Warning: this equipment must be earthed
If the plug supplied is not suitable for the power supply in your country, please consult your supplier.
UK information
The mains lead supplied with the power supply unit is already fitted with a moulded plug incorporating a 5A fuse. If it does not fit your socket-
outlet, the plug should be removed from the mains lead and safely disposed of. The flexible cord insulation should then be stripped back as
appropriate. A suitable alternative plug should then be fitted. If the replacement plug is intended to take a fuse, then a 5A fuse must be used. If
you need to replace the fuse in the mains plug supplied, then you must use a 5A fuse ASTA-approved to BS1362.
As the colours of the cores in the AC power lead of this equipment may not correspond to the coloured markings identifying the terminals
in your plug, proceed as follows:

Never use mains plugs with the fuse carrier omitted. If you lose the fuse carrier, either replace it with a carrier of the same type and
manufacturer or replace the moulded plug with another mains plug, wired as detailed above.
Keep the machine at a room temperature of +5°C to +35°C (+41° to +95° Fahrenheit) and a relative humidity of 20% to 80% (non-
condensing). As a rough guide, if you feel much too hot, cold or humid, the conditions are probably too extreme for the computer as well.
Avoid sudden extremes in temperature, exposure to direct sunlight, heat sources (e.g. electric fan heater) or rain.
Stand equipment on a rigid horizontal flat surface, allowing enough space for air to circulate when in use.
Ensure that any wires and cables are routed sensibly so that they cannot be snagged or tripped over. Don't tug or twist any wires or cables,
or use them to hang or lift any of the units.
Position the monitor at least 50cm away from other monitors (especially if back-to-back) to avoid interference.
Make sure you've read and understood any installation instructions supplied with upgrade kits before attempting to fit them. If in doubt,
contact your supplier
Keep the original packaging in case you need to transport the computer.
Keep the plastic bags contained in the packaging away from children.
The equipment shall be installed near the power outlet, which shall be readily accessible.
If you're going to move the computer, park the hard disc first.
Switch off and unplug the equipment at night, or if you're not going to use it for a few days.
Switch off and unplug the equipment and any accessories before opening the unit (e.g. to install an upgrade).
The main computer unit should be operated with the top cover (which also acts as a fire enclosure) secured, to ensure the correct airflow
through the unit.
DON'T attempt to open any display or monitor, whether supplied with the equipment or not.
DON'T drop the equipment or subject it to excessive bumping and jarring.
DON'T spill liquid on the equipment. If you do, turn the equipment off immediately and take it to your supplier for assessment.
DON'T obstruct, cover or poke objects through the ventilation openings in the computer casing or power supply
DON'T exceed the maximum power consumption of 3 watts from the expansion card slot.
DON'T balance any objects, or stand equipment weighing more than 25kg (33Ibs) on top of this equipment.
The core which is coloured green and yellow must be connected to the terminal in the plug coloured green and yellow, or marked by the
letter E or by the earth symbol
The core which is coloured blue must be connected to the terminal coloured black or marked with the letter N.
The core which is coloured brown must be connected to the terminal coloured red or marked with the letter L.
