310 community Repeater Panel into the GR300 and complete the cable connections that were started in the Installation section of the GE300 Maintenance Manual. If you require access to the indicators, jumpers, or other components, refer to the Maintenance section for disassembly procedures.

Equipment Required For Installation

The following equipment is required for installation:

•a communications service monitor and ONE of the following

•a hand-held or mobile radio with DTMF encode capability

•a DTMF telephone

•a PC capable of running the Motorola radio service software (RSS)

•an ANSI terminal communications program

Installation Procedures

If you have followed the installation procedures found in the Installation section of the GR300 main manual, the GR300 is assembled. Now you need only to install the ZR310, finish the required cable connections, reinstall the fan assembly, and perform the required tests and adjustments. To identify the parts and their corresponding call outs, refer to Figure.

Assembly

Perform the following steps to install the ZR310 into the GR300 housing and to complete cable connections. The RF and repeater cables should already be connected to the radios, if you installed them according to the Installation section of the GR300 Maintenance Manual.

Install the ZR310 Into the GM300

1.STOP! Before going any further, did you make sure that the jumpers inside the GM300 transmit and receive radios were set to the correct positions? (Refer to table 2-2.)

2.Place the ZR310 on the top shelf of the GR300 repeater housing, allowing the rear panel to be partially exposed.

3.Connect the receive radio repeater connector to the ZR310 Receive connector (Figure 2-1).

4.Connect the transmit radio repeater cable to the ZR310 Transmit connector.

5.Position the ZR310 so that its mounting screw holes are aligned with the corresponding mounting holes on the repeater housing

6.Using a T25 Trox screwdriver, secure the ZR310 to the repeater housing using two M5x0.8x8 machine screws (7).

7.One end of the equipment power cable has only one connector. Connect it to the top connector on the power supply (Figure 2-2).

8.The other end of the equipment power cable has two connectors. Connect one of these connectors to the receive radio and the other to the transmit radio.

9.Connect the lower frequency radio to the LOW port on the rear of the duplexer. (Figure 2-3).

10.Connect the higher frequency radio to the HIGH port on the rear of the duplexer. (Figure 2-3).

11.Thread the grounding nut onto the grounding lug.

CAUTION

To avoid damage to cable tabs and radio components,

install cables with locking tabs up
