Replacing filter mats

To prevent dangerous dust deposits from accumulating in the power unit components,
additional filter mats are attached to the outside of the device.
The device must not be operated when the filter mats are dirty. Dirty filter mats can cause a
premature thermal shutdown of the drive.
Danger due to arcing
Replacing the filter mats while the converter is in operation can cause hazards for
maintenance personnel due to arcing. This can result in death, serious injuries or material
damage.
● Do not replace filter mats while the converter is operational.
NOTICE
Damage due to dust deposits
Dust can enter the interior of the cabinet during filter mat replacement due to the suction of the
running cabinet fans. Dust deposits can damage the device.
● Ensure that no dust enters the cabinet when replacing the filter mats.
1. Remove the screws for the louvered fan grid in the cabinet door.
2. Remove the filter mat.
