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-
i
fi
cations 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
permitted to work on the device under the supervision of an experienced person. This
also applies to personnel undergoing general training. Comply with the legal minimum
age.
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 speci
fi
ed 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
Information
Mounting, electrical connection, and start-up operation may only be carried out by an
electrical specialist in accordance with electrotechnical regulations (e.g. EN 50110 or
EN 60204)!
Danger due to electric current
It is generally forbidden to carry out work on electrical live parts. Protection class of the
device when open is IP00! It is possible to touch hazardous voltages directly.
The safe isolation from the supply must be checked using a
two-pole
voltage detector.
