Maintenance and cleaning

WARNING

Ensure safe state for cleaning work

Basically, electronic devices are not fail-safe. The condition is always safe when the unit is switched off and not energized. For cleaning work, bring the connected braking resistors and the machine into a safe state.

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

WARNING

Do not touch hot surfaces

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

Ignoring this may result in severe burns.

Notice

Damage due to improper cleaning

The braking resistor and its surface can be damaged by incorrect cleaning.

Only wipe the braking resistor with a cloth
Do not immerse or hose down the braking resistor
Only use approved cleaning solutions

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.

No special maintenance and cleaning measures are usually foreseen for braking resistors from the AX2090-BW80-xxxx series. A braking resistor must be replaced in the event of malfunctions or faults.
