Maintenance and Replacement
This section describes the routine cleaning and inspection recommended as
regular maintenance, as well as the Unit replacement procedure required if an
EtherNet/IP Unit needs to be replaced.
7-3-1
Cleaning
Clean the EtherNet/IP Unit 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% solution), 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.
!Caution
Never use volatile solvents such as paint thinner, benzene, or chemical wipes.
These substances could damage the surface of the Unit.

Inspection
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 humid-
ity or under dirty/dusty conditions.
Inspection Equipment
Prepare the following equipment before inspecting the system.
Normally Required
Equipment
Have a standard and Phillips-head screwdriver, multimeter, alcohol, and a
clean cloth.
Occasionally Required
Equipment
Depending on the system conditions, a synchroscope, oscilloscope, ther-
mometer, or hygrometer (to measure humidity) might be needed.
Inspection Procedure
Check the items in the following table and correct any items that are below
standard.
