• Use safety shoes with a metal toe cap to prevent foot injury.
• Lift the drive module only by the lifting lugs.
1. Stop the drive and do the steps in section Electrical safety precautions (page 16)
before you start the work.
2. Disconnect the power cables.
3. Disconnect the power supply, BGDR and fiber optic cables from the drive module.
4. Disconnect the power supply cable and the fiber optic cables from the external
control unit and coil them on the top of the drive module.
5. Remove the screws that attach the drive module to the cabinet.
6. Install the new module in reverse order.
Capacitors
The DC link of the drive contains several electrolytic capacitors. Operating time, load,
and surrounding air temperature have an effect on the life of the capacitors. Capacitor
life can be extended by decreasing the surrounding air temperature.
Capacitor failure is usually followed by damage to the unit and an input cable fuse
failure, or a fault trip. If you think that any capacitors in the drive have failed, contact
ABB.

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, refer to
Capacitor reforming instructions
(3BFE64059629 [English]) .
Control panel
See ACS-AP-I, -S, -W and ACH-AP-H, -W assistant control panels user’s manual
(3AUA0000085685 [English]) .

before you start the work.
2. Remove the M4×8 (T20) screws at the ends of the control unit.
3. To see the battery, remove the XD2D terminal block.
4. Carefully lift the edge of the control unit cover on the side with the I/O terminal
blocks.
