ATTENTION
infor-mation be observed when performing maintenance
and repair work. Failure to observe this safety information
may result in physical injury due to electrical and thermal
dangers!
The power indicator only shows whether the DC current, which
supplies the device components, has been disconnected from
the mains voltage. If the power indicator (for the power supply
unit or the device) does not light up, it does not mean that the
device has been fully disconnected from the mains voltage.
There may still be voltage in the device that is dangerous to
touch. Therefore, do not open the device.
Read carefully: EN 60728 – Part 1 Safety requirements: No
service work during thunderstorms.
Disconnect the mains plug before cleaning the device!
A defective device may only be repaired by the manufacturer
to ensure that components with the original specification are
used (e.g. power cable, fuse). Improperly performed repairs
may result in considerable dangers for the user or installer. If
malfunctions occur, the device must therefore be discon-
nected from the mains and authorised experts must be
consulted. The device may need to be sent to the manufac-
turer.
