Please observe before connecting
WARNING
Injury 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 that are 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 permissible rated voltage of the device must match the local supply voltage.
•
Operate the device only in grounded power supply networks (TN networks in
accordance with VDE 0100, Part 100 or IEC 60364-1).
•
Operation in non-grounded or impedance-grounded networks is not permitted.
Note
Operation with uninterruptible power supply
An uninterruptible AC power supply (UPS) must be used when this device is operated with a
PFC (Power Factor Correction) circuit that supplies a sinusoidal output voltage in normal and
buffer mode.
UPS characteristics are described and classified in the standards EN 50091-3 or
IEC 62040-3. Devices with sinusoidal output voltage in the normal and buffered mode are
identified with the classification "VFI-SS-...." or "VI-SS-....".
Note
The power supply of the device contains a PFC (Power Factor Correction) circuit to conform
to the EMC directive.
