Prohibited Spacing Dimensions
………
NOTICE!
Risk of Material Damage from Incorrect Spacing of
Bus Bars!
Improper installation and incorrect spacing of individual
fixation units can lead to resonant vibrations at certain
intervals within a bus bar due to their natural frequency.
The bus bars may be subjected to very heavy
mechanical stress, and in extreme cases the insulation
may become damaged.
– It is imperative to adhere to the spacing
dimensions between the individual sliding
bearings (Bg), fixed bearings (Bf), and the
fixation units as shown in the installation
drawing.
– If the spacing dimensions cannot be adhered to
for reasons related to the performance of the
installation
or building interferences, any change must be
coordinated with RITZ Instrument Transformers
GmbH beforehand, and noted in the drawings.
