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
