I cannot find power values of 230V anti-condensation heating ( Z-option Q02 ) for 1MB1 motors of shaft height 71. In the catalog this shaft height is omitted even though such motors are produced.

For 1MB1 motors of shaft height 71 the standard heating is designed as can be seen below:

1MB1x1/x2/x3 (zones 2,21,22)        2x 7 W
1MB154x (zone 1 - Ex eb) 2x 7 W
1MB155x (zone 1 - Ex db eb)   1x 12,5 W

(2x7W means that there are two heating stripes – one for each winding side)
