Safety instructions
Danger!
Overheating or overvoltages (caused by lightning striking the
mains supply etc.) can cause units with a mains connection to
catch fire!
Always set up the unit in a well-ventilated place! Make sure that
the air vents of the unit are not covered or blocked! Never stack
more than two units directly one above the other! Do not set up
the unit near any heat sources and never expose the unit to
2
direct sunlight (see page 15)! Use an overvoltage protection
or, during a thunderstorm, disconnect the unit from the mains!
Warning!
If you open units or use damaged mains cables, you can
receive a dangerous electric shock!
Never open the unit and only use undamaged mains cables!
If a unit should be defective, repair must be carried out by
authorized personnel! If units are opened by you in breach
of this instruction, the warranty becomes null and void.
Warning!
If units and cables are set up improperly, persons can be
injured or units can be damaged!
Set up the unit on an even surface or mount it into a rack!
Lay the cables in such a way that no-one can stumble over
them!
Attention!
If liquids or small parts which conduct electricity find their
way into the interior or to the sockets of the unit, this can
cause a short-circuit which may damage the unit!
Keep liquids and small parts which conduct electricity away
from the unit! Use a damp cloth for cleaning the unit. Do not
use any solvents or cleansing agents!
Attention!
The AC 3000 contains mechanically moving parts (fans).
Since dust and pollution can impair their function, you should
regularly check the fans for proper operation and clean out
any dust if necessary. The failure of one or several fans can
cause overheating and permanent damage to the unit.
