Installing the System
Precautions:
Before installing the System, please read the following precautions carefully:
• Do not open the system in power-ON condition.
• Do not plug/unplug any card in power-ON condition. This may damage the system. Warranty does not cover
such damages.
• The Vision uses CMOS parts. These parts are sensitive to electro-static discharges. Observe anti static
rules strictly.
• Do not install this product near water, for example near a bathtub, washing bowl, kitchen sink, laundry tub,
swimming pool etc.
• Slots on enclosure are for proper ventilation. They will protect the system from overheating. Never cover the
slots.
• Never place this product on heated place or any other equipment.
• Never push objects of any kind inside this product. This may short-circuit various parts.
• Operate these products only with 90-265VAC, 47-63Hz supply and if you are not sure about supply voltage,
contact authorized dealer. It is advisable to give proper, stabilized power.
• This product is equipped with a plug having a third (ground) pin, which fits only into a grounding-type outlet.
This is a safety feature. If you are unable to insert the plug into the outlet, ask an electrician to replace the
obsolete outlet. Do not defeat the purpose of the grounding type plug.
• Unplug this product from electric wall outlet in following cases and contact authorized service personnel.
• Liquid spills on to the product.
• Product exposed to rain or water.
• Product does not operate normally by following operating instructions.
• Product dropped from height.
• Product exhibits unusual change in performance.

• Avoid using telephone other than a cordless type during an electric storm. There may be a remote risk of
electric shock from lightening.
• Never use a telephone to report gas leaks if it is near to gas leak.
• Do not touch non-insulated telephone wires or terminals before disconnecting at the network interface.
• Please connect a Telecom earth to the system (to the port marked ‘ETH’ on the MDF).
• The protection device, GDT protects the system efficiently only if it is provided good telecom earth. Please
note that protection device protects the system, however they do not guarantee 100% protection from
lighting storm, induced voltages, etc. Please note that warranty does not cover such damages.
• Please note that these products are designed to work efficiently at temperature ranging from 0
o
C to 45
o
C
(32
o
to 113
o
Fahrenheit) with 95% relative humidity, non-condensing.
Site Selection
• The Vision should always be installed at a place equi-distant from all the stations. This reduces the cabling
cost and also makes cabling network less complicated.
• It should preferably be installed at 3.5 feet height (approx.) in airy, dust free and moisture free place. An
installation at this height makes preventive or curative maintenance task easy.
•
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
• Select a good quality telephone cable (with 0.5 mm conductor diameter) for internal cabling as well as for
over-head cabling.
• Ensure separate cable conduits for both electrical and telephone cables.
• Take care that cables are not left open on the ground where they may get damaged due to entanglement in
