6-1-1

Cleaning

Clean the EtherCAT Slave Units regularly as described below in order to keep the network in its optimal
operating condition.
• Wipe the Unit daily with a dry, soft cloth.
• When a spot can't be removed with a dry cloth, dampen the cloth with a neutral cleanser (2% solu-
tion), wring out the cloth, and wipe the Unit.
• A smudge may remain on the Unit from gum, vinyl, or tape that was left on for a long time. Remove
the smudge when cleaning.
Precautions for Correct Use
Never use volatile solvents such as paint thinner, benzene, or chemical wipes. These sub-
stances could damage the surface of the Unit.
