Note during mains operation
Risk of lightning strikes
Lightning may enter the mains cables and data transmission cables and jump to a person.
Death, serious injury and burns can be caused by lightning strikes.
Take the following precautions:
• Pull out the power plug in good time when a thunderstorm is approaching.
• Do not touch mains cables and data transmission cables during a thunderstorm.
• Keep a sufficient distance from electric cables, distributors, systems, etc.
Risk of fire and electric shock
The On/Off button does not completely isolate the device from the power supply. If the
device is switched off with the On/Off button, there is still a risk of electric shock and fire, for
example, if the device or the connecting cables are damaged or in the event of improper
use.
When working on the device or if the device is not used for a long period of time, always
disconnect it fully from the power supply. Shut down the operating system and if you are
using the device in mains operation, pull out the power plug.
Note before connecting to mains operation
