Operating instructions
4-port USB 3.0 metal hub, switchable
Item no. 1318454
Intended use
This product is designed to be connected to a computer with a USB interface and
provides four additional USB ports. The output ports can be turned on/off individually.
The product features overload protection (1.5 A per port). The USB hub transmits
signals from the computer (upstream) and from connected devices (downstream).
It is compatible with USB 3.0 and backwards compatible with USB 2.0/1.1. Power is
provided by the USB interface on the computer, or by an external power adapter if the
total current consumption of all the connected USB devices exceeds 900 mA (USB 3.0).
The product is designed to be mounted on flat surfaces (e.g. walls, underneath desks
etc.).
It is intended for indoor use only. Do not use it outdoors. Contact with moisture, e.g. in
bathrooms, must be avoided under all circumstances.
For safety and approval purposes (CE), you must not rebuild and/or modify this product.
If you use the product for purposes other than those described above, the product may
be damaged. In addition, improper use can cause hazards such as short circuiting,
fire, electric shock etc. Read the instructions carefully and keep them. Make this
product available to third parties only together with its operating instructions.

Safety instructions
Read the operating instructions carefully and especially observe the safety
information. If you do not follow the safety instructions and information on
proper handling in this manual, we assume no liability for any resulting
personal injury or damage to property. Such cases will invalidate the
warranty/guarantee.
• The device is not a toy. Keep it out of the reach of children and pets.
• Do not leave packaging material lying around carelessly. This may
become dangerous playing material for children.
• Protect the product from extreme temperatures, direct sunlight, strong
jolts, high humidity, moisture, flammable gases, vapours and solvents.
• Do not place the product under any mechanical stress.
• If it is no longer possible to operate the product safely, take it out of
operation and protect it from any accidental use. Safe operation can no
longer be guaranteed if the product:
- is visibly damaged,
- is no longer working properly,
- has been stored for extended periods in poor ambient conditions or
- has been subjected to any serious transport-related stresses.
• Please handle the product carefully. Jolts, impacts or a fall even from a
low height can damage the product.
• Also observe the safety and operating instructions of any other devices
which are connected to the product.
• The mains outlet must be located near to the device and be easily
accessible.
• As power supply, only use the supplied mains adapter.
• Only connect the power adapter to a normal mains socket connected to
the public supply. Before plugging in the power adapter, check whether
the voltage stated on the power adapter complies with the voltage of your
electricity supplier.
• Never connect or disconnect power adapters if your hands are wet.
• Never unplug the power adapter from the mains socket by pulling on the
cable; always use the grips on the plug.
• When setting up the product, make sure that the cable is not pinched,
kinked or damaged by sharp edges.
• Always lay the cables so that nobody can trip over or become entangled
in them. This poses a risk of injury.
• For safety reasons, disconnect the power adapter from the mains socket
during storms.
• If the wall plug transformer is damaged, do not touch it; there is danger
to life from electric shock! First, switch off the mains voltage to the mains
socket to which the wall plug transformer is connected (switch off at the
corresponding circuit breaker or remove the safety fuse, then switch off
at the corresponding RCD protective switch, so that all poles of the mains
socket are disconnected). You can then unplug the wall plug transformer
from the mains socket. Dispose of the faulty wall plug transformer in an
environmentally friendly way; do not use it any more. Replace it with a wall
plug transformer of the same design.
• Never use the product immediately after it has been brought from a cold
room into a warm one. The condensation generated could destroy the
product. The power adapter may also generate a fatal electric shock!
Allow the product to reach room temperature before connecting it to the
power supply and putting it to use. This may take several hours.
• Never pour any liquids over electrical devices or put objects filled with
liquid next to the device. If liquid or an object enters the interior of the
device nevertheless, first power down the respective socket (e.g. switch
off circuit breaker) and then pull the mains plug from the mains socket.
Do not operate the product anymore afterwards, but take it to a specialist
workshop.
• Use the power adapter provided if the total current consumption of all the
connected USB devices exceeds 900 mA (USB 3.0).
• Consult an expert when in doubt about operation, safety or connection of
the device.
• Maintenance, modifications and repairs are to be performed exclusively
by an expert or at a qualified shop.
• If you have questions which remain unanswered by these operating
instructions, contact our technical support service or other technical
personnel.
Mounting and connection
a) Installation on surfaces
• Place the hub on a flat, level surface or mount the hub on a suitably firm surface
with four appropriate screws, and if necessary, dowels (not included). The hub
can be mounted in any appropriate orientation (horizontal/vertical/overhead).
Ensure that there is a mains socket near to where the hub is mounted so that you
can plug in the power adapter (if needed).
b) Electrical connection/supply
• When the hub is in "bus-powered mode", the maximum current of 900 mA
provided by the USB 3.0 connection port is divided between one to four output
ports. This means that only approx. 225 mA is available per port; if fewer
ports are used, the total available current per port increases correspondingly
(900 mA when 1 port is connected, 450 mA for two ports and 300 mA for 3 ports).
Use the external power adapter when connecting devices with a higher total
current consumption to the hub.
• To connect the power adapter, insert the low voltage plug on the adapter into the
hub's power input port and then insert the mains plug into a mains socket. The red
LED turns on. This indicates that the hub is supplied with power.
The high-power variant of USB 3.0 provides a maximum current of 900 mA
per port. If all four of the hub's ports are connected, a current of 3.6 A would
be required.
