Cleaning
NOTICE
Damage caused by aggressive cleaning agents
Aggressive chemical agents can damage the electronics. This can result in malfunction.
Never use any type of chemical agent or liquid.
● Only remove severe dirt and contamination after prior consultation with service experts for
the particular product.
Use a dry, clean, lint-free ESD cleaning cloth. Wipe all external parts of the rack with it. Make
sure that the dirt is not distributed, but actually removed by constant changes of the wiping
surface of the cloth. For significant levels of pollution and dirt, use an ESD cloth soaked in ethyl
alcohol (however, not so much that it drips from the cloth).
