Maintenance and cleaning
WARNINGBasically, electronic devices are not fail-safe. The condition is always safe when the unit is switched off and not energized. For cleaning work, place the connected brake resistors and the machine in a safe state.
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 brake resistor to cool to below 40 °C after switching off.
Ignoring this can lead to burns being sustained.
Only wipe the brake resistor with a cloth.
Cleaning by immersion will destroy the brake resistor. Impermissible solutions will damage the brake resistors 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.
No special maintenance and cleaning measures are usually foreseen for brake resistors from the AX2090-BW65-xxxx series. A brake resistor must be replaced in the event of malfunctions or faults.
