3.6.2.2 Inserting the motor protection trip block
Check the type of motor protection trip block before you insert it. The type depends on the op-
erating voltage.
Check the overcurrent and short-circuit current trip threshold settings.

Insert the motor protection trip block (3).
Push the yellow locking tab (4) down.
Close the gray protective flap (5).
Turn the rotary switch (6) clockwise as far as the stop.
