Safety precautions for electrical components
The functions and operating safety of the device are guaranteed only under the
climatic conditions that are specified in TECHNICAL DATA. If the device is transported from a
cold to a warm environment, condensation may cause the device to malfunction or may even
destroy the device. Because of this, you must ensure that the device has acclimatised to the
ambient temperature before using it.
If you have any doubts that the device can be operated safely, do not operate it.
Your safety may be adversely affected by the device, if for example:
• it is obviously damaged
• it no longer works as specified
• it has been stored in unsuitable conditions for some time,
if in doubt, send the device to the manufacturer for repair or maintenance
Observe the safety precautions and the assembly and operating instructions of
connected devices.
