Inspection Procedure
This section describes the routine cleaning and inspection recommended as
regular maintenance.
Clean the PROFINET IO Controller Unit regularly as described below in
order to keep it in an optimum operating condition.
• Regularly wipe the Unit with a dry, soft cloth.
• If a spot cannot be removed with a dry cloth, dampen the cloth with a
neutral cleaner, wring out the cloth and wipe the Unit.
Never use volatile solvents such as paint thinner, benzine or chemical wipes. These
substances could damage the surface of the Unit.
Be sure to inspect the system periodically to keep it in optimum operating
condition. In general, inspect the system once or twice a year, but more
frequently if the system is used in high temperature or high humidity
environments or dirty/dusty conditions.
Prepare the following equipment before inspecting the system.
Required Equipment
Alcohol, and a clean cloth.
Optional Test Equipment
