Maintenance and cleaning
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, bring the connected motors and the machine into a
safe condition.
Carrying cleaning work during operation can lead to serious or fa-
tal injuries.
Do not submerge or spray the motor
Only wipe the motor with a cleaner and a cloth.
Cleaning by immersion may result in surface and motor damage
and leakage problems as a result of impermissible solutions.
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. Therefore, clean and service the components at regular in-
tervals.
Cleaning materials
Carefully clean the components with a damp cloth or brush.
For cleaning we have provided you with an overview of cleaning
agents to which the motors may be exposed up to a maximum con-
centration of 3%. You will also receive information about non-ap-
proved cleaning agents.
