Storage  

When  storing  for  a  long  period  of  time,  avoid  harmful  impacts  by  following  these 
steps: protect the motor by dry, air and dustproof package (plastic bags with drying 
agent and moisture indicator). The product should be stored in a vibration-free and 
water-protected premise at a constant temperature ranging from -20

C up to + 40

C.        

In  compliance  to  Chapter  8,  when  storing  a  product  for  more  than  three  months 
(motor standstill), maintenance should be determined before commissioning. In case 
of transshipment (especially over longer distances: e.g. sea), the packaging has to 
be checked whether it is suitable for transport and on the route. Damages caused by 
improper transportation, storage or installation are not covered by the warranty. 

 

1.8
