6AG1331-7KB02-2AB0 6AG1331-7KF02-2AB0 Plastic Cover

The S7-300 6AG1 331-7KB02-2AB0 6AG1 331-7KF02-2AB0 Module HMI Case, for example, must not be used without taking additional measures:
 in locations exposed to a high degree of ionizing radiation
 in hostile environments caused, for instance, by
– dust accumulation
– corrosive vapors or gases
– strong electric or magnetic fields
 in installations requiring special monitoring, for example
– elevators
– electrical installations in particularly hazardous areas
An additional measure might be, for instance, installation of the S7-300 6AG1331-7KB02-2AB0 6AG1331-7KF02-2AB0 Plastic Case in a cabinet or in a housing.
