3 Transport, installation and
assembly

3.1 Transport, storage

Transport damage
The shipping company must be notified immediately
of any damage detected after delivery of the machine.
The machine must not be put into operation if any
damage is found.
Transportation
Caution
The supplied rotor-locking device must be
mounted during transportation in order to
prevent damage to the motor. Do not remove
this device until before the power take-off
element is fitted. If the motor has to be
transported after the power take-off element is
fitted, other appropriate measures must be
taken to fix the axial position of the rotor (see
illustration below).
Vertical-design motors must always be
transported in the vertical position if the rotor is
not locked. If transport in a horizontal position
should prove to be necessary in special cases,
the rotor must be locked again before the
machine is turned. Vertical motors with suitable
bearings can be supplied in the horizontal
position from the manufacturing plant.

Warning
The motors may only be transported and hoisted
in a position corresponding to their type of
construction (i.e. horizontal construction types in
horizontal position and vertical construction
types in vertical position. The motors may only be
hoisted using the hoisting lugs provided on the
stator housing. Use appropriate rope guidance or
spreading equipment (for weight see rating plate
or technical data).
Warning
Only the intended openings, eyebolts and lifting
pin on the base plates may be used for
transporting motor sets. Always pay attention to
the carrying capacity of the lifting device. Motor
sets must not be lifted by attachment to the
individual motors.
For lifting assembled machine sets (such as
built-on gearboxes, fan units), always use the
lifting eyebolt(s) or lifting pegs provided on
both the units! Machine sets should not be lifted
by suspending the individual machines! Check
the lifting capacity of the hoist!
Note: The motors should not be lifted using the centre
holes on the shaft DE and NDE, because the weight of
the motor shall harm the bearing and reduce its
performance and operational life.
Storage
Storing outdoors
If possible choose a dry storage location safe from
flooding and free from vibrations. Repair any damage
to the packaging before putting the equipment in
storage, in so far as this is necessary to ensure proper
storage conditions. Position machines, devices and
crates on pallets, wooden beams or foundations that
guarantee protection against ground dampness.
Prevent the equipment from sinking into the ground
and the circulation of air underneath the equipment
from being impeded.
