Replace the starting capacitor. 4. Undo the black fastening screws of the plastic side cover of the fan and lift the cover off.
Page 284: Capacitors
It is not possible to predict a capacitor failure. Capacitor failure is usually followed by damage to the drive and an input cable fuse failure, or a fault trip. Contact ABB if capacitor failure is suspected. Replacements are available from ABB. Do not use other than ABB specified spare parts.

Page 292: Cable Types
ACS550-02/U2 User’s Manual Cable types The table below gives copper and aluminium cable types for different load currents. Cable sizing is based on max. 9 cables laid on a cable ladder side by side, ambient temperature 30 °C, PVC insulation, surface temperature 70 °C (EN 60204-1 and IEC 60364-5-52/2001).
Page 293 ACS550-02/U2 User’s Manual NEMA Cable sizing is based on NEC Table 310-16 for copper wires, 75 °C (167 °F) wire insulation at 40 °C (104 °F) ambient temperature. Not more than three current- carrying conductors in raceway or cable or earth (directly buried). For other conditions, dimension the cables according to local safety regulations, appropriate input voltage and the load current of the drive.
