9.5.1

Removing dust deposits

Remove dust deposits at least once per year. You can use an ESD brush or an ESD vacuum
cleaner. The ventilation openings in the cabinet must never be obstructed.
NOTICE
Cleaning fiber-optic cables and electronic components with a damp rag
Fiber-optic cables, fiber-optic cable bundles and electronic components can be damaged if
cleaned using a damp rag.
If the components are very dusty, remove the dust using a dry, lint-free cloth. In so doing, do
not bend the fiber-optic cables.
NOTICE
Material damage caused by aggressive cleaning agents
Aggressive chemical agents can damage the electronics. This can cause the converter to
malfunction.
Never use any type of chemical agent or liquid. Only clean a very dirty converter after first
discussing the situation 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).
9.5.2

Cleaning aluminum parts

The surface of untreated aluminum is always covered by a thin but dense oxide skin. The
affinity of aluminum to oxygen is sufficiently strong that if the oxide skin is scratched, the metal
reacts immediately with oxygen in the air. This forms a new oxide skin. This natural oxide layer
acts as surface protection and is the reason for the good weathering resistance of aluminum
materials. In most cases, this means that additional protective measures are superfluous.
