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.
