Clean components mounted in the open of gross contamination as necessary.
To prevent dirt from penetrating into the open enclosure, it is recommended that
you roughly clean the component and its direct environment prior o each
opening.
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.

tion!). Also do not use aggressive
cleaning agents such as alcohol, organic
solvents or chemical detergents. These types of cleaning agent can attack
