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