Safety
DANGER!
Risk of injury and choking hazard for children!
Children can suffocate on packaging material and small parts. Children can
injure themselves when handling the device. Never allow children to play with
the packaging material and the device. Always store packaging material out of
the reach of babies and small children. Always dispose of packaging material
properly when it is not in use. Never allow children to use the device without
supervision. Keep small parts away from children and make sure that the device
does not shed any small parts (such knobs) that children could play with.
DANGER!
Danger to life due to electric current!
Within the device there are areas where high voltages may be present. Never
remove any covers. There are no user-serviceable parts inside. Do not use the
device when covers, safety equipment or optical components are missing or
damaged.
DANGER!
Danger to life due to electric current!
A short circuit could lead to a fire hazard and risk of death. Do not modify
the mains cable or the plug! In case of isolation damage, disconnect
immediately the power supply and arrange repair. If in doubt, seek advice from
a qualified electrician.
NOTICE!
Risk of fire due to covered vents and neighbouring heat sources!
If the vents of the device are covered or the device is operated in the
immediate vicinity of other heat sources, the device can overheat and burst
into flames. Never cover the device or the vents. Do not install the device in
the immediate vicinity of other heat sources. Never operate the device in the
immediate vicinity of naked flames.
NOTICE!
Damage to the device if operated in unsuitable ambient conditions!
The device can be damaged if it is operated in unsuitable ambient conditions.
Only operate the device indoors within the ambient conditions specified in the
“Technical specifications” chapter of this user manual. Avoid operating it in
environments with direct sunlight, heavy dirt and strong vibrations. Avoid
operating it in environments with strong temperature fluctuations. If
temperature fluctuations cannot be avoided (for example after transport in low
outside temperatures), do not switch on the device immediately. Never subject
the device to liquids or moisture. Never move the device to another location
while it is in operation. In environments with increased dirt levels (for
example due to dust, smoke, nicotine or mist): Have the device cleaned by
qualified specialists at regular intervals to prevent damage due to
overheating and other malfunctions.
NOTICE!
Damage to the device due to high voltages!
The device can be damaged if it is operated with the incorrect voltage or if
high voltage peaks occur. In the worst case, excess voltages can also cause a
risk of injury and fires. Make sure that the voltage specification on the
device matches the local power grid before plugging in the device. Only
operate the device from professionally installed mains sockets that are
protected by a residual current circuit breaker (FI). As a precaution,
disconnect the device from the power grid when storms are approaching or it
the device will not be used for a longer period.
Features
- Power supply for up to eight electrical loads with IEC sockets
- Filters to protect the connected units against interference and voltage peaks
- Resettable electronic overload fuse
- Two dimmable rack lights
- Supply voltage monitoring via tricoloured LED chain
