3 Mounting
3.1 Safety instructions
Never mount or commission a damaged electric motor.
Never install the electric motor in a damaged machine.
Before mounting the electric motor, make sure it is suitable for your machine.
Only mount the motor using the fastening features provided.
The motor should not be exposed to knocks, e. g., with a hammer, or shocks when
mounting.
Make sure that all covers and safety devices are mounted. All safety devices must comply
with the latest regulations (e. g. EN 60204).
Air cooling:
Protective guards have to be fitted to the air inlets and outlets, if there is a risk of foreign
bodies falling into the fan during operation.
3.2 Installation, mounting
Prior to and during mounting, check that
the motor is not damaged (e. g. the shaft sealing ring must not have sustained any damage at all from
sharp or pointed objects).
the motor is not mounted in the danger zone of other equipment.
the motor is used for the designated purpose (comp. Section 1.2, Section 2.4).
Observe type plate details, warning labels, and signs.
anti-corrosion agents have been fully removed from the shaft ends.
If a common solvent such as acetone or a cleaning solvent is used, it must not be allowed to wet the
shaft sealing ring.
the motor is designed for the ambient conditions and environmental influences on site (comp.
Section 2.4).
the mounting space in the machine is suitable for the cooling method employed for the electric
motor. The motor has to mounted in such a way as to guarantee sufficient waste heat removal via
the housing and motor flange surfaces; during air cooling the incoming air and the outgoing air must
be able to flow freely so that the outgoing air is not drawn in again; at water cooling the connection of
cooling supplies is possible (compare chapter. 2.6 and 9).
That there is enough space in the machine to connect the motor and for inspection and maintenance
works. In order to obtain the installation dimensions of the motor including the tolerance
specifications refer to the technical documents or your dimension drawing
the motor can be mounted and operated with the connection data and fastening features provided.
The mounting dimensions of the motor and the tolerance details are provided in the technical
documentation.
When flanging to the motor, make sure that the flange surface is in good, even contact. The supports
and bearing surfaces must be clean and undamaged. They must be precisely aligned with the
connecting shafts to prevent exposure of the bearings, shafts and housing to damaging loads
through misalignment. When tightening the flange mounting screws (min. strength class 8.8), make
sure that the flange connection is not distorted.
no liquid can penetrate the upper bearing when installing vertically with the shaft end facing upwards.
