Maintenance and cleaning

WARNING

Ensure safe condition for cleaning work

Basically, electronic devices are not fail-safe. The condition is always safe when the unit is switched off and not energized. Place the connected mains choke and the machine in a safe state for cleaning work.

Carrying cleaning work during operation can lead to serious or fatal injuries.

Do not touch hot surfaces

The surface of the housing can reach a temperature of 200 °C. Allow the mains choke to cool to below 40°C after switching off.

Ignoring this can lead to burns being sustained.

Note

Do not immerse or spray the mains choke

Wipe the mains choke only with a cloth.

Cleaning by immersion will destroy the mains choke. Impermissible solutions will damage the mains choke and surfaces.

Contamination, dust or chips can have a negative effect on the function of the components. In the worst case, contamination can lead to failure. Beckhoff recommends regular cleaning and maintenance of the components in a system at regular and required intervals.

As a rule, no special maintenance and cleaning measures are foreseen for mains chokes from the AX2090-ND80-xxxx series. A mains choke must be replaced in the event of malfunctions or faults.
