PROTON 206/308 V1 System Manual 55
• It is advisable that the system should be installed away from any source of electromagnetic noise such as
any radio equipment, heavy transformers, faulty electric chokes of tube lights, any device having a faulty coil
etc. This will reduce any problem arising due to electromagnetic effect.
Cabling
• Decide different places at which you want to give the stations the shortest possible cabling route to that
location.
• Always ensure that you have separate cable conduits for both electrical and telephone cables.
• The wires in the MDF should be inserted only after removing the insulation properly (1.0cm approx.). Please
do not double the cable before inserting in the MDF. Select a good quality telephone cable (with 0.5mm
conductor dia) for internal cabling.
• For all over-head cabling, good quality drop wire must be used. In case you have any problem please take
help of an expert wireman.
• Avoid long length cables and at the same time keep number of joints to a minimum i.e. strike a balance
between the two. This will help you to find out a cable fault easily.
• Single core cable is preferred instead of multi-core cable.
Power Supply
• The PROTON 206/308 operates on 90-265VAC, 47-63Hz Universal Power Supply. Arrange for a separate
power point and switch, close to the system. Power Supply for the PBX must be separate from other heavy
electrical loads like Air-conditioners, Heaters, Welding machines, Electrical motors, etc.
• If the supply is not stable, use of a good CVT is recommended.
Earth (Ground)
• Proper earth is vital for safety of the personnel and the system.
• Good electrical earth prevents electric shock to the personnel.
Telephones
• The PBX is capable of working with all standard telephones: Rotary phone, Pulse-tone switchable push-
button phone, Feature phone and Cord-less phone.
• It is not necessary to buy all new phones. You may also hook up your existing old telephones.
Trunk lines
• Connect the trunk lines to the system.
Installation
• Unpack the box. Get satisfied with the contents and the condition of all the parts. In case of short supply or
damaged parts, please contact the source from where you purchased the system immediately.
• Don’t power the system.
• Fix the system on the selected site. Please refer “PROTON-206/308 Mechanical Drawing” at the end of this
topic for exact mechanical dimensions.
• Check the voltage at the power point from where the supply is to be accessed. It should be as specified. It is
desirable to use a good quality power-conditioning device such as CVT.
• Earth the system properly.
• Connect all the station and trunk cables on the MDF of the system. Please note that the system provides
push-type connectors on the MDF for station and trunk wires. Remove about 1cm of the insulation for proper
connections of the field wires to the MDF connectors.
• Tag each wire pair with respective station or trunk number. (Different colour tags for trunk and station can be
used for better identification).
• Connect power cord of the system to the power supply. Ensure proper contacts.
