Safety Instructions

For safe and efficient operation, observe the guidelines given in this manual and all necessary
safety precautions. Follow the operating instructions and adhere to all warnings and safety
precautions located on the product and this manual.
Installation and service is to be performed by service persons only.
l
IPBL must be connected to a mains socket outlet with a protective earthing connection.
l
IPBL must be mounted in a Restricted Area Location (RAL) in Sweden, Finland and
l
Norway.
Ensure that the voltage and frequency of the mains power socket matches the voltage and
l
frequency inscribed on the equipment's electrical rating label.
Never install telephone wiring during a thunderstorm.
l
Note: Avoid touching or punching down the IPBS/RFP signal and power pairs as there is 48Vdc or
24Vdc present on these wires at all times.
Always install the base station conforming to relevant national installation rules.
l
Disconnect all power sources before servicing the equipment.
l
Use only approved spare parts and accessories. The operation of non-approved parts
l
cannot be guaranteed and may cause damage or danger.
Only approved power supplies according to valid editions of EN/IEC/CSA/UL/AU/NZS
l
60950 are to be used when the IPBS/RFPs are powered by local power supplies.

Protection Against Electrostatic Discharge (ESD)

Integrated circuits are sensitive to ESD.To avoid damage caused by ESD, service engineers
and other people must handle equipment and boards carefully.
Electronic equipment has become more resistive to ESD, but we see an increase of situations
where static electricity can build up. This is caused by an increasing application of man–made
fibres like nylon, acrylic, etc. which are capable of generating ESD of 10,000 Volts and more.
Walking across a nylon carpet, even for a few feet, could cause a person to be charged–up to
more than 10,000 Volts.
Under these conditions, if a system board or a (C)MOS device is touched it could easily be
damaged. Although the device may not be totally defective, it is often degraded, causing it to fail
at a later date without apparent reason.
To make sure that equipment and parts are well protected during shipment, special packaging
materials are utilized. System boards will be shipped in anti–static bags and (C)MOS devices
and other sensitive parts in small shielded boxes.
