2. Description of mechanical parts

2.1. Base (chassis)

The base carries the other parts. The power supply (plug 230V/AC + power
switch) is mounted in the upper right part. The upper left + lower left part is intended
for fitting the extender. The strip with holes in the bottom part is intended for fitting
serial and blanking platelets. The display is fixed in the upper part in the centre.

2.2. PBX cover

The plastic cover bears a sticker with a transparent window for the display.

The cover is fitted on the chassis by fitting into two holes in the upper part of
the plastic and is secured by two extendable “pegs” into the lower part of the plastic.

When dismantling the cover, first press (using an appropriate tool) both
extendable “pegs”, whereby you free the cover and then remove the cover.

Installation manual

B1 - Lithium battery holder. We recommend replacement when the voltage is lower than 2.5

V, or at least once every three years. We recommend the batteries be replaced with the
PBX off. Before replacement we recommend saving the program of the PBX and the
accounting data in a PC. After replacement check the date, time and program of the
PBX and, if not correct, make the correct adjustment. Never change the batteries when
the PBX is on.
WARNING! Use only a tool made from insulating material for replacement!!!

Note:

J18 – the connector is intended for connecting the PBX with a PC. It thus allows
the programming of the PBX using the program OMEGA Lite - PROGRAM, detailed
display of operation using program OMEGA Lite - PANEL, for connection of XAPI
Server, etc.

The serial port includes an insulating DC/DC converter of its own and, by
optical signal transmission, provides galvanic isolation of the serial port from the
PBX with a guaranteed insulation strength of 500 V.

This solution has the following advantages:

• Helps transmit data over long distances

• Improves data transmission reliability (resistance to disruption)

• Enables communication with a PC powered from a different power supply section

(for example, from a different phase or central UPS)

• Improves overvoltage resistance of the input
For connection with a PC, especially over a greater distance, a normal (i.e., cross-

over) four-wire telephone cord with RJ-12 terminals is normally used instead of a
special “serial cable”.

3.2. Power supply

As the Power supply a power supply module with open construction and with
output voltage of +24VDC/2.7A (connector J2) is used. One integral part of the
supply is the cooler, which is designed for an upright working position of the PBX. It
is not allowed to operate the PBX in a horizontal position (lying on a table etc). The
source is distinguished in particular by the simplicity of connection, which is a
guarantee of the source’s maximum reliability. The source has an overvoltage fuse
(F1) F4A/250V. The power goes to connector J1.

3.3. Source – mains part _ ringing transformer

The mains part is attached using a detachable mains lead (so-called EURO
socket).

Installation manual

The lever switch located on the right side of the chassis serves for switching
the power on and off.

The mains part is protected against contact with live parts by a cover which
also covers the actual power source.

The ringing voltage with a frequency of 50 Hz comes directly from the mains by
a so-called ringing transformer. The ringing transformer is protected from shorting by
fuse T0.063A.

WARNING! This part is connected to the mains power and works with voltage which

is dangerous to life. All repairs and replacements of these
parts are only made at the manufacturer!! Only the
following handling is allowed:

WARNING!

Disconnect from

mains before handling!

• Mains lead connection and disconnection
Always perform this handling with the PBX disconnected

from the mains!!!

!!! Note: The source can be connected to equipment of the type UPS ( backup
source).
