18. Pull the whole module onto the installation stand. Keep the pipes and wires away from
the sharp edges and be careful not to damage the coolant connections.
19. Lift the module onto a pallet or other platform for transportation.
20. Install a new module in reverse order. Tightening torque for cooling connectors is
10 N·m (7.4 lbf·ft) in room temperature (around +20 °C [68 °F]).
Capacitors
The converter intermediate circuit employs film capacitors. Their lifespan depends on the
operating time of the converter, loading and ambient temperature. Capacitor life can be
prolonged by lowering the ambient temperature.
Capacitor failure is usually followed by the converter module and module 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.
