Fastening to

ange
(assembly of axial fans / fans of design A, D ..) and
(assembly of radial fans of design RH).
•
If the motor is used to drive fan impellers or other components, please note the
maximum permissible speeds of the impeller or the component to be driven.
•
The max. permissible mass of the impeller ort he component to be driven must be
inquired from and con
fi
rmed in writing by ZIEHL-ABEGG.
•
Motors are not balanced as standard, a complete balancing with mounted fan impeller
is necessary. The balancing must be done on the fan impeller. The pertinent regu-
lations must be observed.
Design K (with rotor
fl
ange) or D (with o
ff
set rotor
fl
ange) as a drive for fans:
•
During assembly of the fan impellers or other components, no inadmissible force may
be applied to the motor bearing.
•
Centre the fan impeller accurately and mount without tension on the rotor
fl
ange, the
fan wheel must lie
fl
at.
•
Use suitable screws for fastening the fan impeller on the rotor
fl
ange and
fi
t as
suitable screw lock.
•
Every screwing case must be tested for suitability.
•
The permissible area pressing of the rotor
fl
ange may never be exceeded (depending
on the contact surface).
•
Too great a screw overhang is not permitted and can lead to scraping or blocking of
the rotor on the
fi
xed motor
fl
ange.
•
Motors are not balanced as standard, a complete balancing with mounted fan impeller
is necessary. The balancing must be done on the fan impeller. The pertinent regu-
lations must be observed.
