3 Operation
3.1 Instructions for Initial Commissioning
Compare the available mains voltages to the values specified on the rating plate. The
impeller wheel on the mounted external fan must rotate in the direction of the arrow.
Mount all the guards before starting commissioning
Important!
Force-ventilated motors must only be run with separately driven fans.
In operation, the power unit and the motor coils are live! Never touch these components
during operation! Connect measuring instruments only when the motor is deenergized
and disconnected from the mains! After switching-off, the condensors are charged for
several minutes and take at least five minutes to discharge.
Speed monitoring sub-systems in the motor must not only be complemented by a
stand-alone monitoring sub-system by the motor in the case of speed-critical systems.
This speed governor, which is independent of the feedback control, can be imple-
mented by inductive, optical or centrifugal force dependent encoders.
Be particularly careful when touching the drive shaft directly or indirectly. You must only
do this when the drive is stationary and disconnected from the mains! Safety equipment
may never be dismounted or disabled
3.2 Wiring Diagrams
You connect the motor according to the supplied wiring diagrams. There are separate wiring diagrams
for the main motor, the fan motor, the brake and the tachometer.
3.3 Notes
The motor must be mounted on the appropriate attachment points (pedestal or flange)
in the installation position for which it was designed. When mounting, ensure that the
motor is attached unwarped
Before mounting a pulley or coupling, lightly grease the shaft end.
For mounting or removal, use the tapped hole in the shaft end.
You must not jar the shaft by hitting it on the end, since this may damage the shaft bearings and the
position encoder.
If a belt drive is used, the radial forces that were used as the basis of configuration must not be ex-
ceeded.
The allowed radial forces F
R
, which are specified in Section 3.4, apply to horizontal motor installation
with no additional axial forces. If axial forces occur, consult the manufacturer.
