Pull the module carefully out onto a table or other platform. Keep the module secured
to a hoist or equivalent to prevent the module from falling. For information on using the
lifting device, see
Converter module lifting device for drive cabinets hardware manual
(3AXD50000210268 [English]).
Reinstalling the module
1.
Push the module carefully into its bay.
2.
Fasten the retaining screws at the top and the bottom of the module.
3.
Reinstall the DC busbars at the top of the module.
4.
Reconnect the coolant pipes to the module.
5.
Reconnect the control wiring to the module.
6.
Fill up the cooling system. For instructions, see section
7.
Close the swing-out frame (if present). Reinstall all shrouds removed earlier.
Capacitors
The DC circuit of the power modules of the drive contain several electrolytic capacitors.
Their lifespan depends on the operating time of the drive, loading and ambient temperature.
Capacitor life can be prolonged by lowering the ambient temperature.
Capacitor failure is usually followed by damage to the unit 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. Contact an ABB service
representative for spare parts and repair services.
■
Reforming the capacitors
The capacitors must be reformed if the drive has not been powered (either in storage or
unused) for a year or more. The manufacturing date is on the type designation label. For
information on reforming the capacitors, see
Converter module capacitor reforming
instructions
(3BFE64059629 [English]) in the ABB Library (
).
If the drive module has been stored for one to three years, turn on the mains power for 30
minutes without load, then continue as usual.
If the drive module has been stored for less than a year, continue as usual.
Control panel
For detailed information on the control panel, see
ACx-AP-x assistant control panels user’s
manual
(3AUA0000085685 [English]).
■
Cleaning the control panel
Use a soft damp cloth to clean the control panel. Avoid harsh cleaners which could scratch
the display window.
■
Replacing the control panel battery
For instructions on how to replace the control panel battery, see the separate
ACx-AP-x
