WARNING: TO REDUCE THE RISK OF FIRE
OR ELECTRIC SHOCK, DO NOT EXPOSE THIS
APPARATUS TO RAIN OR MOISTURE
This apparatus uses a single-pole power
switch. As a result it is not isolated from AC
mains power when switched off at the rear
panel. The apparatus may be isolated from
mains power either by unplugging the power
connector from the rear of the unit, or by
unplugging the connector at the opposing
end of the power cord or cable from its supply
outlet. As a result, either or both of these
connectors should remain accessible.
Safety warnings
• Do not expose the unit to dripping or splashing.
• Do not place any object filled with liquid, such
as a vase, on the unit.
• Do not place naked flame sources, such as
lighted candles, on the unit.
To avoid interference
Do not position the unit:
• Near strong magnetic radiation.
• Near to a television, or where connecting cables
may be subject to or cause interference.
To avoid overheating

ensure sufficient ventilation.
Do not position the product:

than in a properly ventilated rack, as the heat it
generates may damage the other products.
The sides and top of the C51 case contain
venting holes for the internal heatsinks which
