Intended use
OperatingmanualHVB21,HVB31 a.HVB32-Version 01-2021A
Intended use
The HVB 21, HVB 31 and HVB 32 are universal broadband ampli-
fiers for bidirectional building distribution and broadband communi-
cation systems. They are exclusively designed for signal
amplification in unidirectional and bidirectional distribution systems
in single-family and multi-family dwellings.
Modification of the devices or use for any other purpose is not
permitted and will immediately void any guarantee provided by the

Important safety information
OperatingmanualHVB21,HVB 31 a.HVB32 - Version01-2021Apage 8
Important safety information
To avoid any potential risks to the greatest extent possible, you
must observe the following safety information:
ATTENTION: Failure to observe this safety
information may result in physical injury due to electrical
and thermal dangers!
Intended use
Only use the device at approved operating sites and under
approved ambient conditions (as described in the following),
and only for the purpose described in the section “Proper use”.
Before operating the device
NOTE: Read this operating manual through carefully!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 can
be downloaded on the ASTRO website (there may be a more
recent version).
Check the packaging and the device for transport damage
immediately. Do not operate a device that has been damaged.
Carrying the device by the power cable may damage the
power 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.
The electrical connection conditions must correspond to the
specifications on the device type plate.

Important safety information
OperatingmanualHVB21,HVB31 a.HVB32-Version 01-2021A
To avoid damage due to overheating, the device may only be
installed on vertical surfaces. The connection for the power
supply unit must pointto theright.Theinstallation basis should
be level and non-flammable. Operating position: Device
vertical, with power supply output on the right.
The permitted ambient temperatures specified in the technical
data must be complied with. If the device overheats, the insu-
lation used to insulate 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 recesses or covering the installation location, for
example using curtains, is not permitted. Ventilation openings
must not be covered.
If the device is installed in a cabinet, ensure adequate air
convection is possible to avoid exceeding the maximum
permitted ambient temperature.
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
isremoved. In addition,the earth connectiononthedevicecan
be used. Devices within hand’s reach must also be integrated
into the potential
equalisation. Operating the device without an earth conductor,
without earthing the device or without equipotential bonding of
the device is not permitted.
The device does not feature protection against water and may
therefore only be operated and connected in dry rooms. The
device must not be exposed to spraying water, dripping water,
condensation or similar sources of moisture.
The electrical system supplying current to the device, such as
a building installation, must incorporate protective devices
against excessive currents, earth faults and short-circuits in
accordance with EN 62368-1.
Caution! Hot surface: Housing components near the cooling
fins at the rear or the cooling fins themselves may become
very hot. Do not touch these parts.
The power supply plug is used to disconnect the device from
the mains voltage for servicing and in the event of danger and
must therefore be accessible and in good working condition at
all times. The device is operational when connected to the
mains voltage.

Important safety information
OperatingmanualHVB21,HVB 31 a.HVB32 - Version01-2021Apage 10
Adhere to all applicable national safety regulations and stand-
ards.
Excessmechanicalloads(e.g.falling,impacts,vibrations)may
damage the insulation used to provide protection from the
mains voltage.
High excess currents (lightning strikes, surges in the power
utility grid) may damage the insulation used to provide protec-
tion from the mains voltage.
Ifthereisnoinformationabouttheintendeduse(e.g.operating
site, ambient conditions), or the operating manual does not
include the corresponding information, you must consult the
manufacturer of this device to ensure that the device may be
installed. If you do not receive the required information from
the manufacturer, do not operate the device.
In rooms in which the climatic conditions vary (e.g. due to
sunlight), the device may only be operated if the permissible
ambient temperature can be maintained.
Disconnect devices with a damaged power cable from the
mains (unplug the power supply plug).
Always use the supplied power adapter (power supply unit)
and connect it to a power point with a voltage within the range
specified in the “Technical data” section. Failure to observe
this warning may result in personal injury or equipment/prop-
erty damage.
Do not install the device in locations with excessive dust formation,
as this may reduce its insulation from the mains voltage.
Electromagnetic compatibility (EMC)
In order to avoid malfunctions when operating radio and telecom-
munications equipment, as well as other operating units or broad-
casting services, the following must be observed:
Before installation, make certain that you have checked the
device for mechanical damage. Do not use damaged or bent
covers or housings.
During operation, the device must always be covered by the
components provided for this purpose. It is not permitted to
operate the device when the cover is open.
