condition and installed and operated in compliance with the operating instructions.
Operating outside the device's technical specification (see technical data) can lead to a
defect in the device and additional damage!
2.4 Requirements placed on the personnel / due diligence
Persons entrusted with the planning, installation, commissioning and maintenance and
servicing in connection with the frequency inverter must have the corresponding qual-
ifications and skills for these jobs.
In addition, they must be knowledgeable about the safety regulations, EU/EC directives,
rules for the prevention of accidents and the corresponding national as well as regional
and in-house regulations. Personnel to be trained or instructed and apprentices are only

2.5 Start-up and during operation
Attention!
•
During commissioning, unexpected and hazardous conditions can arise in the
entire installation due to defective adjustments, defective components or incorrect
electrical connections. Remove all persons and objects from the hazardous area.
•
During operation, the device must be closed or installed in a control cabinet. Fuses
may only be replaced by new ones and must not be repaired or bypassed. The
data for the maximum line fuse are to be considered absolutely (see Technical
data). Use only fuses specified in schematic diagrams.
•
Any faults detected in the electric system/modules/operating equipment must be
corrected immediately. If these faults are not corrected, the device/system is
potentially very dangerous. The device/system must therefore not be operated
when it is faulty.
•
Pay attention to smooth, low vibration running of the motor/fan, the appropriate
instructions in the drive documentation must be observed!
2.6 Work on the device
