Inspection And Maintenance - Siemens SIMOTICS T-1FW6 Operating Instructions Manual

For safety reasons it is not permissible to repair the motors:
Risk of injury when changing safety-relevant motor properties
Changing safety-relevant motor properties may result in death, serious injury and/or material
damage.
Examples of changed safety-relevant motor properties:
Damaged insulation does not protect against arcing. There is a risk of electric shock!
Damaged sealing no longer guarantees protection against shock, ingress of foreign bodies and
water, which is specified as IP degree of protection on the rating plate.
Diminished heat dissipation can result in the motor being prematurely shut down and in
machine downtime.
• Do not open the motor.
Note
If incorrect changes or corrective maintenance are carried out by you or a third party on the
contractual objects, then for these and the consequential damages, no claims can be made
against Siemens regarding personal injury or material damage.
Technical Support is available for any questions you might have. Contact data is provided in the
introduction.
Sharp edges and falling objects
Sharp edges can cause cuts and falling objects can injure feet.
