Siemens AG Operating Instructions 2.02 1PL618
The motors are certified for a wide range of installation and operating conditions. In some
cases, these conditions (e.g. rigid or vibration-isolated foundation design, use of sound-
absorbing elements) can have a significant influence on noise emissions.
When evaluating the noise levels at the workplaces of the system operators, consider the
fact that the A-weighted sound pressure level (measured in accordance with DIN EN 21680
Tl.1) of 70 dB(A) is exceeded when the three-phase motors are operated at nominal load.

3.2.2
Mounting
Requirements
In order to ensure smooth, vibration-free motor operation, a stable foundation design is
required, the motor must be precisely aligned, and the components that are to be mounted
on the shaft end must be correctly balanced.
Removing the cover sheets
Cover sheets are attached by means of the screw positions on the motor feet.
The cover sheets (1) have to be removed before mounting the motor
ແ

(1) Cover sheet (detailed view)
CAUTION
The cover sheets ensure the cooling of the motor.
Please make sure that the cover sheets are always screwed back onto the motor after
mounting the motor via the motor feet.
Fixing by means of motor feet
If the motor needs to be aligned, position metal shims underneath the feet in order to prevent
machine deformation.
The number of shims should be kept as low as possible i.e. stack as few as possible.
