AC Power cable and power connectors must always remain easily
accessible.
If the end environment restricts access to the power cable, disconnection must be
guaranteed using a separate cut-off fixture.
Do not disconnect the power from the product while the product
is switched on!
Performing a forced shut down may lead to loss of data or other undesirable effects!
Switch off using the power button to perform an orderly shutdown without data loss.
