• Only connect the power adaptor to a normal mains socket connected to the public

supply. Before plugging in the power adaptor, check whether the voltage stated on

the power adaptor complies with the voltage of your electricity supplier.

• Never connect or disconnect power adaptors if your hands are wet.

• Never unplug the power adaptor 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 adaptor from the mains socket during

storms.

• Make sure that the mains cable is not squeezed, bent, damaged by sharp edges

or put under mechanical stress. Avoid excessive thermal stress on the mains

cable from extreme heat or cold. Do not modify the mains cable. Otherwise the

mains cable may be damaged. A damaged mains cable can cause a deadly

electric shock.

• Do not touch the mains cable if it is damaged. First, power down the respective

mains socket (e.g. via the respective circuit breaker) and then carefully pull the

mains plug from the mains socket. Never use the product if the mains cable is

damaged.

• Never pull the mains plug from the socket by pulling at the cable. Always pull it

from the mains socket using the intended grips.

• Unplug the mains plug from the mains socket if you do not use the device for an

extended period of time.

• To prevent risks, damaged power cables may only be replaced by the manufacturer,

a professional workshop appointed by the manufacturer, or a similarly qualied

person.

• Do not place any containers lled with liquids, such as cups, buckets, vases or

plants, on top of or near the product. Liquids could enter the housing and hence

affect the electric safety. There is also a risk of re or fatal electric shock! In such

a case, disconnect the mains supply to the mains socket (e.g. switch off the

circuit breaker) and then pull the mains plug. Do not operate the product anymore

afterwards, but take it to a specialist workshop.

• For installations in industrial facilities, follow the accident prevention regulations

for electrical systems and equipment of the government safety organization or the

corresponding authority for your country.

• In schools, educational establishments, hobby and self-help workshops, the

operation of this product must be monitored by trained personnel.

• Consult an expert when in doubt about operation, safety or connection of the

device.

• Maintenance, modications and repairs are to be performed exclusively by an

expert or at a qualied shop.

• If you have questions which remain unanswered by these operating instructions,

contact our technical support service or other technical personnel.

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.

dangerous playing material for children.

• Protect the product from extreme temperatures, direct sunlight, strong jolts, high

humidity, moisture, ammable 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

Operation

1. If necessary, attach the provided rubber feet to the bottom of the USB hub. They are

intended to guarantee stable footing and prevent surface damage.

2. Connect the power cable’s IEC plug to the corresponding socket on the power adaptor

(applies only to item no. 1642425).

3. Connect the round low-voltage plug of the power adaptor to the respective socket on the

USB hub.

4. Connect the power adaptor (or the power plug, item no. 1642425) to a household power

outlet.

5. Use the USB cable provided to connect the USB hub to a free USB 3.0 port on your

computer. It is not required to switch off the computer.

If your computer does not feature any USB 3.0 interface (e.g. on the mainboard or

a USB 3.0 card), you may also connect the USB hub to a USB 2.0/1.1 port. Devices

(whether USB 2.0 or USB 1.1) connected to the USB hub, however, will then run at

conventional USB 2.0/1.1 speeds only!

6. Push the On/Off button to switch the hub on. When the USB-hub is switched on, the power

indicator lights up above the On/Off switch. When you switch the USB-hub off, the power

indicator light turns off.

7. Windows recognizes new hardware and installs the driver automatically.

8. Connect your USB devices to the USB hub. The LED next to the USB port lights up once a

USB device is connected.

One USB 3.0 port can usually supply a current of 900 mA. The included power

adaptor delivers an output current of 2.5 A (item no. 1642424) or 4 A (item no.

1642425).

For this reason, not each USB port on the USB hub can provide 900 mA, rather a

maximum of two USB ports (item no. 1642424) or four USB ports (item no. 1642425)

can provide this output current.

As not every USB 3.0 device requires a power supply of 900 mA, several devices

can be connected to the USB hub.

Make sure that the total current consumption does not exceed 2.5 A (item no.

1642424) or 4 A (item no. 1642425).

9. Turn off the USB hub when it is not in use.

Tips & notes

• The USB 3.0 hub is compatible with USB 2.0/1.1. This means that conventional USB 2.0/1.1

devices can be operated through the USB 3.0 hub without problems. That, however, will not

make USB 2.0/1.1 devices any faster!

• In order to take advantage of the high speed of USB 3.0, all devices must support USB 3.0:

The USB device itself (e.g. an external hard disk), the USB hub and the USB controller in

the computer.

• The theoretical maximum speed of USB 3.0 (or USB 2.0/1.1) cannot be reached during

real operation. Reasons for that can be protocol information, the simultaneous operation of

several USB devices or speed limitations of the connected USB device or USB controller/

mainboard.

• DOS and the Windows Safe Mode do not support USB operation. Depending on the computer

or BIOS/setup settings, the use of a USB keyboard or USB mouse is still possible. This,

however, might require the USB keyboard or mouse to be connected to the USB interfaces

of the computer directly rather than to the USB hub itself.

• USB devices can be connected and disconnected during use. It is not necessary to switch off

your computer when connecting or disconnecting devices.

• When disconnecting a USB device during an active data transfer (e.g. when transferring

data from an external disk to the computer), the operating system might collapse. It could

furthermore cause data loss or even damage to the le system on the external drive.

• For Windows

XP, Vista™, 7 and 8, the menu bar displays an icon with arrowhead when

certain USB devices (e.g. USB hard disk) are connected. Use this icon to “disconnect” the

USB device from the computer. It is then safe to unplug the USB device.

• To connect USB 3.0 devices, only use the USB 3.0 cable intended for this purpose. Please

note that the use of very long USB 3.0 cables could slow down the data transmission rate.

Care and cleaning

• Disconnect the product from the power supply before cleaning.

• Do not use any aggressive cleaning agents, rubbing alcohol or other chemical solutions as

they can cause damage to the housing and malfunctioning.

• Clean the product with a dry, ber-free cloth.

• Do not immerse the product in water.

Disposal

Electronic devices are recyclable waste and must not be disposed of in the

household waste. At the end of its service life, dispose of the product according to

the relevant statutory regulations.

You thus full your statutory obligations and contribute to the protection of the

environment.
