ROSS SYSTEMS AND CONTROLS: Control Panels
Specialized control panels are available 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-gal multi-shaft mixer, the explosion-proof panel is designed for Class 1, Division 1, and Groups C and D, and features a 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.
