1) For 1LA9 motors with increased output, derating is necessary. Please contact your local Siemens office for advice.
The type approved and self-cooled motor series 1LP4, 1LP5, 1LP6 and 1LP7 in frame sizes 63 M to 315 L with derating without external fan and fan cover can be supplied on request.
For technical specifications and selection and ordering data, see the relevant sections of "Standard motors up to frame size 315 L".

The ordering example is valid for an order quantity of 1 item. For larger order quantities, a type test with heat run (order code F83) only has to be ordered for one motor. For all other identical motors, order code F83 is not required. The order must be subdivided into two order items
