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

Are the Units installed securely?
Are the Ethernet cable connectors
fully inserted and locked?
Replace a faulty EtherNet/IP Unit as soon as possible. If the built-in EtherNet/
IP port is faulty, replace the CPU Unit as soon as possible. We recommend
having spare Units available to restore network operation as quickly as possi-
ble.
Observe the following precautions when replacing a faulty Unit.
• After replacement, verify that there are no errors with the new Unit.
• When a Unit is being returned for repair, attach a sheet of paper detailing
the problem and return the Unit to your OMRON dealer.
