This section describes the routine cleaning and inspection recommended as
regular maintenance.
Clean the PROFIBUS-DP Master Units regularly as described below in order
to keep it in its optimal operating condition.
• Wipe the Unit with a dry, soft cloth for regular cleaning.
• When a spot cannot be removed with a dry cloth, dampen the cloth with a
neutral cleanser, wring out the cloth, and wipe the Unit.
• A smudge may retain on the Unit from gum, vinyl, or tape that was left on
for a long time. Remove the smudge when cleaning.
Never use volatile solvents such as paint thinner or benzene or chemical
wipes. These substances could damage the surface of the Unit.
Be sure to inspect the system periodically to keep it in its optimal operating
condition. In general, inspect the system once every 6 to 12 months, but
inspect more frequently if the system is used with high temperature or
humidity or under dirty / dusty conditions.
