• 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.
• To prevent risks, damaged power cables may only be replaced by the manufacturer,
a professional workshop appointed by the manufacturer, or a similarly qualified
person.
• Never plug in or unplug the mains plug when your hands are wet.
• Only use the supplied mains adaptor as a power supply.
• 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.
• When setting up the product, make sure that the cable is not pinched, kinked or
damaged by sharp edges.
• 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. This poses a
risk of fatal injury due to electric shock! Allow the device to reach room temperature
before connecting and using it. This may take several hours.
• Do not place any containers filled 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 fire 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.
b) Miscellaneous
• 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.
PoE (Power over Ethernet)
The switch provides PoE on ports 1, 2, 3 and 4. The end device (i.e. a PoE-compatible network
camera) is automatically supplied with power via the network cable. The advantage of this is
that only one cable to the end device is necessary for both power supply and data transfer.
Do not exceed the permitted connected load of 15.4 W. Refer to the technical data
of the device you wish to connect.
Always use a fully-wired network cable to connect a PoE device. We recommend
using a CAT5e cable or better.
Review the operating instructions of each connected device.
