Safety instructions

Read  the  operating  instructions 

carefully and observe safety 

instructions. If you do not follow the 

safety instructions and information 

on proper handling in these 

operating instructions, we will 

assume no liability for any resulting 

personal injury or material damage. 

Such cases will invalidate the 

warranty/guarantee.

a) General

• 

The device is not a toy. Keep it out of the reach 

of children and pets.

•  Do not leave packaging material lying around 

carelessly. It may become a dangerous toy 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.

•  Handle the product carefully. Jolts, impacts or 

a fall even from a low height may damage the 

product.

•  Always observe safety and operating 

instructions of any other devices which are 

connected to the product.

•  Consult a technician if you are not sure how 

to use or connect the product, or if you have 

concerns about safety.

• 

Maintenance,  modifications  and  repairs  must 

be done by a technician or an authorised repair 

centre.

•  If you have questions which remain unanswered 

by these operating instructions, contact our 

technical support service or other technical 

personnel.

b) Adapter

•  The mains outlet must be located near to the 

device and be easily accessible.

•  Only power the product using the mains adapter 

provided.

•  Only connect the power adapter to a standard 

mains socket connected to the public grid. 

•  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 mains adapter from the mains 

socket by pulling on the cable; always use the 

grips on the plug.

•  For safety reasons, disconnect the power 

adapter from the mains socket during storms.

•  Do not touch the mains adapter if there are 

any signs of damage, as this may cause a fatal 

electric shock! Switch off the mains voltage 

to the socket containing the power adapter 

(switch off at the corresponding circuit breaker 

or remove the safety fuse, and then switch off 

at the corresponding RCD protective switch). 

You can then unplug the mains adapter from 

the mains socket. Dispose of the faulty mains 

adapter in an environmentally friendly manner 

and discontinue use. Replace it with a power 

adapter of the same design.

c) Setup

•  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.

d) Operation

•  Never use the product immediately after it has 

been brought from a cold room into a warm 

one. The condensate generated can possibly 

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.

•  Never pour liquids over electrical devices 

or  place  objects  filled  with  liquid  next  to  the 

product. If liquid or an object does enter the 

interior of 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.
