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.
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.
