Connecting the power supply
Note before you connect the device
WARNING
Injuries to persons or damage to property when operated on an incorrect power supply
system
If you connect the device to an unsuitable power supply, the device receives voltages and
currents too high or too low.
Injuries to persons, malfunctions or a damage to the device can result.
Note the following information regarding the power supply system:
•
The permitted nominal voltage of the device must correspond to the local mains voltage.
•
Do not operate the device in non-grounded or impedance-grounded networks (IT
networks).
•
Operate the device only in grounded power networks (TN networks in accordance with
IEC 60364-1).
