Electrical cabinets are often designed as a central control point for automation and process control equipment.
Electrical cabinets are often designed as a central control point for automation and process control equipment. Inside the cabinet are PLCs, VFDs, and associated communication and control wiring. Safety always should be the first concern before opening a cabinet. It's easy to forget that working inside a cabinet can expose workers to dangerous voltages and short-circuit currents. Industrial control panels are required to have durable and legible labels that indicate the rated voltage, number of phases, and the frequency of any supply in the cabinet. Many panel doors now have arc-flash warning labels.
