To limit the heating of conducting parts, the minimum terminal cross sections, indicated in the table
have to be followed.

-    At  ambient  temperatures  >  40  °C,  supply  lines  and  cable/line  bushings  with  a  temperature 

 

resistance of at least 90 °C must be used.

-   The interpretation of the minimum terminal cross sections refer to the voltage range of 400 V, 

 

50 Hz at 30 °C ambient temperature.

5.2  Information for contactor and motor contactor selection

All protection devices and switching or monitoring units must be fitted in accordance with the local
safety regulations and established specifications (e.g. VDE) as well as with the manufacturer’s infor

-

mation. 

Motor protection switches are required!

 Motor contactors, feed lines, fuses and motor 

protection switches must be rated on the basis of the maximum working current (see name plate).
For motor protection use a current-dependent and time-delayed overload protection device for moni

-

toring all three phases. Set the overload protection device so that it must be actuated within 2 hours,
if there is 1.2 times the max. working current.

WARNING

Always install all electrical peripheral devices in an external 

control cabinet outside the explosion-endangered area!
