Maintenance and cleaning

WARNING
Ensure safe condition for cleaning work
Basically, electronic devices are not fail-safe. The condition is al-
ways safe when the unit is switched off and not energized. For
cleaning work, place the connected brake resistors and the ma-
chine in a safe state.
Carrying cleaning work during operation can lead to serious or fa-
tal 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.
Do not immerse or hose down the brake resistor
Only wipe the brake resistor with a cloth.
Cleaning by immersion will destroy the brake resistor. Impermissi-
ble solutions will damage the brake resistors and surfaces.
Contamination, dust or chips can have a negative effect on the func-
tion 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 fore-
seen for brake resistors from the AX2090-BW65-xxxx series. A
brake resistor must be replaced in the event of malfunctions or
faults.
