Deactivating EMC capacitors (size 0 only)
Installation
2. Remove the two screws [A] securing the circuit board.
3. Install the screws in the plastic insulations provided [B].
4. Fasten screws to the unit [C].
5. Close the unit.
6. Attach the sticker provided to the unit.
Deactivating the EMC capacitors stops earth-leakage currents from flowing over the
EMC capacitors.
•
Please ensure that the earth-leakage currents are essentially only determined by the
level of the DC link voltage, the PWM frequency, the applied motor cable and its
length and the motor used.
When the suppression capacitors are deactivated, the EMC filter is no longer active.
