Key Telephone System 500.3 SYSTEM GROUNDING To ensure that the system will operate properly, a good earth ground is required. Use of the Telco ground (source not demark) or a metallic COLD water pipe usually provides a reliable ground path. Carefully check that the pipe does not contain insul- ated joints that could isolate the ground. In the absence of the COLD water pipe, a ground rod or other source may be used. A no. 8 AWG copper wire should be used between the ground source and the KSU and EPH2 (25 feet maximum). The farther from the ground source, the larger the ground wire used should be. The wire should be kept as short as possible and can be connected to the ground lug provided on the lower left side of the front face of the KSU (cover off) (Refer to Figure 500-l) and the right side of the EPH2. 500.4 KSU INSTALLATION Refer to Figures 500-1,500-2, and 500-3 for general mounting arrangements and dimensions. The KSU is mounted in the following manner: The KSU is designed for wall mounting only, and should not be mounted directly on a ma- sonry or dry walled surface. A wooden back- board (plywood or pressed board) of sufficient size should be attached to the wall for the KSJ to be mounted upon. The KSU mounting tem- plate should be used to identify screw hole locations. It is important that the KSU and MDF connecting blocks be mounted on the back- board. v+ FUSE 66Ml-50 BLOCKS ? n A P 1 u Figure 500-l Mounting Arrangements 500-2 Issue 1, June 1991

When the KSU is in position, the screws can be tightened and the KSU is se- curely mounted. 500.5 LIGHTNING PROTECTION The Starplus 96EX Hybrid Key Telephone System should have Central Office lines and OPX stations protected with proper lightning surge arrestors. This will provide protection from damaging surges on sensitive cabling by non-direct lightning strikes. The protection should contain a compliment of three- element gasdischarged tubes to ground high poten- tial surges, and associated circuits to absorb and filter lower level surges. This type of lightning pro- tection is available through telephone equipment supply houses. Care should be taken to ensure that such protection devices are installed in accordance with the manufacturer’s instructions and to ensure that no more than one set of protectors be installed on central office lines at the installation premises. Improper installation can be a serious safety hazard. Failure to provide the proper lightning protection will increase maintenance expense and require more available spare parts. 500.6 EXTERNAL POWER SUPPLY HOUS- ING 2 (EPH2) INSTALLATION NOTE: The second Power Supply (PS) must be added fo the External Power Supply Housing when the Expansion KSU is added. The External Power Supply Housing 2 should be wall mounted onto the same backboard as the KSU. The power supply must be located within three feet of a separately fused 15 ampere, I 17V ac power outlet. A four foot DC output cord is provided for intercon- nection of the KSU and External Power Supply. A battery backup Bypass Board is installed in the BC slot of the External Power Supply Housing 2 (EPH2). This is required to provide system power when a Battery Charging (BC) card is not installed. The power supply may be located to the left of the Basic KSU or above the BKSU. NOTE: 7he tight side of the Basic KSU should be reserved for the Expansion KSlJ. (Refer to Figures 500- 1 and 500-2) Using the template provided, spot punch the mount- ing surface through the template four corners. install four (no. 10 or larger) screws into the backboard and tighten to about l/8 inch from the mounting surface. Lift the EPH2 housing onto the four screws and tighten. Connect the DC output cord of the EPH2 to the Basic KSU by aligning the connector pins, pressing inward, then turning the collar of the connector clockwise until tight. Do not connect AC power cord to an AC outlet at this time. 500.7 POWER SUPPLY (PS) INSTALLATION Install the Power Supply(ies) into the EPH2 housing by sliding them into their respective mounting slots. Lock the power supply(ies) into the EPH2 housing by sliding the mounting lock to the left and tightening by turning clc.ckwise (Refer to Figure 500-4). Plug the associated AC IN power cord into the AC IN socket on the Power Supply(ies). Then plug the DC cord into the DC output connector on the power supply(ies). 500.8 BATTERY BACK UP INSTALLATION A Battery Charging Unit (BC) is an option that can be instafled in the External Power Supply Housing 2 and will maintain system operation during loss of AC power. A separate external 24V dc battery package must be provided. Do not make connections with the power applied to the External Power Supply Housing 2. Also remove power from the KSU by turning the power switch to off (located on the left side of the BKSU). lssuel,Junel991 500-5

External batteries may now be connected using stranded wire with crimp on ring teminals. A 24V dc (nomally two 12V dc batteries) package wifh a 40 ampere hour rating is considered maximum. lt is recommended that maintenance free gel-type bat- teries be used. The following should be considered when connecting batteries: . Batteries are to be placed in a limited access room or cabinet with adequate ventilation of any battery gases that may be present. . A battery rack or case should be used to secure the batteries and protect them. . Use the shortest length of stranded wire pcssi- ble to connect the batteries. Use wire &es recommended by the National Electrical Code ancYor local regulations. . The batteries you are installing MUST be fully charged. . The battery voltage of both 12v batteries con- nected in series MUST be 22v or greater in order for the Starpfus 96EX to function properly. If the manufacturer’s suggested float charge voltage of the batteries is different than 27.3 &3v, then the installer MUST contact VCS field Service for tie approptiate interface. lXs voltage should be br the ambient temperature expected for the equipment room. A 12 ampere, 32V minimum fuse or a 12 ampere DC instantaneous tripping circuit breaker should be in- stalled in line with the battery negative lead to protect the batteries from damage. Refer to the Typical Battery Interconnection Layout, Figure 500-6.

Keep all PCB’s in their protective anti-static bags until they are installed in the KSU. All PCB’s that are not in protective bags should be handled by the card edges only. Never lay an unprotected PCB card on a carpet& surface. Always use a grounded w&t strap when handling PCB’s. This will minimize the possibility of static damage. A. Installing the DC/DC Converter Unit (DC/DC) Locate and unpack the DC/DC Convefler Unit (DCU). Using the ejector tabs, insert the unit into the BKSU card slot 0 or DC/DC card slot. B. Installing PCBs NOTE: IMth the exception of the CPB and DC/DC, PCBs can be safely unplugged wilh thepo wer on but it is suggested that the NormalGen4ce switch be placed in the %ervicen mode while removing or in- serting into fhe system. When inserting a card into the KSU, make sure the card edges are aligned with the KSU card guides, that the service switch is in the sewice (down) posi- tion, and that the component side of the card faces to the right. Note, the card ejector tabs are cclor coded to match the designations on the KSU. Make sure the PCB’s are securely seated in their respec- tive card connectors. Press firmly on the card ejector tabs once the PCB is mounted into the KSU. The service switch should be returned to the normal (up) position. C. PCB Programming The COB (Figure 500-g), COA (Figure 500-lo), KIB (Figure 500-11) SIB and OPX cards each have a service switch on the front of the card. The switch should be in the Normal ‘(up) position for normal operation. The CPB has a DIP switch assembly for program- ming various system functions. Make sure the switches are positioned according to the functions described in Figure 500-8. The APL board provides connectors for SLU and RSM. 5og-9 Issue 1, June 1991

500.10 COPBX CONNECTIONS An FCC approved RJ2iX connector should be sup- plied by the Telco at the demarcation point. The RJ2iX should be located within 25 ft. of the KSU. All CO/PBX line connections are made on the Pl and P2 cables. The PI connector is located in the Basic KSU and the P2 connector in the Expansion KSU. A COB or COA card must be installed in the associ- ated KSU card slot in order for the CO/PBX line interface connections to be established (Refer to Tables 500-3 and 500-4). 500.1 I AMPLIFIED CENTRAL OFFICE INTER- FACE BOARD There are eight CO line circuits per card. Each card has a jumper strap (one for each of the eight CO circuits) which is set by the installer during installa- tion for either 0 db (no gain) or +3 db (gain). (Refer to Figure 500-10). GairVno gain affects multi-line conferences and trunk to trunk (DISA or off-net forward) calls. All other installation requirements are the same as for the standard COB. When Amplifted CO connections are desired it is recommended that a!! CO boards in the system be replaced with COA boards. 500.12 STATION CONNECTIONS There is a 50-pin female amphenol-type connector on each station KIB, SIB and OPX card. These allow the system to be cabled to the main distribution frame (MDF). Twenty-five pair telephone cabling must be prepared with mating connectors to extend the KSU interface circuits to the MDF. The cables are routed through the cable clamps at the bottom of the KSU to the MDF. These cables are then termi- nated on industry standard 66Ml-50 type punch- down connector blocks (Refer to Tables 500-5, 500-6, and 500-7). It is recommended that 66Mi -50 split blocks with bridging clips be used to simplify troubleshooting and to quickly isolate faults. The amphenol type connectors will be on the front edge of the printed circuits boards which are plugged into the green colored card slots. These connectors require male plug-ended cables for proper attach- ment. The actual quantity of cable required depends on the size of the system. Each time a station card is added to the system, another connector is re- quired. A maximum of six station boards can be installed in the basic KSU. After the amphenol type cable connector has been attached, the cable should be anchored to the cable clamps at the bottom of the KSU with tie wraps in order to prevent accidental disconnection. The Expansion KSU contains four station slots (Re- fer to Figure 500-3). sTARPLUS@ 96EX Key Telephone System 500.13 POWER FAILURE TRANSFER AND LBC CONNECTIONS The Power Failure Transfer Unit contajns the Loud Bell Control contacts. The package should contain: - 1PFT - 1 two-connector terminal strip - 1 amphenol clip. - 2 jack screws - 4 washer screws - I plastic terminal strip protector A. Power Failure Transfer (PFT) A maximum of two, optional Power Failure Transfer Units (PFT) can be installed in the Basic KSU. In the event of a commercial power failure, up to six CO/ PBX lines per PFT can automatically transfer to single line telephones for emergency communica- tions. These SLT’s can be either rotary or DTM F but must be equipped with CO powered ringers. These SLT stations do not have to be used for intercom, but can be if so desired. The PFT also provides the contact closure for Loud Bell Control/CO Line Control. The PFT has a 50-pin male amphenol connector that allows a 25-pair cable to be installed and terminated at the MDF. (Refer to Figure 500-12 and Table 500-6 for PFr connec- tions). B. Loud Bell Control (LBC) The Statplus 96EX System provides relay contact closure to activate optional external signaling equip- ment during incoming CO line ringing or to activate ancilliary equipment. The stations for Loud Bell Control are selected as part of system programming. Either or both of the LBC circuits may be assigned to any one station, to separate stations or to a CO Line to provide wntact closure while that CO Line is busy. The dry wntacts will follow the ringing condition of that station or will remain closed when assigned to a CO line. The LBC wntacts are installed underneath the PFT in the Basic KSU (Refer to Figure 500-3). A. Using the two jack screws, mount the tvvo-con- nectar terminal strip to the BKSU. B. Take the RD/OR wire on the back of the termi- nal strip and route through the slot where the PFT is mounted and wnnect to the RD/OR wire on the back of the PFT. C. Connect the appropriate wire (I or 2) tie wrapped to the PFT mounting hole to the Kl wnnector on the PFT. D. Insert the PFT into the hole provided (Refer to Figure 500-3) and fasten with two washer screws. Issue 1, June 1991 500-l 1
