3. WIRING

3.1. Connection Diagram

3.2. The Type of Cables

The types of cables are to be determined according to the following conditions.

• Twisted pair wires (such as those used for electronic pushbutton 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 (N-8000EX line terminal)

Conductor diameter: ø 0.4 – 0.65 mm (AWG22 – 26),

Solid wire

Outside diameter: ø 1.05 mm or below

Clip terminal (E-7000TB)

Conductor diameter: ø 0.4 – 0.8 mm (AWG20 – 26), Solid

wire

Outside diameter: ø 1.5 mm or below

3.3. Relations Between Core Diameter of Cable and Maximum Cable Length

Referring to the following chart as guidelines, design the distance between the Exchange and stations so that loop resistance value becomes 170 Ω or less.

3.4. Mini-Clamp Connector Connection

Mini-clamp connectors for line terminals are supplied with the N-8000EX Exchange. Connect the mini-clamp connector to a cable using a commercially available tool (pliers).

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.

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.

1. WALL MOUNTING

The station can be mounted on a wall using an optional YC-290 wall mounting bracket. The YC-290 can be installed to JIS standard one gang switch box.

1.1. Mounting Example

Step 1. Install the YC-290 Wall mounting bracket to the wall.

Notes

• Use appropriate screws for the construction of wall.

• Wooden screws 3.5 x 20 are supplied with the YC-290.

• No fitting screws for switch box are supplied.

Step 2. Hang the station on the Wall mounting bracket hook

to install. Push down the station main body in the direction indicated by the arrow.

2. DESK-TOP INSTALLATION

In desktop installations, the front operation panel can be inclined 16˚ from the desk surface for easier operation by attaching the YC-290 Wall Mounting Bracket to its bottom surface.

2.1. Mounting Example

Hang the Wall mounting bracket hook on the station's wall bracket mounting slot to install. Push up the Wall mounting bracket in the direction indicated by the arrow.

This Master Station is designed to connect to the IP Intercom Exchange, and provides hands-free conversation of high sound quality. With its space-saving design, this Master Station features the same functions as the Standard Master Station. Using an optional YC-290 Wall Mounting Bracket, this station can be mounted on a wall, or tilted for easy key operation when used on a desktop.

Warning

This is a class A product. In a domestic environment this product may cause radio interference in which case the user may be required to take adequate measures.
