Power
THE XL8 SYSTEM COMPONENTS SHOULD NEVER BE OPERATED WITH THE
MAINS EARTH DISCONNECTED!
Please note that the system power supplies contain LETHAL VOLTAGES greatly in
excess of the mains voltage and that its rails can produce extremely large currents that
could burn out equipment and wiring if shorted. All testing and servicing must ONLY be
carried out by approved service engineers.
This apparatus should only be operated with the power supply connected to ground via
the ground in the mains connector.
The internal power supply is of the switch mode type that automatically senses the
incoming mains voltage and will work where the nominal voltage is in the range
100VAC to 240VAC.
We strongly recommend that, for safety and to optimise the life and performance of the
equipment, the mains cable plug is removed from the power outlet when the equipment
is not to be used for extended periods of time or during electrical storms.
When removing the equipment’s electric plug from the outlet, always hold the plug
itself and not the cable. Pulling out the plug by the cable can damage it.
Never insert or remove an electric plug with wet hands.
Handling the equipment
Completely isolate the equipment electrically and disconnect all cables from the
equipment before moving it.
When lifting or moving the equipment, always take its size and weight into
consideration.
Do not insert your fingers or hand in any gaps or openings on the equipment, for
example, vents.
Avoid inserting or dropping foreign objects, such as paper, plastic, metal etc., into any
gaps or openings on the equipment, for example, vents. If this happens, turn off the
power immediately and unplug the power from the AC outlet. Then have the equipment
inspected by the manufacturer's qualified service personnel.
Installation
Before installing the equipment:
• Make sure the equipment is correctly connected to the protective earth conductor of
the mains voltage supply of the system installation through the mains lead.
• Power to the equipment must be via a fused spur.
• Power plug must be inserted in socket outlet provided with protective earth contact.
The electrical supply at the socket outlet must provide appropriate over-current
protection.
• Both the mains supply and the quality of earthing must be adequate for the
equipment.
• Before connecting up the equipment, check that the mains power supply voltage
rating corresponds with the local mains power supply. The rating of the mains power
supply voltage is printed on the equipment.
• Mount in rack only.
