35. Ventilation
Vent holes and cooling fins are to be kept free and the required minimum distance
must be observed. It is to be avoided that the heated up cooling air is taken in again.
In case of installation in the open the motors are to be protected against direct
environmental influences.
36. Voltage and frequency
The motors are designed for a mains voltage of 380 - 420V, 50 Hz or 420 - 480V, 60
Hz. Motors with an output of up to 2.2 KW inclusive are star connected and from 3.0
KW delta connected. On request, the motors can be supplied for other voltages up to
690V.
37. Output
The nominal motor outputs given in the selection table are intended for constant
operation and a mains connection at nominal voltage and nominal frequency. The
ambient temperature may not exceed 40° C. Certain o perating conditions, such as
ambient temperatures above 40° C or installation ab ove 1,000m above sea level as
well as high switching rates, acceleration of large inertias etc. require separate
inquiries and calculations.
38. Speed
The speeds given in the selection table are achieved at the nominal voltage, nominal
frequency and nominal load.
39. Protection system
Motors are designed to the protection system IP 55 (IEC publication 34-5).
40. Construction type and shape
The motors can be produced in the different basic construction shapes B3 (IM1001),
B5 (IM3001) and up to size 112 also in B14 (IM3601). The construction shapes listed
conform to the IEC regulation 34-7.
41. Cooling
The motors are cooled by an external fan covered by a fan cover. Forced ventilation
for frequency-converter duty is possible on request.
