Installation Manual • • • KSU Installation Page 23 A6-506000-642-01 Xen AlphaRelease 1.0 SECTION 1 GENERAL INFORMATION This section provides the requirements for installing the system. The installer should be familiar with this section before installing the system. SECTION 2 SITE PREPARATION The technician should plan the installation before actual work begins. Advanced planning will minimize time, cost and disruption of the customer’s business activities. Additional benefits include flexibility for changes and expansion, efficient maintenance and increased customer satisfaction. Precautionary Information The following warnings shall be observed during installation: 1. Never install telephone wiring during a lightning storm. 2. Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations 3. Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface. 4. Use caution when installing or modifying telephone lines. Site Survey Inmost cases, a survey of the customer’s premises is needed to develop cost estimates of the installation. Preliminary information is used to determine the placement of the Main Distribution Frame (MDF). A second visit to the site may be necessary to obtain the exact dimensions of the area selected for MDF, cable lengths and possible IDF (intermediate Distribution Frame) locations. Site Limitations Installation of a telephone system is seldom a routine procedure. The uniqueness of each customer’s situation requires a tailored approach to each job. In selecting a permanent site for the MDF, the technician may encounter problems such as, but not limited to the following: !Limited space is available and must be used regardless of its suitability. !The available space may be adequate, but may pose one or more environmental hazards. !The proposed location has limitations. Such as insufficient lighting or the lack of a suitable ground for grounding the KSUs. Whatever the nature of the adversities encountered, the technician must make the necessary decisions to arrive at the best possible solution for installing the equipment. It is beyond the scope of this document to cover all possible situations, precautions and actions. CHAPTER 2KSU Installation

Page 24KSU Installation • • • Installation Manual A6-506000-642-01 Site Selection Conditions KSU Installation Site The following conditions should be met at the site selected for the KSU. !The KSUs should be wall mounted to protect against accident or flooding. !The KSU should not be located directly beneath pipes, due to the possibility of leaks or condensation causing damage to the equipment. !The area where the KSU is to be located must be free of corrosive and inflammable gases, excessive chemical or industrial dusts and other materials that could cause a hazard to personal or to the proper functioning of the equipment. !Operating ambient temperature and humidity must be within the limits specified in Section 2.6 – Environmental Conditions in this chapter. !The operation of the system is virtually noiseless and allows a wide selection of installation sites. Care should be taken to ensure the KSUs do not present a hazard to office traffic. For purposes of economy, a central location to minimise cabling is often used. !The basic KSU weighs approximately 4 Kg. Select a strong wall for mounting purposes. !Place the KSU according tot he following spacing specifications • Space distance between the KSU and the ceiling: 50 cm or more • Space distance on both sides of the KSU: 30 cm or more • Space distance on front of KSU: 50 cm or more !Avoid connection of the KSU to an AC receptacle used in common with any other device (computer, facsimile machine, copier, etc.) !Ensure that any AC Outlet to be connected is properly grounded. !Avoid connection of KSU near radio receivers or electrical noise generators (e.g. welding equipment, machinery). CAUTION 1. The socket outlet shall be installed near the equipment and shall be easily accessible. 2. Plug the system into the mains supply (240 V ac) before terminating a telecommunications network conductor to the system. 3. Danger of explosion if batteries are incorrectly replaced. Replace only with the same or equivalent type recommended by the manufacturer. Dispose of used batteries according to the manufacturers instructions Multiline Telephone Installation Site The following conditions should be met at the site selected for MLTs. !Ensure the cable length and line resistance (loop), between the KSU and the telephones comply with the specifications shown in Table 1-1: Multiline Telephone Loop Resistance and Cable Length Multiline Telephone Loop Resistance and Cable Length. !Some devices require an external power supply. Select a place where they can be easily connected to an AC outlet. !Telephones intended for handsfree use should be kept away from areas subject to loud noise or echoing.

The Key Service Unit The B614-B13 KSU is the system cabinet that houses a power supply, battery backup and fixed slots for installing option/expansion cards. The KSU is wall mounted.

Below is a diagram showing how to remove the cover of the KSU. 1. Remove the cover by loosening the two bottom screws with a philips head screwdriver (the screws remain in the cover to keep from misplacing them). Pull the cover away from the KSU and lift upward. 2. To replace the cover, locate the tabs on the top of the cover into the slots in the top of the base and then push the bottom of the cover inwards. Tighten the two cover screws.
