ACHTUNG
Failure to observe this safety information may result in personal injury due

HINWEIS
Read this operating manual attentively! It contains important information about
installation, ambient conditions and maintenance of the device. Keep this operating manual for
future use and for handover in the event of a change of owner or operator. A PDF version of this
manual is available to download on the ASTRO website (there may be a more recent version).
Check the packaging and the device for transport damage immediately. Do not start operation of
a device that has been damaged.
Transporting the device by the power cable may damage the mains cable or the strain relief, and
is therefore not permitted.
Installation and operation
The device may only be installed and operated by qualified persons (in accordance with EN
62368-1) or by persons who have been instructed by qualified persons. Maintenance work may
only be carried out by qualified service personnel.
An installation site must be provided that prevents children from playing with the device and its
connections.
In order to operate the U 100-230 unit (protection class I), it must be connected to mains sockets
with a protective earth conductor.
The electrical connection conditions must correspond to the specifications on the device type
plate.
To avoid damage due to overheating, the device may only be installed on horizontal surfaces. The
device is, where possible, intended for operation in metallically conductive 19" racks with sufficient
air convection to ensure that the maximum permissible ambient temperature for the device is
adhered to. The installation surface should be non-flammable.
The ambient temperatures specified in the technical data must be complied with, even when
climatic conditions change (e.g. due to sunlight). If the device overheats, the insulation used to
isolate the mains voltage may be damaged.
The device and its cable may only be operated away from radiant heat and other sources of heat.
To avoid trapped heat, ensure there is good ventilation on all sides (minimum interval of 20 cm to
other objects). Installing the device in a niche or covering the ventilation openings is not permitted.
No objects may be placed on the device.
The subscriber network must be earthed in accordance with EN 60728-11, and must remain
earthed even when the device is removed. Furthermore, the earth connection on the device can
be used. Devices within hand's reach must be integrated into the potential equalisation together.
Operating the device without an earth conductor, without earthing the device or without using
device potential equalisation is not permitted.
