6.2.3 Erecting the machine
DANGER!
Risk of death due to insufficient protection
classes.
Insufficient protection classes can lead to
considerable material damage, serious personal
injury or even death.
Therefore:
– Do not erect machines of protection class
≤
IP23 in the open.
In order to ensure that the machine runs quietly and with low
vibrations make sure of the following when erecting the machine:
the foundation must be stable
the foundation's natural frequency with the machine must be
sufficiently different to the rotary frequency and the double
mains frequency
the motors must be aligned accurately
the drive machines must be well balanced

6.2.4 Installation
Installation varies depending on the construction type. In case you
have any doubts contact the service department ( page 2).
When installing, always pay attention to the following points:
All connection elements (walls, ceilings etc.) must be of
sufficient size.
The rotor is dynamically balanced with a half feather key. Take
this into account when balancing the drive element.
Avoid incorrect belt tension ( catalogue). Cover couplings and
belt pulleys with a guard to protect accidental contact.
Fit and remove drive elements (couplings, belt pulley, toothed
wheels etc.) with the suitable devices.
Tighten all screw connections with the appropriate tightening
torque ( chapter "Tightening torque values for screws").
Fit construction types with the shaft ends at the bottom with
a cover to prevent foreign bodies from falling into the motor's
fan.
Any condensation drain holes must be positioned at the lowest
point of the motor when installed and cleaned of any impurities.
Take generally required measures for preventing accidental
contacts between drive elements
