Dimensioning

Warning: The signaling devices are procured on site. Automatic cabinets are not explosion-proof and may only be used outside explosion-prone areas. Signal sensors in potentially explosive areas must be connected via an intrinsically safe circuit, e.g. zener barrier or Ex-break relay. Directly connecting pumps in potentially explosive areas is not possible!
