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.
Fig. 3 - 19 Checking the overcurrent and short-circuit current trip thresholds
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.
Main power voltages Type
3x380 VAC ± 5% ZM-16-PKZ2
3x400 VAC ± 5% ZM-16-PKZ2
3x415 VAC ± 5% ZM-16-PKZ2
