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 3-
wire 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.
6. The location should have adequate accessibility, space and lighting for future servicing and should consider the
need for future expansion.
7. The site should be away from radio transmitting equipment, arc-welding devices, copy machines, and other
electrical equipment capable of generating electrical interference. The system should be protected from flooding
and heavy machinery as well as excessive dust and vibration.
