Commissioning   
7.1 Measures prior to commissioning 
  1FT7 synchronous motors 
40  Operating Instructions, 04/2010, 610.40075.40b 
Electrical connection  
Make sure that: 
●  The grounding and equipotential bonding connections have been established correctly. 
●  The brake is operating correctly. 
●  The indicated speed limit n
max
 is not exceeded during operation on a converter. 
Monitoring equipment 
Make sure that: 
●  Appropriately configured control and speed monitoring functions ensure that the motor 
cannot exceed the permissible speeds specified on the rating plate. 
●  Any supplementary motor monitoring devices and equipment have been correctly 
connected and are fully functional. 
Forced ventilation 
All safety and functional issues must be checked prior to commissioning. A checklist, which 
does not claim to be exhaustive, is provided below to help you in this regard. 
Make sure that: 
●  The data for the forced ventilation unit matches the connection data. The forced 
ventilation unit must not be connected if the connection data differs from the data for the 
forced ventilation unit in any way that would result in overload. 
●  The electrical installation (e.g. protective conductor fitting) of the forced ventilation unit 
(including accessories) has been performed correctly. 
●  The mounting and electrical installation of safety-related components such as motor 
circuit breakers, protective grilles, etc., have been performed correctly. 
 
CAUTION 
 
 
Always operate the motor with the separately driven fan switched on.  
If the separately driven fan fails or the motor is operated for a short time without forced 
ventilation, this can cause it to overheat. This can result in material damage or destroy 
the motor completely.
