Clean components mounted in the open of gross contamination as necessary.
We recommend cleaning the worst of the dirt on the enclosure and the area
directly around it each time before opening in order to prevent contamination
from entering the open enclosure.
To clean the module, wipe the enclosure surfaces with a damp, lint-free cloth. If
compressed air is available on site, blow off the worst of the dirt beforehand.
Keep the enclosure closed while doing so.
NOTE
Do not use high-pressure water blasters for cleaning (danger of water penetra-
tion!). Also do not use aggressive cleaning agents such as alcohol, organic sol-
vents or chemical detergents. These types of cleaning agent can attack the
surface of the enclosure.
IQ sensors The cleaning of the IQ sensors depends greatly on the respective application.
Instructions for this are given in the respective component operating manual.
A valve module for the compressed air-operated cleaning of sensors is available
as an accessory.
