Product safety
The device conforms to the state of the art at the time of delivery and is fundamentally considered to
be reliable. The device and its accessories must only be used in a
fl
awless condition and installed and
operated in compliance with the assembly instructions and/or operating instructions. Operating out-
side the device's technical speci
fi
cations (see name plate and attachment / technical data) can lead to
a defect in the device and additional damage!
Information
In the case of a malfunction or a failure of the equipment check all functions with alarms in order to
prevent injury to persons or property. Note possibility of back-up operation. If used in intensive animal
environments, any malfunctions in the air supply must be detected as soon as possible to prevent the
development of a life-threatening situation for the animals. The design and installation of the system
must comply with local regulations and directives. In Germany these include DIN VDE 0100, the
animal protection and the keeping of working animals ordinance and the pig-keeping ordinance etc.
Also note the instructions of AEL, DLG, VdS.

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!
