3. General Safety Instructions
Warning
Do not install devices in any of the following places:
• where the units are permanently exposed to direct sunlight.
• near other heat sources or open fire.
• where the airflow for cooling is blocked.
• where the devices are exposed to high moisture.
• where the devices are exposed to strong vibrations and dust.
Power supply
Before connecting to the power supply system, check if the local voltage matches the voltage
marked on the device. The device then needs to be adapted to the required mains voltage by
Kling & Freitag or an authorized service centre. Connect the device under any circumstances,
to an unauthorized power supply source. This could irreparably ruin the device.
Make sure that the power outlet supplies a ground connector, which must be connected to
the device via the PE conductor of the power cord!
All devices interconnected over signal lines with connection to a protective earth must be
connected to a common protective earth. If not, there is a risk of an electric shock or the
destruction of the connected equipment. The power plug must always be used to disconnect
from the power supply. Furthermore, the power plug must be easily accessible for use at all
times.
Protection of electrical cables
Power cables should be routed so that they are protected against impact damage and tensile
stress caused by jamming between objects.
Transportation
When transporting the device, make sure that it is protected from vibrations.
Cleaning
The equipment should only be cleaned with a damp cloth when it is not plugged in.
Pauses in use
The power cord should be disconnected from the power source during longer pauses in use.
Intrusion of liquids
It should always be ensured that no liquids get into the device.
