Measures before start-up
Rotating parts
Electrical machines contain dangerous rotating parts. Fatal or severe injuries and
substantial material damage can occur if the required covers are removed or if the
machines are not handled, operated, or maintained properly.
Before commissioning, attach the covers that prevent inadvertently touching active and
rotating components.
NOTICE
Damage caused by insufficient cooling
Effective cooling is no longer possible if air guidance of the machine is not provided as
intended. This can damage the machine.
Before commissioning, attach the covers in order to guarantee the required air guidance.

Example:
Critical resistance for U
690 V x 0,5 MΩ / kV = 0,345 MΩ
NOTICE
Critical insulation resistance reached or fallen below
If the critical insulation resistance is reached or fallen below, this can result in damage to
the insulation or voltage flashovers.
• Contact your Siemens Service Center.
• If the measured value is close to the critical value, you must check the insulation
resistance at suitably frequent intervals.
