Maintenance and hardware diagnostics
What this chapter contains
The chapter contains preventive maintenance instructions and LED indicator
descriptions.
Safety
WARNING! Read the instructions in chapter Safety on the first pages of this manual
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.
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.
When the Assistant Control Panel is in use, the Notice Handler Assistant informs
when the definable value of the operating hour counter is reached (see parameter
2901 ). This information can also be passed to the relay output (see parameter 1401 )
regardless of the used panel type.
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.
