Note:
4. Input/output (main circuit) of the AC drive include harmonic components,
which may interfere with the AC drive attachment communications equipment.
Therefore, install an anti-aliasing filter to minimize the interference;
1. DC reactor, braking unit and braking resistor are optional accessories”.
2. P1 and(+) are short circuited in factory, if need to connect with the DC
reactor, please remove the contact tag between P1 and (+).
3. Do not install capacitor or surge suppressor on the output side of the AC
drive. Otherwise, it may cause faults to the AC drive or damage to the capacitor
and surge suppressor;
