When working in areas where gases, dust and oils may be hazardous to func-
tionality, the controller must be operated in a control cabinet with a heat exchan-
ger or with suitable supply air.
Maximum permissible dust contents in the air circulating in the cabinet:
– Suspended solids 0.2 mg/m
3
– Deposits 1.5 mg/m

/h
Note
The dust precipitate must be removed at appropriate time intervals.
Relevant standards: EN 61000-6-3 and -4
Table 2-9 Limit values for radio interference suppression in industrial environments
Limit class as per EN 61000-6-4
