Maintenance 103
Maintenance intervals
The maintenance intervals recommended by ABB are for a typical inverter, in a
typical location for a typical operating duration. Shorten the maintenance intervals, if
the inverter is in extreme environmental conditions.
Interval Action Instruction
Monthly Read the event
log.
Use the control unit to read the recent event logs from the
Events view.
The events are kept in the memory until the memory is full.
When the event memory is full, the inverter removes the
oldest events.
Make sure that
the fans
operate.
Read the Events view for possible fan faults.
The fans operate only when cooling is required.
Replace the fan(s) when the inverter displays a fan fault or
a replacement reminder.
Examine the
operating
environment.
Make sure that the inverter is in the intended operating
environment.
Make sure that the installation environment is clean, dry,
and free of obstacles, and that the ambient temperature is
not too high.
Clean the
operating
environment.
Clean the inverter installation space and mounting area
regularly to remove dust and dirt. This prevents clogging of
the fans and heat sink of the inverter.
Monthly
(Yearly if the
inverter is
indoors with
restricted
access)
Examine the
connections.
Make sure that the cables are correctly routed. Cables
must be tidy, secure and in good condition.
Make sure that the connectors are correctly connected and
that they are in good condition.
Make sure that the screw and spring terminal connections
are tight.
