The VEGATRENN 149A Ex must be operated outside the explosion hazardous area.
The VEGATRENN 149A Ex must only be operated in areas, which are suitable for protection IP 20.
Otherwise mounting must be carried out in a housing with respective protection.
If the intrinsically safe circuit is led into dust-explosive areas of zone 20 or 21, please make sure that
the instruments connected to these circuits meet the requirements of category 1D or 2D and are
certified respectively.
A distance of 50 mm to the intrinsically safe terminals must be ensured when mounting.
