General The apparatus has to be operated according to the appropriate data in the data sheet and in this instruction manual.
The data stated in the data sheet are restricted by this operating instruction!
The special conditions must be observed!
The ATEX Directive applies only to the use of apparatus under atmospheric conditions.
If you use the device outside atmospheric conditions, consider that the permissible safety parameters should be
reduced.
