Intended Use

3.1.2 notes on the ex area

• The values for use within the Ex area are dependent on the

ambient temperature, i.e. the temperature class (gas), surface

temperature (dust), and medium temperature.

• If explosive media are used, this can result in additional explosion

risks.

• Use in an explosive atmosphere may be restricted by the control

system. Observe the operating instructions for the control system.

• Check that cleaning agents are approved for use in explosive

atmospheres.
