SAFETY AND REGULATORY NOTICES
Power
Information in the Owner’s Handbook relating to connection to the AC
power supply may not apply outside the United Kingdom.
The computer uses a safety ground and must be earthed. The system unit
AC power supply cable is its ‘disconnect device’. Ensure that the system unit
is positioned close to the AC power outlet, and that the plug is easily
accessible.
The power supply within the FT4200 server automatically sets itself to the
appropriate voltage, there is no voltage selector switch. It is advisable to
avoid subjecting the power supply to voltages outside the ranges 100-120V
AC and 220-240V AC, (50/60 Hz).
To prevent fire and electric shock, do not expose any part of the computer to
rain or moisture.
Shut down the operation of the computer as described in the Owner’s
Handbook, turn off the battery isolator switch and unplug the power supply
cable before moving the system unit, cleaning the computer or removing the
side panels. An exception to this is removing the side panels before hot-
plugging a hard disk drive.
Power cord requirements
The AC power supply cable packed with the computer complies with the
safety standards applicable in the country in which it is first sold. Use only
this power supply cable.
Do not substitute a power supply cable from any other equipment.
If you wish to use the computer in another country, you must ensure that
you use an AC power supply cable and AC plug which complies with the
safety standards of that country.
The power supply cable fittings should bear the certification mark of the agency
responsible for evaluation within the country of use. Refer to your authorised
supplier if you ever need additional or alternative power supply cables.

SAFETY/2
Laser
Any fitted CD-ROM drive contains a laser system which is harmful to the
eyes, and is classified as a CLASS 1 LASER PRODUCT according to
IEC825 Radiation Safety of Laser Products (Equipment Classification:
Requirements & User's Guide).
CLASS 1
LASER PRODUCT TO IEC 825
LASER KLASS 1
PRODUKT NACH IEC 825
The CLASS 1 LASER PRODUCT warning label, bearing similar
information to the sample above and in high visibility colours, is located on
the CD-ROM unit.
Do not attempt to disassemble the CD-ROM drive; if a fault occurs, call an
authorised maintainer. Use the CD-ROM drive only as described in this
manual. Failure to do so may result in exposure to hazardous radiation.
Ergonomic
When positioning the system unit, monitor and keyboard, take into account
any local or national regulations relating to ergonomic requirements.
Batteries
Small batteries
This product contains a replaceable lithium battery. Do not use a metal or
other conductive implement to remove the battery. If a short-circuit is
accidentally made between its positive and negative terminals, it may cause
the battery to explode.
Replace a discharged battery with one of the same type. Another type may
explode or ignite. Dispose of a discharged battery promptly and in
accordance with the manufacturer’s instructions.
The battery’s average life is between 3 and 5 years. Do not recharge,
disassemble or incinerate. Keep away from children. If in any doubt, contact
your supplier or an authorised maintainer.
UPS battery pack
The UPS is equipped with a replaceable battery pack. It will provide electric
power for your system for a specific period of time, depending on how many
hard disks or other devices are installed.
The battery pack contains lead acid batteries. In the EEC the directive
91/157/EEC (plus subsequent amendment 93/86/EEC) designates
batteries containing lead to be handled as a dangerous substance.
Similar regulations will apply in other countries.
As a result, the battery pack must only be removed by a qualified electrician
and must not be disposed of in domestic waste.

IMPORTANT
Power Cable Connections - UK ONLY
This equipment is supplied with an AC power lead that has a non-removable
moulded plug. If the AC supply outlets to be used are not suitable for the
lead supplied with this computer, a new complete and suitable power lead
should be obtained. If this is not possible, the existing plug should be cut off
and the following guidelines observed:
WarningWarning
The plug severed from the mains lead must be destroyed, as a plug with the bared
flexible cord is extremely hazardous if engaged in a live socket outlet.
The following wiring information should be employed when adding any
replacement plug.
The wires in the power lead are coloured in accordance with the following code:
Green and Yellow Earth
Blue Neutral
Brown Live
The colours of the wires in the mains lead supplied with this computer may
not correspond with the markings identifying the terminals in your plug,
proceed as follows:
The wire which is coloured green-and-yellow must be connected to the
terminal in the plug which is marked with the letter E, or by the earth
symbol or coloured green or green-and-yellow.
WARNINGWARNING
THIS APPLIANCE MUST BE EARTHED.
The wire which is coloured blue must be connected to the terminal which is
marked with the letter Nor coloured black. The wire which is coloured
brown must be connected to the terminal which is marked with the letter L
or coloured red.
Always replace the fuse with one of the same type and rating, always replace
the fuse cover, never use the plug with the fuse cover omitted.
Replace with same colour fuse cover only. Replacement fuse covers may be
obtained from your dealer.
This diagram shows the wiring inside the moulded plug. Use it as a guideline if
you need to re-fit a plug of a similar type to the AC lead.
