b) Electrical safety
• Before connecting the product to the mains, check that your local A/C mains
voltage matches the specifications on the nameplate.
• Never pour liquids over electrical devices or place objects filled with liquid next
to the device. If liquid or an object does get inside the device, power down the
respective socket (e.g. switch off the circuit breaker), and then remove the mains
plug from the mains socket. Discontinue use and take the product to a specialist
repair centre.
• Never use the product immediately after it has been brought from a cold room into
a warm one. The condensation generated may destroy the product. The mains
adapter may also generate a fatal electric shock! Allow the product to reach room
temperature before connecting it and putting it to use. This may take several
hours.
• The mains outlet must be located near to the device and be easily accessible.
• Never unplug the mains plug by pulling on the cable. Always use the grips on
the plug.
• Unplug the mains plug from the mains socket if you do not plan to use the
appliance for an extended period of time.
• For safety reasons, disconnect the mains plug from the mains socket during
thunderstorms.
• Only use the network cable provided (or an identical replacement cable) to power
the product.
• Make sure that the mains cable is not squeezed, bent, damaged by sharp edges
or subjected to mechanical stress. Avoid excessive thermal stress on the mains
cable from extreme heat or cold. Do not modify the mains cable, as this may
damage the components inside the cable. Damaged mains cables can cause a
fatal electric shock.
• Do not touch the mains cable if there are any signs of damage. Power down the
respective mains socket (e.g. via the respective circuit breaker), and then carefully
unplug the mains plug from the mains socket. Never use the product if the mains
cable is damaged.
• Damaged mains cables must be replaced by the manufacturer, an authorised
repair centre or a qualified electrician.
• Never insert or unplug the mains plug when your hands are wet.
• When setting up the product, make sure that the cables are 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.
