in accordance with national and regional regulations.
WARNING Electrocution
- In the case of a permanent connection, the appli-
ance must be able to be separated from the power
supply by an isolator that disconnects all poles with
at least 3mm contact separation.
- Do not install the appliance with a fixed power cable.
Note
- Observe the type plate. The specified voltage must
match the mains voltage.
- Ensure the on-site supply cable has an adequate
cross-section.
Note
In a non-domestic environment and in case of particu-
larly high demands on the appliance, such as permanent
continuous operation, we recommend installing the ap-
pliance as a permanent connection with a junction box.
Only an authorised electrician is allowed to make the permanent
connection to a junction box.
WARNING Electrocution
- Provide appropriate strain relief when making the
connection to a junction box.
- Ensure that the appliance is connected to the earth
conductor.

socket. Ensure that, after trimming the power cable, the
appliance can still be removed from the wall without a
problem.
