Maintenance

What this chapter contains

The chapter contains preventive maintenance instructions.

Safety

WARNING! Read the instructions in chapter
before performing any maintenance on the equipment. Ignoring the safety
instructions can cause injury or death.

Maintenance intervals

If installed in an appropriate environment, the drive requires very little maintenance.
The table lists the routine maintenance intervals recommended by ABB.
Reforming of capacitors
Visual inspection
Cooling fan replacement
(frame sizes R1...R2)
Tightness of input power cable,
motor cable and control cable
terminals

Fan

The drive's cooling fan has a life span of minimum 25 000 operating hours. The
actual life span depends on the drive usage and ambient temperature.
Fan failure can be predicted by the increasing noise from the fan bearings. If the
drive is operated in a critical part of a process, fan replacement is recommended
once these symptoms start appearing. Replacement fans are available from ABB.
Do not use other than ABB specified spare parts.
