Checking and replacement indications
Filter mats should be checked regularly. The
intervals in which the mats are checked depend
on the cleanliness of the cooling air.
The filter mats are monitored by a pressure sensor.
When the mats are clogging and the pressure drop
reaches the specified final pressure loss, the
message Conv1CoolAirFilter comes up on the CDP
control panel and the alarm/fault pilot light on the
control compartment door illuminates.
Replacement
Although checking and removing of a filter mat can
be performed during operation of the drive, it is
easier to do when the drive is shut down.
When replacing a filter mat while the drive is
running, work carefully to prevent foreign matter
from entering the drive. Also, pay attention that
dust accumulated on the filter mat is not sucked
into the cabinet.
Note: ABB recommends removing the old filter mat
by rolling it down from the top to the bottom.
Filter mat replacement procedure
Filters can be replaced while the drive is running,
as they are accessible from the outside. Caution
