On-Wall Mounting Using a Wall-Mount box Attach the AN-8031 MS to the YC-251 Wall-Mount Box installed on a wall. Wall Accessory screws The AN-8031 MS comes with 2 types of screws: oval head combination screw M4 x 25 and oval head slotted screw UNC No.6 x 18. For the electrical box provided with unified threads, use the oval head slotted screws UNC No.6 x 18. [Installation completion drawing] 3. WIRING 3.2. Connection to RS-191 3.1. Connection to the Exchange AN-8000EX Exchange 16 lines To connect the cables from the AN-8000EX Exchange to the AN-8031 MS, use the removable terminal plug (2P) supplied with the AN-8031 MS. The cables have no polarity. Connecting the RS-191 Option Handset to the AN-8031 MS permits handset conversation. Step 1. Remove the handset jumper attached to the AN-8031MS's handset connection terminal, then insert it to the socket on the RS-191's rear PC board. RS-191 rear Note Though the socket on the PC board is faced inside, you can insert the handset jumper into the socket from the side. Step 2. Install the ferrite clamp (supplied with the AN-8031 MS) onto the RS-191's handset cables. Then, connect the cables to the AN-8031 MS's handset connection terminal. Ferrite ciamp (accessory) AN-8031 MS 3.3. Connection to External Switch 3.4. The Type of Cables External switches such as footswitches can be connected to the AN-8031 MS's external dial input terminals, Terning on each switch connected to the terminal [7], [8], [9], or [C] permits the same operation as performed by pressing the dial [7], [8], [9], or [C], Note The cable length from the external switch should not exceed 3 m. [Connections] The types of cables are to be determined according to the following conditions. • Twisted pair wires (such as those used for electronic push-button telephone) are to be used for wiring between the Exchange and the stations in principle. » The number of cables pairs laid should be determined considering the possibility of future expansion of the system. • Outdoor wires should be used where wiring passes through inaccessible areas such as ceilings or under floors where the maintenance is not performed. Indoor wires may also be used, however, in case where there is no risk of deterioration due to exposure to heat, etc. Note Specifications related to each junction are as follows. Mini-clamp connector (AN-8000EX line terminal) Conductor diameter: 0 0.4 - 0.65 mm (AWG22 - 26), Solid wire Outside diameter: 0 1.05 mm or below Clip terminal (E-7000TB) Conductor diameter: 0 0.4 - 0.8 mm (AWG20 - 26), Solid wire Outside diameter: 0 1.5 mm or below Removable terminal plug (AN-8031 MS line terminal) Conductor diameter: 0 0.4 - 1.6 mm (AWG14 - 26), Solid wire/Stranded wire External dial input terminal (AN-8031 MS) Conductor diameter: 0 0.8 - 1.3 mm (AWG16 - 20), Solid wire/Stranded wire 3.5. Relations Between Core Diameter of Cable and Maximum Cable Length Refer to the following chart as guidelines when designing the distance between the Exchange and stations so that loop resistance value becomes 170 O or less. Conductor diameter (mm) Loop resistance (Q/km) Maximum cable length between the Exchange and station. (Assuming that the loop resistance is 170 Q) 00.4 295 570 m 00.5 187 900 m 00.65 113 1.5 km 00.9 58 2.9 km 3.6. Terminal Station Connection 3.7. Terminal Plug Connection Mini-clamp connectors for line terminals and removable terminal plugs for paging output terminal are supplied with the AN-8000EX Exchange. Perform each connector connection as follows. Step 1. Strip a cable jacket of approx. 5 mm from the cable end. 5 mm Step 1. Cut off two-cable ends in equal length, and insert them securely to a cover section (transparent side) of the mini-clamp connector. Note Insert the cable without stripping the cable jacket. Note Do not solder plate on exposed inner cables when using a stranded wire. Cover (transparent side) Cable Step 2. With a pair of pliers, lightly pinch the mini-clamp cover and, after ensuring that the cable is securely inserted, firmly squeeze on the cover. Note Squeeze on the mini-clamp cover until it is correctly locked. Step 3. Insert the wired connector (plug) into the exchange's connector (socket) until it locks into place. Step 2. Loosen the terminal screws and insert the cables. Step 3. Tighten the terminal screws securely. Notes • Tug lightly on the cable to be sure that it does not pull free. If the cable pulls free, loosen the terminal screw again and reconnect from Step 2. • To avoid stripping the screws, use the screwdriver appropriate to the screws tightened into the terminal plug. Step 4. Insert the wired terminal plug into the pin header on the AN-8031 MS's PC board.
