SECTION 3. INSTALLAT ION

3.1 INTRODUCTION

As with any sophisticated communications device, installation of the GDK-20W System requires the care and

fore-thought of a competent technician. Installation proceeds in 4 major steps:

-. Site Preparation

-. KSU Installation

-. PCB Installation

-. System Wiring

-. DECT Installation

3.2 SITE PREPARATION

General Site Considerations

The first step is to locate an acceptable site for the common equipment.(KSU, boards, etc.) When locating a mounting site for the KSUs, the following points must be considered:

1. The KSUs are designed for wall mounting and should not be mounted directly to a masonry or plaster board wall. It

is recommended that a ½ inch thickness plywood back-board be firmly mounted to the wall first and then the KSU.

2. The location must have access to 220~240 Volt AC, 50 - 60 Hz with a circuit breaker or fuse rated at 15 amps. A 3wire parallel blade grounded outlet should be within approximately 2 meters (6 feet).

3. The location must have access to a good earth ground, such as a metallic cold water pipe with no non-metallic joints. The ground source should be located as close as possible to the system.

4. The system should be located in an area which is well ventilated with a recommended temperature of 20 - 26 degrees C (68 - 78.8 degrees F) and a relative humidity of 5 - 85 % (non-condensing).

5. The system should be located within 8 meters (25 feet) of the telephone company's termination point. Also, the location should be within the prescribed station loop lengths for all keysets and terminals. If existing cabling is to be employed, the location of existing cabling and conduits should be considered.

KSU Grounding

The GDK-20W mains lead must be connected to a building mains supply that includes an earth connection in conformance with current IEE requirements.

Earthling is required for user safety and to minimize EMC interference.

If does not connected mains earth, to ensure proper system operation and for safety purpose, a good earth ground is required. A metallic COLD water pipe usually provides a reliable ground. Carefully check that the pipe does not contain insulated joints that could isolate the ground path. If insulated joints exist, another earth ground source must be used or, if allowed, the joints may be bridged.

A #14 AWG or larger copper wire should be used between the ground source and the connector, CN27, of the KSU. The wire should be kept as short as possible, it is recommended that the wire be no longer than 8 meters.(about 25 feet)

3.4 PCB INSTALLATION

PCB Handling & General Installation

All boards should not be installed or removed while power applied.

Power must be turned off prior to insertion or removal of the PCB. The system PCBs contain digital circuitry which can be damaged by exposure to excessive static electricity. When handling PCBs, a grounded wrist strap should be used to protect the boards from static discharges. Also, use common sense when handling the PCBs. For example, do not place a PCB in locations where heavy objects might fall on the PCB and damage components.

To insert a PCB, hold the PCB and, with component side facing right, insert the card into the MBU’s din connector firmly and tighten. To remove a PCB, reverse the procedure. Installation method of PCB is shown in Figure 3.4.1.
