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!

4.3 INSTALLATION PLANNING
a) Aria-34e system has been designed as a plug-in card/unit type system to provide up to
38 port user capacity, with a maximum of 34 extension ports or CO Line ports.
b) Plug-in boards such as LCOB, 4LCO, ETIB, DTIB, SLIB, 4SLI, DVIB can be installed
in the system as required to expand system capacity.
c) New software packages with enhanced features will be commercially available as
advised by Aria Communications.
4.4 UNPACKING THE KSU
a) Remove the Key Service Unit from shipping carton and stand it upright on the level
working surface with the cover facing forward. Turn the 4 screws on the sides of the
cabinet and remove. Remove all packing materials from inside the KSU and inspect for
shipping damage. The KSU should be empty when received. Inside the KSU packing
should be a mounting template. The mounting template includes mounting dimensions
for the expansion cabinet.
b) The items listed below are needed to have an operating system. The number and type of
plug-in cards needed depends on the size of the system being installed.
KSU
Desired Interface Cards
1 x 27 Way Krone Frame With Lid
Installation Tails
Digital Keystation(s).

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

Figure 2. for a typical system mounting dimensions. Insert 4 screws (#10 or larger) into the
backboard and tighten enough to hold the weight of the KSU. When the KSU is in position, the
screws should be tightened and the KSU should be securely mounted.

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.

Figure 3. PSU Connection
4.5.4 POWER VOLTAGE SELECT
The Power Supply Unit is set to 240VAC operation at the factory prior to shipping. There are no
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.
