If you have reason to believe that the device can no longer be operated safely, disconnect it immediately
and make sure it is not unintentionally operated.
It can be assumed that safe operation is no longer possible if:
• thedevice,theremotecontrolortheconnectioncablesshowvisibledamage
• thedevicenolongerfunctions
• thedevicehasbeenstoredunderunfavourableconditionsforalongerperiodoftime
• thedevicehasbeensubjectedtoheavytransportstrain
Always observe the following safety instructions before cleaning or servicing the device:
Live components may be exposed if covers are opened or parts are removed (unless these parts
are intended to be removed without tools).
Connection points may also be live.
If the device needs to be opened for calibration, servicing, repair or replacement of parts or
components, it must be disconnected from all voltage sources first.
Any necessary servicing or repair on the open device must be carried out by a specialist who is
familiar with the risks involved and the relevant regulations.
Capacitors inside the device may still carry voltage even though they have been disconnected
from all power sources.

currentareused(see„TechnicalData“).
