Precaution
Please read the following notes concerning installation and connection before installing the system.
!Never attempt to insert wires, pins, etc. into the vents or other holes of this unit.
!If there is any trouble, disconnect the unit from the telephone line. Plug the telephone directly to the
telephone line. If the telephone operates properly, do not reconnect the unit to the line until the trouble
has been repaired. If the telephone does not operate properly, the chances are that the trouble is in
the telephone system, and not in the unit.
!Do not use benzine, thinner, or the like, or any abrasive powder to clean the cabinet. Wipe it with a
soft cloth.
WARNING
WHEN A FAILURE OCCURS WHICH RESULTS IN THE INTERNAL PARTS BECOMING
ACCESSIBLE, DISCONNECT THE POWER SUPPLY CORD IMMEDIATELY AND RETURN
THIS UNIT TO YOUR DEALER.
DISCONNECT THE TELECOM CONNECTION BEFORE DISCONNECTING THE POWER
CONNECTION PRIOR TO RELOCATING THE EQUIPMENT, AND RECONNECT THE
POWER FIRST.
THIS UNIT IS EQUIPPED WITH AN EARTHING CONTACT PLUG FOR SAFETY REASONS
THIS PLUG MUST ONLY BE CONNECTED TO AN EARNING CONTACT SOCKET WHICH
HAS BEEN INSTALLED ACCORDING TO REGULATIONS.
THE POWER SOCKET WALL OUTLET SHOULD BE LOCATED NEAR THIS EQUIPMENT
AND BE EASILY ACCESSIBLE.
TO PREVENT FIRE OR SHOCK HAZARD, DO NOT EXPOSE THIS PRODUCT TO RAIN OR
ANY TYPE OF MOISTURE.
Make sure to keep the following instruction when exchange the Fuse.
!When you change the Fuses on the Power Supply, Disconnect the Power connection first and
exchange the Fuses.
Caution !! Double Pole/Neutral Fusing

Precaution
Safety Installation Instructions
When installing telephone wiring, basic safety precautions should always be followed to reduce the risk
of fire, electric shock and injury to people, including the following:
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 non-insulated telephone wires or terminals unless the telephone line has been
disconnected at the network interface.
4. Use caution when installing or modifying telephone lines.
Installation Precautions
This set is exclusively made for wall mounting only. Avoid installing in the following places.
(Doing so may result malfunction, noise or discoloration.)
1. In direct sunlight and hot, cold, or humid places. (Temperature range: 0°C-45°C/32°F- 113°F)
2. Sulfuric gases produced in areas where there are thermal springs, etc., may damage the
equipment or contacts.
3. Places in which shocks or vibrations are frequent or strong.
4. Dusty places, or places where water or oil may come into contact with the unit.
5. Near high-frequency generating devices such as sewing machines or electric welders.
6. On or near computers telexes, or other office equipment, as well as microwave ovens or air
conditioners, (It is preferable not to install in the same room with the above equipment.)
7. Install at least 1.8 m (6 feet) from radios and televisions. (both the main unit and a key telephone)
8. Do not obstruct area around the main unit (for reasons of maintenance and inspection - be
especially careful to allow space for cooling above and at the sides of the main unit).
Wiring Precautions
Make sure to keep the following instructions when wiring.
1. Do not wire the telephone cable in parallel with an AC power source, computer, telex, etc. If the
cables are run near those wires, shield the cables with metal tubing or use shielded cables and
ground the shields.
2. If cables are run on the floor, use protectors or the like to protect the wires where they may be
stepped on. Avoid wiring under carpets.
3. Avoid using the same power supply outlet for computers, telexes, and other office equipment.
Otherwise, the TX-Z2824's system operation may be interrupted by the induction noise from such
equipment.
4. Please use one pair telephone wire for extension connection of (telephone) equipment such as
standard telephones, answering machines, etc., except key telephones.
5. The AC cord must be plugged off during wiring. After all the wiring are completed, plug the AC
cord into an AC outlet.
6. Wiring error may cause the system to operate improperly.
7. If an extension does not operate properly, disconnect the telephone from the extension line and
then connect again, or plug off the AC cord of the system and then on again.
8. Use twisted pair cable for Trunk line connection.
9. Trunk Lines should be installed with lightning protectors.
10. The aerial distribution wiring is not allowed.

Installing the Main Equipment (Wall Mounting)
The Main Equipment should be installed in a clean, dry, centrally-located spot (such as a closet), where it
is out of direct sunlight. The area should be free of moisture (water, dampness, etc.), and away from any
equipment which might vibrate. You should choose a location that is well-ventilated, where the
temperature does not exceed that of a normal room.
Step 1: Before wall mounting the TX-Z2824 Main Equipment, the top cover of Main Equipment must be
removed. Loosen the two screws and remove the top cover as illustration.
Step 2: Tack-fasten two of the four wood screws (provided with Main Equipment) on the wall at about
320 mm apart.

Installing the Main Equipment (Wall Mounting)
Step 3: Place the two holes of the main unit over the tacked wood screws to hang the Main Equipment on
the wall and then fully tighten the wood screws.
Step 4: Fasten another two screws on the wall through the two bottom holes of the Main Equipment.
PRECAUTIONARY SAFEGUARDS
1. Never install the Main Equipment where it may be exposed to water (near a bathtub, pool, sink, etc.).
2. Never mount the Main Equipment on an unstable surface, where it might fall.
3. Never block the vents on the Main Equipment. These vents prevent the unit from overheating.
Proper ventilation must be supplied for the unit.
4. Never place any objects inside the vents of the Main Equipment.

Grounding Requirement
"The Card Locations
The card locations for the Main Equipment are shown in the following illustration.
"Grounding Requirement
The main equipment must be properly grounded. If circuit ground is not available at the dedicated AC
outlet, the following steps should be taken:
Step1: Provide a suitable ground in accordance with the local operating telephone company procedures.
Step2: Where a ground is used, a grounding terminal is provided on the Main Equipment.

Connector Assembly
Trunk Line Connection
"Connector Assembly
When connecting the wiring cables to the connectors mounted on the units. Insert the wires of each cable
into the connector and insert this connector to female connector on the unit (see illustration).
Step 1: As indicated in the illustration, insert twisted or quad telephone wire (0.4 to 0.65 mm φ) into the
upper section of the connector. Ensure that the lead wire ends do not protrude beyond the rear surface of
the connector.
Step 2: Install the upper section of connector over the lower, and then compress the assembled
connector with pliers or the like. Verify that the upper section of connector will not come off the lower
section.
"Trunk Line Connection
The Trunk (CO/PBX) lines shall be connected as illustration. Make connection from Telecom provided
connector to one of the connector on the 408M-M1 or 208E-M1 units labeled COCN.
The TX-Z2824 system can be installed eight Trunk lines maximum. The basic system is equipped to
accept four Trunk lines. If two expansion units (NX8E-208M-A1 PCB) are installed, four more Trunk lines
may be installed (see System Configuration Table).

Cable Routing and Cramping
Installing Expansion PCBs
"Cable Routing and Cramping
All cabling should exit from the right side of
the Main Equipment. Route and cramp the
cable for the Main Equipment as illustrated
on the right side.
"Installing Expansion PCBs
The NX8E-208E-M1 PCB is CO/PBX and station interface card which provides two CO/PBX interface,
eight station interface. The NX8E-008E-M1 PCB is station interface card which provides eight station
