ACHTUNG
The following safety information must be observed when performing main-
tenance and repair work. Failure to observe this safety information may result in personal
injury due to electrical and thermal dangers!
The operating display only shows whether the DC current, which supplies the device components,
has been disconnected from the mains voltage. If the operating display (for the power supply unit
or the device) does not light up, this does not mean that the device has been fully disconnected
from the mains voltage. There may still be voltages in the device that are dangerous to touch. You
may therefore not open the device.
Read carefully: EN 60728 - Part 1 Safety requirements: No service work during thunderstorms.
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 disconnected from the mains and authorised experts must be consulted. The device may need
to be sent to the manufacturer.
