Preparing for Use 5 
 
  Actions  are  taken  in  the factory to  ensure  the  motor arrives  at  its 
destination  in  optimal  conditions.  If  you  detect  packaging  damage  when 
receiving  your  motor,  immediately  submit  a  claim to the carrier and  notify 
your local SIEMENS sales office. 
Once the motor has been unpackaged, inspect it to make certain no damage 
has occurred  in  conduit  box,  fan cover  or  any part  of  the  equipment.  Put 
special attention in optional additional devices such as tachometers, brakes, 
blowers or auxiliary conduit boxes. 
Inspect and tighten all the screws and fittings that might have come loose 
during shipping. Rotate the shaft by hand to be sure it rotates freely. If it is 
suspected that the motor  has not been  transported  with sufficient care,  in 
such  a  way  that  it  might  have  suffered  structural  damage; end-shields  or 
motor covers must be removed to check for some internal damage. 
   
 CAUTION:  When  inspecting  the  motor,  be  aware  of  burrs  and 
sharp edges in the structure, as they might cause injury. 
 
    CAUTION. 
  1. - Before any handling, make sure you have your personal safety 
equipment such as shoes, gloves, girdle and lenses because if these 
preventive measures are not taken, physical damage may occur. 
  2. - Make sure before any handling that the motor to be prepared 
for  its  use  is  of  the  appropriate  environment  and  complies  with  the 
specifications according to the installation area.  
  3.  -  Explosion  proof  motors  are  designed  to  comply  with  the  U.L. 
label service procedure manual, therefore the repair or maintenance work of 
this  type  of  motors  must  be  performed  only  by  technical  personnel 
authorized by SIEMENS or in U.L. certified service centers. Violation of any 
of  the  above  will  invalidate the  U.L.  certification  as  well as the  SIEMENS 
warranty. 
  4.- Check the storage time of the equipment as well as verify the 
conditions  of  the  bearing  grease  and,  if  necessary,  change  or  renew  it 
before starting the installation.
