4. INSTALLATION
4.1 INTRODUCTION
As with any sophisticated communications device, installation of the Aria-34e System requires
the care and fore-thought of a competent technician. Installation proceeds in 4 major steps:
- Site Preparation
- KSU Installation
- PCB Installation
- System Wiring
4.2 SITE PLANNING
The Aria-34e key telephone system must not be subjected to harsh environmental conditions.
To ensure easy servicing and reliable operation, several factors must be considered when
planning the system installation. Always remember the following before installing the KSU and
wiring:
a) The BKSU and EKSU are designed for wall mounting or installation on a solid
backboard.
b) A 240V 10 Amp separately fused GPO is required. The GPO earth terminal must be
bonded to building Protective Earth (PE).
c) The KSU should be centrally located and care should be taken to stay within prescribed
cable lengths.
d) Thought should be given to the location of telephone conduits or cable runs.
e) A well-ventilated area having a temperature range of 0-50 degree C with a
recommended temperature range of 20-26 degree C and a humidity range of 10-95%
(non-condensing).
f) Lighting and accessibility to the KSU equipment for servicing.
g) Protection from flooding, flammable materials, excessive dust and vibration.
h) Avoid proximity of radio transmitting equipment, arc-welding devices, copy machines,
personal computers and other electrical equipment that are capable of generating
electrical interference.
Note: Some Computer terminals emit high levels if EMI! Beware!

4.5 KSU EQUIPMENT MOUNTING
The KSU equipment is designed for wall mounting according to Figure 1.
Figure 1. Aria-34e KSU Mounting
The KSU must not be mounted directly on a masonry or dry walled surface. A wooden
backboard(plywood or pressed board) of sufficient size should be attached to the wall for the
KSU to be mounted upon. The KSU mounting template should be used to identify screw hole
locations. It is important that the KSU and MDF connecting blocks be mounted on the
backboard. See

4.5.1 KSU GROUNDING
The Aria-34e Series of Digital Key Telephone Systems do not provide separate earth terminal
for PE (Protective Earth) and TRC (Telecom Reference Conductor). The Protective Earth
connection is via the 240VAC GPO and power cord. It is absolutely essential that the Protective
Earth terminal of the 240VAC GPO is bonded to the building protective earth system, as verified
by an electrician.
A separate TRC MUST NOT be installed.
The TRC is provided via a linking to the PE within the KSU equipment. The TRC/PE linking is
automatically engaged as each board is plugged into the KSU.
WARNING
ALL COMMUNICATION NETWORK CONNECTIONS MUST BE DISCONNECTED
FROM THE SYSTEM BEFORE THE AC POWER LEAD CAN BE REMOVED FROM
THE SYSTEM OR THE G.P.O
THE MAINS POWER LEAD MUST BE PLUGGED INTO THE G.P.O BEFORE
MAKING ANY CONNECTIONS TO THE NETWORK.
4.5.2 POWER LINE SURGE PROTECTION
It is recommended that the Aria-34e system should be equipped with a power-line transient
surge protection device at the 240VAC GPO. Systems equipped with such devices are more
resistant to damage from power line surges than unprotected systems. Power line surges often
occur during switching operations and especially during violent thunderstorm activity.
Installation of a surge protector meeting the specifications described here will prevent or
minimise the damage from power-line surges. The protector should be fast acting and capable of
protecting against transients greater than 400 volts.
4.5.3 INSTALLING POWER SUPPLY UNIT
The Power Supply Unit mounted within the system supplies power for the boards, key stations,
telephones and battery charging. The power unit will be installed during production.
The PSU circuitry is located on the right hand side in the base of the KSU. The recommended
operating conditions are:
Input Voltage
Fuse
220V ~ 240V
T1 A H 250V
Ensure the PSU is connected as in Figure 3.

other user adjustments.
4.5.5 BATTERY BACKUP INSTALLATION
The system can be backed-up by external batteries in case of 240VAC power failure. The
connector for the external battery is located on the base of the KSU. Connection from the Power
Unit to the external battery is via a GoldStar cable-assembly designed for this purpose.
a) A separate external 24 Volt DC battery or two separate 12 Volt DC batteries should be
provided.
b) Two 12 V DC batteries are serially connected to the BAT.+,- lead of AC/DC power
supply for the basic cabinet. See following Figure 4.
c) The battery is charged by the charging circuit in the AC/DC power supply during
normal system operation. During AC power loss, the battery will supply power for the
system without power interruption.
d) The chart below gives the approximate backup time for the Aria-34e series.

4.5.6 RING GENERATOR INSTALLATION
The Ring Generator Unit is needed in the Aria-34e KSU when any Single Line Telephone
Devices are supported. This includes a modem, fax or an industry standard AUSTEL approved
SLT. These devices interface with the 4SLI or SLIB cards in the system. The RGU is used to
provide ringing and message wait source power for the SLT devices.
The RGU is mounted on the bottom right side of the KSU with two (2) screws and is connected
to the Main Board Unit (MBU) on CN5 connector. A ferrite core (supplied) must be fitted to the
connecting cable from the RGU to the MBU for EMI suppression.

4.5.7 BOARD INSTALLATION
WARNING: The power must be OFF when removing/installing all boards.
The printed circuit boards used to configure the system are referred to as PCB's.
The PCB's contain digital circuitry which, while extremely reliable, can be damaged by exposure
to excessive static. Please follow these precautions to when handling the boards minimise risk of
damage.
1. 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.
2. Always use a ground wrist strip when handling PCB's. This will minimise the
possibility of static damage.
3. Never lay an unprotected PCB on a carpeted surface.
Note: The 3-Pin Plug must be plugged into the 240 VAC GPO to provide the system
earth.
The system provides Universal slots so that the CO line/Telephone ratio can be configured freely
up to the maximum configuration according to the user's requirement and system limitations.
To install a PCB, hold the card on the mounting knobs and, with the component side facing up,
insert the card into the system‟s card edge connector firmly and tighten the screw(s). To remove
