High horsepower operator controls designed for hazardous locations


ROSS Systems and Controls (SysCon) offers new specialised control panels for use with high horsepower equipment in hazardous locations. A NEMA 12 main power panel, housing high voltage Variable Frequency Drives and motor protection fusing, is installed in a non-classified area and wired to a NEMA 7/9 operator station.

In the pictured system built for a 500-gallon Multi-Shaft Mixer, the explosion-proof panel is designed for Class 1, Division 1, Groups C and D and features a user-friendly color display for viewing agitator speeds, loads and temperature, Start/Stop push button controls, speed control potentiometers, Emergency Stop button, intrinsically safe barriers for temperature probe and safety switches, and a matching terminal strip to mate with the main power panel.
