This section describes the routine cleaning and inspection recommended as
regular maintenance.
Clean the PROFIBUS-DP Gateway 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 neu-
tral cleaner, wring out the cloth and wipe the Unit.
These substances could damage the surface of the Unit.
Be sure to inspect the system periodically to keep it in optimum operating con-
dition. In general, inspect the system once or twice a year, but more fre-
quently if the system is used in high temperature or high humidity
environments or dirty/dusty conditions.
Prepare the following equipment before inspecting the system.
