What this chapter contains
This chapter explains the routine maintenance actions for the inverter.
General about maintenance
The inverter is a high-quality product which is designed to require very little
maintenance and downtime. In the event of a problem or malfunction in the system,
the built-in monitoring diagnostics are designed to highlight the nature of the problem
or required maintenance action. With optional accessories, remote monitoring can be
implemented by using the embedded fieldbus interface and the SREA-50 Remote
monitoring adapter.
Only a limited number of parts can be replaced. Replacement fans can be delivered
quickly through your installation company or local ABB service. In the event of severe
damage, the whole inverter will usually need to be replaced. In case of severe
inverter damage or an unidentified fault, please contact your installation company or
local ABB service.
Self-diagnostics
The inverter self-diagnostic functions are active by default. They are designed to
warn the user of maintenance triggers, faults, etc. For example, they tell you when to
change the fans, fuses and surge protection varistors.
In the unlikely event that the self-diagnostic feature fails, the whole inverter will need
to be replaced.
