Caution<br />
The motor overload protection switch must be set to the nominal current stated in the table in each case.<br />
The separate fan current may only be operated within the permissible voltage range (230 V, 50 Hz and<br />
265 V, 60 Hz). In the case of deviating voltages you must use a transformer.<br />
