Start-up and during operation
Caution!
•
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.
